15 Chapter 1 Introduction 1.1 Overview This manual describes the technical characteristics, applications, installation and operation of the HS-ETH family of Ethernet I/O modules for the Megaplex-2100 and Megaplex-2104 modular E1/T1 multiplexer systems. The HS-ETH modules are available in the following versions: HS-ETH/B: basic HS-ETH modules with high-performance, self-learning 10BaseT Ethernet remote bridges. HS-ETH/V: HS-ETH modules with high-performance, self-learning 10BaseT Ethernet remote bridges with VLAN support. HS-ETH/F: HS-ETH modules with high-performance, self-learning 10/100BaseT Ethernet remote bridges with VLAN support. Note HS-ETH/R: HS-ETH modules with high-performance IP routers with 10BaseT Ethernet interfaces. In this manual, the generic term HS-ETH is used when the information is applicable to all the HS-ETH versions, and the term Megaplex is used when the information is applicable to both the Megaplex-2100 and Megaplex-2104 chassis types. The complete designation is used only for information applicable to a specific equipment version. Each HS-ETH version can be ordered with one, two or four independent channels. Each channel has an Ethernet interface for the local LAN, and uses the link between Megaplex-2100 or Megaplex-2104 units as its WAN connection. Each Ethernet interface is terminated in an eight-pin RJ-45 connector. 1.2 Applications HS-ETH/B, HS-ETH/V and HS-ETH/F Modules In a typical application, channels of two HS-ETH/V modules installed in two different Megaplex units are used to provide a bridging connection between two LANs. A typical system configuration is shown in Figure 1-1. HS-ETH MP-2100/2104 Ver. 10 Applications 1-1

16 Chapter 1 Introduction Installation and Operation Manual Notes The main difference between the HS-ETH/B and HS-ETH/V versions is that the /V version adds VLAN support. Therefore, the following application refers only to the HS-ETH/V version. The HS-ETH/F version is similar to HS-ETH/V, and in addition it also supports operation at 100 Mbps and autonegotiation. Each channel of a HS-ETH/V module operates independently of the other channels, therefore a multiple-channel HS-ETH/V module can simultaneously provide several bridging connections, either by using different timeslots on the same Megaplex main link, or timeslots on different main links of the same Megaplex chassis. For example, when the Megaplex chassis is equipped with two ML-2E1 or ML-2T1 modules, each of the four HS-ETH/V channels can use a different Megaplex link as its WAN connection. The main link bandwidth assigned to each HS-ETH/V channel can be selected in 64 or 56 kbps steps, in accordance with the volume of traffic expected between the nodes attached to two LANs, and the requirements of the applications run on these nodes. HS-ETH/V is fully compatible with other bridges/routers which support the HDLC protocol on the WAN. This enables, for example, a stand-alone WebRanger II remote access server (also offered by RAD) installed at the central office to communicate with the equipment attached to branch office LANs via a HS-ETH/V module at each branch office.

Typical HS-ETH/V Application HS-ETH/F has the added advantage of compatibility with both 10BaseT and 100BaseT LANs. The user can select a specific rate as part of the channel configuration, or enable autonegotiation. 1-2 Applications HS-ETH MP-2100/2104 Ver. 10

17 Installation and Operation Manual Chapter 1 Introduction HS-ETH/R Module HS-ETH/R modules can be used in two primary applications: Provide IP connectivity between LANs connected to the HS-ETH/R channels, using the Megaplex main links to provide the WAN connections. In this application, HS-ETH/R modules are installed in different Megaplex units, in a configuration similar to that shown in Figure 1-1. Each channel of a HS-ETH/R module operates independently of the other channels, thereby enabling a multiple-channel HS-ETH/R module to simultaneously provide several WAN links, either by using different timeslots on the same Megaplex main link, or timeslots on different main links of the same Megaplex chassis. The main link bandwidth is independently selectable, in 64 or 56 kbps steps. Provide access to IP nets for LANs connected to the HS-ETH/R channels. In the application shown in Figure 1-2, HS-ETH/R modules installed in remote Megaplex units connect to the Internet, to a private IP net, or to the enterprise intranet, using the Megaplex links as WAN links.

18 Chapter 1 Introduction Installation and Operation Manual The protocols used on the WAN link by each HS-ETH channel can be configured in accordance with the required application: Point-to-Point Protocol (PPP), HDLC or Frame Relay. 1.3 Physical Description All the HS-ETH module versions occupy one module slot in the Megaplex chassis. Switches are used to configure the operating mode of each channel interface. All the other module characteristics are controlled by software. HS-ETH/B Panel Figure 1-3 shows the panel of a typical 4-channel HS-ETH/B module. Each channel is assigned its own panel area, identified as NET1 through NET4 (in accordance with the number of channels supported by the module). Each channel has its own set of components, which includes an RJ-45 connector for the physical interface and four indicators. Channel indicator functions are explained in Table 1-1.

Each HS-ETH/F channel operates as a bridge. For the HS-ETH/B and HS-ETH/V, the operating mode of each channel can be independently configured by means of an internal switch to operate as a bridge or as a LAN extender: In the bridge mode, the channel filters the packets received from the local LAN and transfers through the link only frames destined to another LAN In the LAN extender mode, the channel does not filter the frames received from the LAN, but transfers all the frames through the link. HS-ETH/V and HS-ETH/F channels also support VLANs (maximum frame size of 1536 bytes), and can transfer both tagged and untagged frames. Filtering Functions Bridge Mode HS-ETH/B, HS-ETH/V and HS-ETH/F channels operate in a way similar to a media access (MAC) layer remote bridge with self-learning capabilities: During its operation, the channel automatically recognizes the addresses of the nodes attached to the LAN connected to its Ethernet interface. Using the collected information, the channel filters the local LAN traffic and forwards through the main link only multicasts, broadcasts, and packets addressed to nodes not attached to the local LAN. 1-8 Functional Description HS-ETH MP-2100/2104 Ver. 10

23 Installation and Operation Manual Chapter 1 Introduction Since the Ethernet bridges operate at the physical and data link layers of the OSI model, they are completely transparent to higher level protocols, such as TCP/IP, DECnet, XNS, ISO, and to operating systems, such as NetWare, VINES, and 3COM+. The HS-ETH/B and HS-ETH/V module channels can support up to 256 nodes at each end of the link. The LAN table can include up to 10,000 and 2,000 addresses, respectively. The bridge filtering and forwarding rate is up to 2,000 frames/sec. The actual forwarding rate toward the WAN depends on the main link bandwidth assigned to each channel. The bridge has negligible delay (latency of a single frame), and its buffer has a capacity of 256 frames. The HS-ETH/F module channels can support up to 256 nodes at each end of the link. The LAN table can include up to 2,000 addresses. The maximum bridge filtering and forwarding rate is 150,000 frames/sec, which is the maximum frame rate at 100 Mbps. The actual forwarding rate toward the WAN depends on the main link bandwidth assigned to each channel. The bridge has negligible delay (latency of a single frame), and its buffer has a capacity of 120 frames. The user can enable or disable the forwarding of multicast messages from the LAN to the WAN. HS-ETH/R Module Channel Functions The HS-ETH/R module includes one, two or four independent high-performance IP routers (in accordance with the number of channels one for channel). Each IP router is based on the ChipRouter subsystem offered by RAD, and has two interfaces: Ethernet interface, for connection to the local LAN WAN interface, which connects to an external main module port through one of the Megaplex TDM buses. The main link port provides the WAN link to the remote HS-ETH/R module. The bandwidth allocated to the HS-ETH/R channel is user-selectable (see additional information in the Main Link Bandwidth section below). Routing Functions In the transmit direction, the IP router of each HS-ETH/R channel analyzes each Ethernet frame received by its local LAN interface and determines whether the IP packet is destined to an IP address that can be reached through this LAN. If not, the HS-ETH/R channel forwards the packet to the WAN (through the main link port). In the receive direction, the IP router forwards to the local LAN all the IP packets received from the WAN having an IP address that can be reached through this LAN. Other packets are discarded. HS-ETH/R IP routers include hardware filters, which handle all the filtering operations at wire speed in both the LAN-to-WAN and WAN-to-LAN directions, HS-ETH MP-2100/2104 Ver. 10 Functional Description 1-9

24 Chapter 1 Introduction Installation and Operation Manual without dropping packets. Filtering and forwarding are performed at the maximum rate of 35,000 and 30,000 frames per second (wire speed), respectively. The internal buffer can hold 256 frames having a maximum size of 1534 bytes and the throughput latency is one frame. The protocols used on the WAN link by each HS-ETH/R channel can be configured in accordance with the required application: Point-to-Point Protocol (PPP). This protocol can be used for connection to another PPP-compliant access server, or to a backbone router or gateway. The HS-ETH/R support automatic negotiation on power-up and support for PAP and CHAP authentication. HDLC. This protocol is especially important for broadcast and multicast applications, where bandwidth overhead is critical. Frame Relay. When this protocol is used, an HS-ETH/R channel can be used as a Frame Relay Access Device (FRAD) with integral IP router. When the Frame Relay protocol is selected, the HS-ETH/R channel supports RFC 1490 on the WAN link for a single DLCI, with automatic detection of the DLCI and support for the maintenance protocol. This protocol enables the HS-ETH/R channel to be used as the termination unit for IP services over Frame Relay on the customer s premises, connected to a Frame Relay switch in the backbone through a Megaplex main link. HS-ETH/R IP routers also support IP multicast at wire speed, making it suitable for any multicast environment including high-speed downstream environments, such as satellite and xdsl. Users on the LAN register with the HS-ETH/R IP router for an IP multicast group using the IGMP protocol. Support for DHCP Relaying The HS-ETH/R IP router can also be configured to serve as a DHCP relay for the local LAN nodes. This function is enabled simply by specifying the IP address of the desired DHCP server. LAN Interface Characteristics HS-ETH/B, HS-ETH/V and HS-ETH/R Modules The LAN interfaces of the HS-ETH/B, HS-ETH/V and HS-ETH/R modules comply with IEEE and Ethernet V2. The physical LAN interface is 10BaseT and each channel interface is terminated in an RJ-45 connector. The interface connector is wired as an Ethernet station connector: Use a straight cable to connect the channel interface to a 10BaseT Ethernet hub port Use a crossed cable for connection to another station connector, for example, for direct connection to a PC Ethernet port. Each interface can be independently configured to operate in the half-duplex or full-duplex mode, by means of switches located on the LAN interface board of the module Functional Description HS-ETH MP-2100/2104 Ver. 10

25 Installation and Operation Manual Chapter 1 Introduction Note For all the HS-ETH versions, the WAN side always operates in the full-duplex mode. HS-ETH/F Modules The HS-ETH/F modules have 10/100BaseT LAN interfaces. Each channel interface is terminated in an RJ-45 connector, wired as an Ethernet station connector (same as for HS-ETH/B, HS-ETH/V and HS-ETH/R modules). The operating mode of each interface can be determined in two ways: By specifically configuring the mode (half-duplex or full-duplex) and the rate (10 or 100 Mbps) at which the port operates By enabling autonegotiation. The autonegotiation process uses a standard protocol that permits intelligent 10/100BaseT Ethernet ports to automatically select the mode providing the highest possible traffic handling capability supported by the two ports at the end of a link. Therefore, when enabled, the channel interface automatically selects the appropriate operating mode as soon as it is connected to a LAN or to another Ethernet port. With autonegotiation, additional capabilities are also available: Automatic detection and correction of MDI/MDIX crossover and polarity Use of flow control in the full-duplex mode (backpressure flow control in the half-duplex is also selectable). The operating mode of each interface and the use of the additional capabilities are selected by means of switches located on each LAN interface board. Timing The interface timing is always locked to the Megaplex nodal clock. An HS-ETH channel cannot be selected as a nodal clock reference source. Main Link Bandwidth The full-configuration (4-channel) HS-ETH module has two TDM bus interfaces, which can connect to TDM buses 1 and 2 of the Megaplex chassis. Each TDM bus interface serves two channels: one interface handles channels 1 and 3, and the other handles channels 2 and 4. As a result, the total number of timeslots that can be assigned to one pair of channels cannot exceed 31. The main link bandwidth to be used to transfer the WAN traffic of each channel can be selected in accordance with the desired throughput. The available selections are multiples of 64 kbps (n 64 kbps) and multiples of 56 kbps (n 56 kbps), where n (the number of main link timeslots to be assigned to the channel) can be selected from 1 up to the maximum number of timeslots available on the corresponding main link port. The data rate of each channel can be independently selected. Note however that because pairs of channels (1 and 3, 2 and 4) share a common TDM bus interface, the total number of timeslots that can be assigned to one pair of channels cannot exceed 31. For example, if channel 1 is configured for a rate of kbps, the maximum allowed rate for channel 3 is kbps. HS-ETH MP-2100/2104 Ver. 10 Functional Description 1-11

26 Chapter 1 Introduction Installation and Operation Manual Another restriction applies if you want to operate channels at rates from different groups of rates (that is, some channels at rates which are multiples of 64 kbps and other channels at rates which are multiples of 56 kbps): always select rates from the same group for a given pair of channels (1 and 3 or 2 and 4), and from the other group for the other pair of channels. For example: You can select a rate which is a multiple of 64 kbps for channel 1, and a rate which is a multiple of 56 kbps for channel 2 You cannot select a rate which is a multiple of 56 kbps for channel 1, and a rate which is a multiple of 64 kbps for channel 3. The Megaplex system supports flexible timeslot routing: the user can select the main link module and port that will carry the HS-ETH channel traffic, and the timeslot(s) assigned to each HS-ETH channel in main link port frame. Management HS-ETH operation is fully automatic, and includes automatic link start-up and recovery. For both the HS-ETH/V and HS-ETH/R modules, all the link and system parameters are programmed by means of the Megaplex system management. The HS-ETH/R module requires additional configuration activities for its IP routers: these activities are performed using Telnet, through its local Ethernet interface. Indications The HS-ETH modules provide status indications by means of the dedicated indicators located on the module panel. The indications available for each HS-ETH/B and HS-ETH/V channel include the reception and transmission of packets on the local LAN, and collision and link state indicators. HS-ETH/R channels provide similar indications, except that the collision indication is replaced by buffer overflow/underflow indications HS-ETH/F channel indications include link state, LAN activity, and LAN operating rate. Diagnostics The HS-ETH module performs automatic self-test upon power-up. In addition, the module supports local and remote loopback, controlled by means of the Megaplex system management, and can also be tested by means of the test subsystem of the main link modules installed in the chassis. Caution Remember that any test or loopback disrupts the traffic on the LAN connected to the module channel being tested Functional Description HS-ETH MP-2100/2104 Ver. 10

36 Chapter 2 Installation and Operation Installation and Operation Manual 2.4 Connecting the Cables Each HS-ETH channel has an RJ-45 connector wired in accordance with Table 2-6. Table 2-6. HS-ETH Channel Connector, Pin Functions Pin Function 1 Transmit output + 2 Transmit output 3 Receive input + 4 Not connected 5 Not connected 6 Receive input 7 Not connected 8 Not connected To connect the cables to the HS-ETH module ports: Identify the cable intended for connection to each LAN connector of the module, and connect the cable to the module connector. Make sure you use the proper cable type (with or without crossing of the LAN receive and transmit pairs), in accordance with the wiring requirements of your system. 2.5 Normal Indications The normal indications provided by the indicators of each HS-ETH channel are explained below. HS-ETH/B and HS-ETH/V After the power-up self-test, the LINK indicator of each module channel configured as connected must be on. When traffic flows, the RX and TX indicators light in accordance with traffic, and the COLL or ERR indicator may flash from time to time. Note If main link synchronization is lost, HS-ETH/B and HS-ETH/V modules will attempt to re-establish the link automatically. If the attempt does not succeed, the modules reset themselves (without performing the power-up self-test sequence), and continue the attempts to resynchronize. During these attempts, the LINK error indicator flashes slowly. 2-8 Normal Indications HS-ETH MP-2100/2104 Ver. 10

37 Installation and Operation Manual Chapter 2 Installation and Operation HS-ETH/F After the power-up self-test, the LINK indicator must be on. When traffic flows, the ACT indicator lights in accordance with traffic. HS-ETH/R During the power-up self-test, the ERR indicator lights steadily. After the power-up self-test, the LINK indicator of each module channel configured as connected must be on. When traffic flows, the RX and TX indicators light in accordance with traffic, and the ERR indicator must be off. If an ERR indicator flashes after power-up self-test, this indicates that the corresponding IP router uses its default IP address, and therefore it is necessary to configure its IP address in accordance with the application requirements.

39 Chapter 3 Configuration This Chapter provides information on the configuration parameters of the HS-ETH modules: Section 3.1 describes the configuration procedures applicable to all the modules (HS-ETH/B, HS-ETH/V, HS-ETH/F and HS-ETH/R) Sections 3.2 through 3.12 describe the specific management procedures of HS-ETH/R modules. These procedures include configuration, collection and display of performance data, and maintenance. 3.1 Common Configuration Procedures The configuration activities required to select the desired values of the parameters used in common by all the HS-ETH modules are performed by means of the management system used to control the Megaplex systems. The instructions appearing in this section assume that you are familiar with the management system being used: supervision terminal or Telnet (covered by the Megaplex-2100/2104 Installation and Operation Manual), or a network management system, e.g., the RADview network management system (refer to the RADview User's Manual for instructions). Channel Parameters Table 3-1 explains the user-selectable channel parameters, and their range of values. Table 3-1. Channel Parameters Parameter CONNECT Description Determines whether the channel is connected to the main link: YES Channel is connected NO Channel is disconnected. You can still program the desired parameters, so the channel will be ready for operation when needed Default: NO HS-ETH MP-2100/2104 Ver. 10 Common Configuration Procedures 3-1

40 Chapter 3 Configuration Installation and Operation Manual Parameter BUS CONNECTION Description Selects the group of TDM buses accessed by the HS-ETH module: REGULAR SPECIAL For normal operation. Module accesses TDM buses C and D. This option is used only for modules ordered with option /CD. Default: REGULAR Note: Make sure to select the correct option, in accordance with your HS-ETH version. If you select REGULAR for the modules with the /CD option, or SPECIAL for the regular HS- ETH versions, you will see Alarm 28: HARDWARE/SOFTWARE MISMATCH. RATE Selects the main link data rate to be assigned to the corresponding channel. The selected rate determines the bridge throughput. The available selections are n 56 kbps and n 64 kbps, where the allowed range of n is as follows: E1 links with G732N framing: 1 to 31 E1 links with G732S framing: 1 to 30* T1 links: 1 to 24. Default: 1 64 kbps Notes: Make sure to select rates from the same group (n 56 kbps or n 64 kbps) in each pair of channels: 1, 3 and 2, 4. The total number of timeslots that can be assigned to one pair of channels (1 and 3, or 2 and 4) cannot exceed 31. OPERATION MODE Selects the operating mode of the channel: BI-DIR Bidirectional (normal) mode. Ignore the other options. Note: Only the BI-DIR mode permits normal transmission of LAN traffic. Default: BI-DIR ML SLOT Selects the main link module to which the corresponding channel will be connected: IO-1 up to the maximum supported by chassis Default: IO-1 ML CHANNEL Selects the external port of the main link module, to which the corresponding channel will be connected: EX1 up to the maximum supported by the selected main link module. Default: EX1 MAP TYPE Selects the timeslot mapping method to the destination main link port: When using the BI-DIR mode, this field automatically changes to N/A, to remind you that the destination must be selected using the DEF TS command. Default: N/A START TS Always displays N/A Timeslot Assignment After performing the configuration of the individual module channels, it is necessary to assign main link timeslot to each connected channel, as explained in the Megaplex-2100/2104 Installation and Operation Manual. 3-2 Common Configuration Procedures HS-ETH MP-2100/2104 Ver. 10

41 Installation and Operation Manual Chapter 3 Configuration 3.2 HS-ETH/R Configuration Procedures Each IP router in the HS-ETH/R module has its own management subsystem, which supports the following functions: Preliminary configuration Configuration of management access parameters Configuration of specific router parameters Collection and display of statistical performance data Maintenance functions, which include: Software downloading Resetting of various IP router subsystems Display of IP router error log Ping utility, for checking IP connectivity. The management subsystem of each HS-ETH/R IP router is a separate, independent entity, and therefore it cannot be managed through the Megaplex management subsystem. The communication with the HS-ETH/R IP router management subsystem is made through the LAN interface connector of the corresponding channel. Passwords can be used to prevent unauthorized access. Accessing the HS-ETH/R IP Router Management Subsystem Each HS-ETH/R IP router must be configured in accordance with the specific requirements of the user s application before it can be used in the user s network. As a result, it is not possible to supply default parameters to enable an IP router to start service without any preliminary configuration. Therefore, to enable the user to establish Telnet communication and configure the HS-ETH/R IP routers, the HS-ETH/R module is delivered with a default set of parameters for its IP routers. The default parameters are automatically used: Before the IP router is configured by the user, e.g., when a new HS-ETH/R channel is put into operation After the user s configuration parameters have been erased. When the factory-default parameters are used, the ERR indicator of the corresponding channel, located on the HS-ETH/R panel, flashes rapidly (about three times per second). Note The flashing of the ERR indicator also serves as a warning to the user that the corresponding WAN interface does not send nor receive packets, and therefore the HS-ETH/R channel can be accessed only from the LAN side, through its NET connector. After configuring the IP router, it starts normal operation and routes the traffic in accordance with the user-selected configuration parameters. To change the parameters of an already-configured IP router, establish communication from a Telnet host using the assigned IP address. HS-ETH MP-2100/2104 Ver. 10 HS-ETH/R Configuration Procedures 3-3

42 Chapter 3 Configuration Installation and Operation Manual Default IP Communication Parameters The default IP communication parameters are as follows: The default IP address of each HS-ETH/R Ethernet port is , and the default IP subnet mask is The port will accept IP packets only from the IP address Therefore, as long as the factory defaults are in effect, you must assign this address to the Telnet host used to configure an HS-ETH/R channel. You can change the default parameters using the IP learning mechanism explained below. Note In the default configuration, the WAN interface of the HS-ETH/R channel is disabled. In order to enable the WAN interface, you must modify the Ethernet port address or the IP subnet mask. Rescue Configuration In case you have forgotten the IP address or the Telnet password, you will generally not be able to view or modify the IR-IP configuration. The Rescue feature allows you to overcome this problem. To allow the IR-IP configuration: 1. Remove the HS-ETH module from the chassis. 2. Set section 6 of the DIP switch to ON. 3. Insert the HS-ETH module back into the chassis. As soon as HS-ETH is powered on, it will respond to the default IP address and permit entering configuration screens without password protection. All the other configuration parameters remain unchanged. 4. After setting the parameters to desired values, remove the HS-ETH module from the chassis and restore section 6 of the DIP switch to OFF. 3.3 Preliminary Configuration The software necessary for performing all the management and configuration functions is stored in the HS-ETH/R module, and therefore you only need a regular Telnet host to perform all the HS-ETH/R IP router management activities. A Telnet host is any computer that fulfills the following minimum requirements: A standard 10BaseT Ethernet interface A TCP/IP protocol stack (which enables it to support IP communication through the Ethernet interface) Telnet client software A ping utility. 3-4 Preliminary Configuration HS-ETH MP-2100/2104 Ver. 10

43 Installation and Operation Manual Chapter 3 Configuration Outline of Preliminary Configuration Procedure To perform the preliminary configuration: 1. Connect the Telnet host to the NET connector of the desired HS-ETH/R channel. 2. Configure the Telnet host to enable communication with the HS-ETH/R channel using the default IP parameters. 3. Establish communication with HS-ETH/R channel and assign the prescribed IP address to its LAN interface. 4. Establish again communication with HS-ETH/R channel and continue the preliminary configuration as explained in the Quick Setup Menu section below. Connecting the Telnet Host Before starting the management and configuration activities, it is necessary to establish IP communication between your Telnet host and the HS-ETH/R channel. For this purpose, it is necessary to provide a communication path. Because of the method used to assign an IP address to HS-ETH/R LAN port, it is recommended to connect the Telnet host directly to the desired HS-ETH/R NET connector. This is made by connecting an Ethernet cross cable between the Ethernet connector of the Telnet host and the desired HS-ETH/R NET connector. However, you may also connect through a common LAN: in this case, connect your Telnet host and NET connector of the HS-ETH/R channel to Ethernet hub ports using straight cables. Preliminary Telnet Host Configuration To establish IP communication between your Telnet host and NET connector of the HS-ETH/R, configure the Telnet host as follows: 1. Temporarily configure the host IP address as The initial destination IP address to be used by the host is Note The first step in the preliminary configuration process is to assign the desired IP address to the LAN interface of the HS-ETH/R channel. After an IP address is assigned and saved, you must change the destination IP address of the Telnet host to the new address, otherwise it is not possible to continue the configuration process. At the same time, you can also change the temporary IP address assigned to the host ( ) back to its permanent address. If you do not know the current IP address and/or Telnet password of a module channel, you must restore the default IP address and cancel password protection before you will be able to view or modify the HS-ETH/R configuration. To restore factory default IP address for a specific channel: 1. Remove the HS-ETH/R module from the chassis. HS-ETH MP-2100/2104 Ver. 10 Preliminary Configuration 3-5

44 Chapter 3 Configuration Installation and Operation Manual 2. Set section 6 of the corresponding SW3 switch to ON. 3. Insert the HS-ETH module back into the chassis and wait at least one minute, until the ERR indicator of the corresponding channel starts flashing. 4. Remove the HS-ETH/R module from the chassis and return section 6 of the corresponding SW3 switch to OFF. After reinserting the HS-ETH/R module, you can start the configuration using the default IP address ( ). What to Do If... The ERR indicator does not light immediately after HS-ETH/R is powered up: HS-ETH/R is faulty and must be replaced. After turn-on, the ERR indicator lights for 15 seconds and then turns off. The other indicators do not light, and there is no response from the HS-ETH/R: No software loaded into HS-ETH/R. Download software using the procedure described in the New Software Download Menu section below. After turn-on, the ERR indicator lights for 15 seconds, and then turns off. RX and TX indicators light from time to time, but there is no response from HS-ETH/R: 1. No software loaded into HS-ETH/R or software is corrupted. Service is required. 2. The HS-ETH/R channel has been configured. If you do not know the current IP address of the LAN interface, follow the rescue procedure described in Rescue Configuration section above. No ping replies from HS-ETH/R channel: If your host does not begin to receive ping replies after three unsuccessful attempts, check the physical connection path between the Telnet host Ethernet interface and the HS-ETH/R channel NET connector. The IP learning process is not successful: Check that the prescribed IP address does not appear in the ARP table. 3.4 HS-ETH/R Management Utility General Operating Procedures The HS-ETH/R channels are managed via a simple, menu-driven utility that uses a basic terminal user interface. A typical screen is shown in Figure 3-1. As seen in Figure 3-1, each screen has a header that identifies the device being configured and the logical name assigned by the user, followed by the running software revision and date. The bottom line of the screen displays prompts that guide you in the execution of the various activities. 3-6 HS-ETH/R Management Utility HS-ETH MP-2100/2104 Ver. 10

Protocol :[ Frame Relay ] LAN IP Address Press one of the numbers to select or ESC: Figure 3-3. Quick Setup Menu Used to enter the IP address for the channel IP router LAN interface. This is the address to which nodes connected to the local LAN send packets addressed to the WAN through this HS-ETH/R channel. LAN IP Mask Used to enter the IP subnet mask. The IP router supports a maximum of 254 hosts on the LAN, therefore you must use Class C subnet masks. The basic subnet IP mask for Class C addresses, which supports the maximum possible number of hosts, 254, is Refer to Appendix E of the Megaplex Installation and Operation Manual for additional information regarding the selection of IP subnet masks. WAN IP Address Used to enter the IP address for the corresponding HS-ETH/R channel WAN interface, i.e., the IP address to be used by IP hosts on the WAN to reach this HS-ETH/R channel. If the WAN IP Address field remains blank, the HS-ETH/R channel operates in the Unnumbered Router Mode. WAN IP Mask Used to enter the IP subnet mask for the WAN interface of this channel.

48 Chapter 3 Configuration Installation and Operation Manual Default Gateway Operation without Default Gateway The IP routers of the HS-ETH/R module are intended to enable the extension of LANs through the Megaplex links. Therefore, their default routing operation is different from the default routing operation of standard IP routers: A HS-ETH/R channel forwards packets with destinations not located on the local LAN through the WAN interface Packets received by this channel from the WAN interface and destined to hosts located on the local LAN are forwarded to the LAN; other packets are discarded. The default operation is used when the Default Gateway field is blank. Operation with Default Gateway You can instruct the HS-ETH/R channel to send packets with destinations not located on the local LAN to a specific router, which is called the default gateway. The default gateway must be connected to the local LAN. To use this option, enter the IP address of another router attached to the local LAN in the Default Gateway field. Note It is very important to obtain the correct parameters from the system administrator or ISP. The most common problem when establishing an IP connection is incorrect configuration of IP parameters and default gateway. Do not try to guess these parameters. DHCP Server IP Address The HS-ETH/R can serve as a DHCP (Dynamic Host Control Protocol) relay for nodes attached to the local LAN. When using DHCP, the user does not need to configure IP addresses and other related parameters that can be provided by means of the DHCP protocol for the PCs on the LAN: they receive the configuration from the DHCP server whose IP address is configured in this field, via the HS-ETH/R channel. To configure the HS-ETH/R channel as a DHCP relay: Enter the IP address of the desired DHCP server in this field. Leaving this field blank disables the DHCP relay function. Read Protocol from DIP Switches Selecting YES for this parameter forces this HS-ETH/R channel to use the WAN protocol selected by section 4 of its SW3 DIP switch: PPP or Frame Relay. If you want to be able to select the WAN protocol by means of the Protocol field (parameter 7) of the Quick Setup menu, select NO Quick Setup Menu HS-ETH MP-2100/2104 Ver. 10

49 Installation and Operation Manual Chapter 3 Configuration Protocol Used to select the WAN protocol to be used by the IP router card: PPP, HDLC or Frame Relay. This parameter is available only if the Read Protocol from DIP Switches parameter is set to NO. 3.6 Management Access Menu The Management Access menu is used to enable the use of passwords to protect the access to HS-ETH/R management utility, and control the inactivity time-out interval. When password protection is enabled on a specific channel, a Telnet management session can start only after the correct password is entered.

67 Installation and Operation Manual Chapter 3 Configuration For an identification of the internal DIP switch settings, refer to Chapter 2. Note To erase the user s configuration: 1. Power the HS-ETH/R module off (either by turning the Megaplex power off, or by removing the HS-ETH/R module). 2. Set all the sections of the DIP switch SW3 of the desired HS-ETH/R channel to ON. 3. Power the HS-ETH/R up and monitor the ERR indicator of the corresponding channel: it must turn on and start flashing steadily. 4. While the ERR indicator is flashing (within 15 seconds), set sections 4 and 5 of the DIP switch to OFF. While erasing is in progress, the ERR indicator lights steadily. After the IP router configuration is erased, it starts flashing again, to indicate that the IP router uses the default IP address. If you do not set sections 4 and 5 to OFF within 15 seconds of power-up, the channel ignores the setting of all the four sections to ON and starts normal operation. In this case, it is recommended to turn the HS-ETH/R power off and then back on. To abort the whole operation, turn the HS-ETH/R power off, return all the DIP switch sections to the desired positions (see Chapter 2 for details), and then turn the HS-ETH/R power again. 5. Turn the HS-ETH/R power off, and then return all the sections of the corresponding channel DIP switch to the desired positions Erasing HS-ETH/R Software Note It is possible to erase the application software of any HS-ETH/R channel, without erasing the channel user-defined parameters. This procedure requires access to the internal switches of the desired HS-ETH/R channel, for example, by removing enough modules from the adjacent slots or by using a special extender that enables technical support personnel to operate the module, for maintenance purposes, outside the chassis. After the application software is erased, the HS-ETH/R channel starts its TFTP server application, and waits for the downloading of software by a TFTP client connected to its LAN interface. The procedure to be used to download the application software in this case is also described below. You may want to erase the application software if the downloading of new software using the Device Control menu (see Figure 3-12) fails, and the HS-ETH/R channel does not function properly.

While the ERR indicator is flashing (within 15 seconds), set sections 3 and 2 of the corresponding HS-ETH/R channel DIP switch to OFF. While erasing is in progress, the ERR indicator lights steadily. After the IP router application software is erased, the indicator turns off. Note If you do not set sections 3 and 2 to OFF within 15 seconds of power-up, the HS-ETH/R channel ignores the setting of all the sections to ON and starts normal operation. In this case, it is recommended to turn the HS-ETH/R power off and then back on. Alternately, to abort the whole operation, turn the HS-ETH/R power off, return all the switches to the desired positions, and then turn the HS-ETH/R power on again. 5. Turn the HS-ETH/R power off, and then return all the sections of the desired channel DIP switch to the desired positions. Downloading New Software After erasing the application software, you can download new software from any computer that can serve as a TFTP client. To enable the downloading, the HS-ETH/R channel automatically activates its TFTP server application with the following factory-default IP parameters: IP address: Subnet mask: Connect the computer serving as a TFTP client to the NET connector of the corresponding HS-ETH/R channel in the way as a Telnet host used for preliminary configuration (see Section 3.4). The computer IP parameters must be configured as follows: IP address Subnet mask Default gateway To download new software: 1. If necessary, turn the HS-ETH/R power off. 2. Set all the sections of the corresponding HS-ETH/R DIP channel switch to OFF. 3. Turn the HS-ETH/R power on and monitor the ERR indicator of the corresponding channel: it must be off Erasing HS-ETH/R Software HS-ETH MP-2100/2104 Ver. 10

69 Installation and Operation Manual Chapter 3 Configuration 4. Connect the computer to the channel NET connector and make sure the LINK indicator is on. Now configure the channel IP parameters as explained above. 5. Run a standard TFTP client application on the Telnet host, and download the appropriate software file. If the download is successful, the HS-ETH/R channel starts using the new software. If downloading fails, the channel starts using its default IP address, and the ERR indicator starts flashing. In this case, repeat the download process. To restore the default IP address of a channel without erasing the existing channel configuration: 1. Remove the HS-ETH/R module from the chassis. 2. Set section 6 of the corresponding SW3 switch to ON. 3. Insert the HS-ETH module back into the chassis. At this stage, the corresponding HS-ETH/R channel uses the default IP address ( ), but its previous configuration has not been erased. You can now configure the desired channel IP address, while continuing using the previous configuration. HS-ETH MP-2100/2104 Ver. 10 Erasing HS-ETH/R Software 3-31

71 Chapter 4 Troubleshooting and Diagnostics This Chapter explains the module specific tests and diagnostic functions and provides troubleshooting instructions. For information on the alarms generated by the HS-ETH modules, refer to the Megaplex-2100/2104 Installation and Operation Manual. The diagnostic information presented in this chapter supplements the general Megaplex diagnostics operation instructions contained in the Megaplex-2100/2104 Installation and Operation Manual. 4.1 Diagnostic Functions The diagnostics functions available on each HS-ETH module channel are: Local loopback Remote loopback. The following sections describe the available diagnostic activities. Caution Activating a loopback disrupts the LAN traffic, because it can lead to continuous collisions. Therefore, these functions can only be used for troubleshooting purposes, in conjunction with the main link BER test subsystem. When a loopback is activated, the user can also specify the time it remains active: the range is 1 through 30 minutes, in 1-minute steps. After the specified time, the loopback is automatically deactivated, thereby reducing the management workload during system troubleshooting. The default selection is continuous connection, that is, the loopback remain active until canceled by a user's command. Local Loopback When a local loopback is activated, the TDM bus interface of the corresponding HS-ETH channel loops back the transmit signal toward the receive input of the same channel. The transmit signal is still sent to the remote Megaplex unit. The loopback signal path is shown in Figure 4-1. HS-ETH MP-2100/2104 Ver. 10 Diagnostic Functions 4-1

72 Chapter 4 Troubleshooting and Diagnostics Installation and Operation Manual Caution As a result of the local loopback, the frames sent to the link are returned to the same interface after a relatively short delay: in general, this causes a continuous state of collision on the LAN. Collisions do not permit normal operation of the LAN, therefore the local loopback should be used carefully for limited intervals and after coordination with the LAN administrator. User or Test Equipment Channel HS-ETH I/O Modules Local Unit Remote Unit HS-ETH I/O Modules User or Test Equipment System Management Figure 4-1. Local Loopback Remote Loopback When a remote loopback is activated, the TDM bus interface of the corresponding HS-ETH channel loops back the receive signal toward the transmit input of the same channel, and therefore the received signal is returned in the same timeslots toward the remote Megaplex unit. The receive signal is still sent to the local channel interface. The loopback signal path is shown in Figure 4-2. As a result of the remote loopback, the frames received from the link are returned to their source after some delay. This loopback may therefore cause a continuous state of collision on the LAN connected to the remote channel. 4-2 Diagnostic Functions HS-ETH MP-2100/2104 Ver. 10

Remote Loopback 4.2 Recommended Test Sequence If a complaint is received from one of the local LAN users, first observe the module indications and make sure the problem is not the result of a problem in the connection of the HS-ETH module to the LAN. Also check whether the problem disappears when the HS-ETH is disconnected from the LAN: if the problem persists, it is probably not related to the HS- ETH, but to the other equipment connected to the LAN. Check the type of cable: Use a crossed Ethernet cable for connection to another station connector Use a straight Ethernet cable for connection to an Ethernet hub or switch. If the problem is related only to the communication between the local and remote LANs, check for correct configuration of both HS-ETH modules. If configuration is correct, replace the HS-ETH module.

74 Chapter 4 Troubleshooting and Diagnostics Installation and Operation Manual 4.3 Frequently Asked Questions Q How can I use all four MP buses (A, B, C and D) using an HS-ETH module? A You may use a combination of HS-ETH and HS-ETH/CD modules: HS-ETH enables connection to Bus A, B. HS-ETH/CD enables connection to Bus C, D. Q Is it possible to transfer IEEE 802.1Q IP packets with an HS-ETH module? A Yes, it is. In order to be able to transfer VLAN tagging packets you should use the HS-ETH/V module. Q Does the HS-ETH/R module support DHCP relay? A No, it does not. Q Is it possible to operate the HS-ETH module opposite other RAD Bridges (such as Webranger, FCD-IP, TinyBridge)? A Yes, it is. These modules (HS-ETH/B, HS-ETH/F, HS-ETH/V) use the same Bridging method. 4.4 Technical Support Technical support for this product can be obtained from the local distributor from whom it was purchased.
