6 Ethernet interface configuration Ethernet is the most widespread wired LAN technology due to its flexibility, simplicity, and easy implementation. Your device supports the following types of Ethernet interfaces: Layer 2 Ethernet interfaces Physical interfaces operating on the data link layer for Layer 2 packet forwarding. They can only forward packets carrying source and destination IP addresses that belong to the same network segment. Layer 3 Ethernet interfaces Physical interfaces operating on the network layer for Layer 3 packet forwarding, and forward packets carrying source and destination IP addresses that belong to different network segments. You can assign an IP address to a Layer 3 Ethernet interface. Layer 2-Layer 3 Ethernet interfaces Physical interfaces that can operate on both the data link layer and the network layer. When operating on the data link layer, a Layer 2-Layer 3 Ethernet interface acts as a Layer 2 Ethernet interface. When operating on the network layer, a Layer 2-Layer 3 Ethernet interface acts as a Layer 3 Ethernet interface. Layer 3 Ethernet subinterfaces Logical interfaces operating on the network layer. You can assign an IP address to a Layer 3 Ethernet subinterface. By creating subinterfaces on a Layer 3 Ethernet interface, you can enable the interface to carry packets for multiple VLANs, which provides great networking flexibility. Layer 3 VE interfaces Used on interface modules for carrying data link layer protocols over Ethernet. General configuration This section describes the attributes and configurations common to Layer 2 and Layer 3 Ethernet interfaces or subinterfaces. For more information about the attributes and configuration, see Configuring a Layer 2 Ethernet interface and Configuring a Layer 3 Ethernet interface or subinterface. Configuring a combo interface Introduction to Combo interfaces A Combo interface is a logical interface that comprises one optical (fiber) port and one electrical (copper) port. The two ports share one forwarding interface and cannot work simultaneously. When you enable the electrical port, the optical port is disabled automatically and vice versa. The optical and electrical ports of a Combo interface share one interface view, in which you can activate the optical or electrical port, and configure other port attributes, such as the interface rate and duplex mode. Configuration prerequisites Before you configure Combo interfaces, complete the following tasks: Find out the Combo interfaces on your device by checking the product specifications and identify the two physical interfaces that comprise each Combo interface. Use display interface to find out which port (optical or electrical) of the current Combo interface is currently active. If the output includes Media type is twisted pair, Port hardware type is 1000_BASE_T, the electrical port is active; if the output includes Media type is not sure, Port hardware type is No connector, the optical port is active. 1

7 Changing the active port of a Combo interface To change the active port of a Combo interface: 1. Enter system view. system-view 2. Enter the Ethernet interface view. 3. Activate the electrical or optical port of the Combo interface. interface interface-type interface-number combo enable { copper fiber } By default, the electrical port of a Combo interface is active. Configuring the operating mode for a 10-GE interface CAUTION: A 10-GE interface in WAN mode encapsulates Ethernet packets in SDH frames, and a 10G packet over SDH (POS) interface encapsulates PPP packets in SDH frames. However, these two types of interfaces cannot communicate with each other, because the framing formats used by them are different. A 10-GE interface works in LAN or WAN mode. In LAN mode, the 10-GE interface transmits Ethernet packets, providing access to an Ethernet network. In WAN mode, the 10-GE interface transmits SDH packets, providing access to an SDH network. In this mode, the interface only supports point-to-point connections. Introduction to J0 and J1 overhead bytes SDH frames have diversified overhead bytes, which accomplish the operation and maintenance functions such as hierarchical management of the transmission network. J0 and J1 are used to provide internetworking support between devices of different countries, regions, or vendors. The regenerator section trace byte J0 is usually set to a section access point identifier. The sending end keeps the connection with the receiving end by sending this byte repeatedly. The path trace byte J1, a byte in the high-order path overhead and usually set to a high-order path access point identifier, functions in a similar way to keep the connection with the receiving end of the path. To ensure smooth communication, the J0 and J1 bytes should be matched respectively at the sending and receiving ends. For more information about SDH and SDH overhead bytes, see relevant technical documentation. Configuration procedure To configure a 10-GE interface to operate in LAN or WAN mode: 1. Enter system view. system-view 2. Enter 10-GE interface view. 3. Configure the 10-GE interface to operate in LAN or WAN mode. interface ten-gigabitethernet interface-number port-mode { lan wan } By default, a 10-GE interface operates in LAN mode. 2

8 4. Configure the J0 or J1 byte when the 10-GE interface is operating in WAN mode. flag { j0 j1 } sdh flag-value By default, the value of the J0 and J1 bytes is 0. Flag applies only to 10-GE interfaces operating in WAN mode. Configuring basic settings of an Ethernet interface or subinterface You can set an Ethernet interface to operate in one of the following duplex modes: Full Full-duplex mode. Interfaces operating in this mode can send and receive packets simultaneously. Half Half-duplex mode. Interfaces operating in this mode cannot send and receive simultaneously. Auto Auto-negotiation mode. Interfaces operating in this mode negotiate a duplex mode with their peers. Similarly, you can set the speed of an Ethernet interface or enable it to automatically negotiate a speed with its peer. For a 100-Mbps or 1000-Mbps Layer 2 Ethernet interface, you can also set speed options for auto negotiation. The two ends can only pick a speed from the available options. For more information, see Setting speed options for auto negotiation on an Ethernet interface. To configure an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Change the description of the interface. interface interface-type interface-number description text By default, the description of an interface is in the format of interface-name Interface. For example, GigabitEthernet4/0/1 Interface. 4. Set the duplex mode. duplex { auto full half } By default, the duplex mode is full for 10-GE interfaces, and is auto for other Ethernet interfaces. Optical interfaces do not support the half keyword. 5. Set the port speed. 6. Set the intended bandwidth for the interface. speed { auto } bandwidth bandwidth-value By default, the port speed is auto. Optical interfaces do not support the 10 and 100 keywords. Configuring an Ethernet subinterface To configure an Ethernet subinterface: 3

9 7. Enter system view. system-view 8. Create an Ethernet subinterface. interface interface-type interface-number.subnumber Required. This command also leads you to Ethernet subinterface view. 9. Set the interface description. description text By default, the description of an interface is in the format of interface-name Interface. For example, GigabitEthernet1/0/1.1 Interface. You can configure IP-related settings on an Ethernet subinterface. For more information, see Layer 3 IP Services Configuration Guide. To use an Ethernet subinterface to transmit and receive packets, you must associate it with a VLAN. For the local and remote Ethernet subinterfaces to transmit traffic correctly, configure them with the same subinterface number and VLAN ID. Shutting down an Ethernet interface or subinterface CAUTION: Use this command with caution. After you shut down an Ethernet interface manually, the Ethernet interface cannot forward packets even if it is physically connected. You may need to shut down and then bring up an Ethernet interface or subinterface to activate some configuration changes, for example, the speed or duplex mode changes. To shut down an Ethernet interface or subinterface: 1. Enter system view. system-view 2. Enter Ethernet interface or subinterface view, or port group view. Enter Ethernet interface view. Enter port group view. Enter Ethernet subinterface view. interface interface-type interface-number port-group manual port-group-name interface interface-type interface-number.subnumber Use any command. To shut down an Ethernet interface or subinterface, enter Ethernet interface or subinterface view. To shut down all Ethernet interfaces in a port group, enter port group view. 3. Shut down the Ethernet interface or subinterface. shutdown Required. By default, Ethernet interfaces and subinterfaces are up. 4

10 Configuring physical state change suppression on an Ethernet interface The physical link state of an Ethernet interface is either up or down. Each time the physical link of a port goes up or comes down, the physical layer reports the change to the upper layers, and the upper layers handle the change, resulting in increased overhead. To prevent physical link flapping from affecting system performance, configure physical state change suppression to delay the reporting of physical link state changes. The physical layer only reports the changes when the delay expires. To configure physical state change suppression on an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Set a physical state change suppression interval. interface interface-type interface-number link-delay delay-time Required. Disabled by default. Configuring loopback testing on an Ethernet interface If an Ethernet interface does not work normally, you can enable loopback testing on it to identify the problem. Loopback testing has the following types: Internal loopback testing Tests all on-chip functions related to Ethernet interfaces. External loopback testing Tests hardware of Ethernet interfaces. To perform external loopback testing on an Ethernet interface, connect a loopback plug to the Ethernet interface. The device sends test packets out the interface, which are expected to loop over the plug and back to the interface. If the interface fails to receive any test packet, the hardware of the interface is faulty. An Ethernet interface in a loopback test does not forward data traffic. To enable loopback testing on an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. interface interface-type interface-number 3. Enable loopback testing. loopback { external internal } Disabled by default. On an interface that is physically down, you can only perform internal loopback testing. On an interface administratively shut down, you can perform neither internal nor external loopback testing. The speed, duplex, mdi, and shutdown commands are unavailable during loopback testing. During loopback testing, an Ethernet interface works in full duplex mode. When you disable loopback testing, the duplex configuration of the interface restores. Configuring the link mode of an Ethernet interface 5

11 CAUTION: After you change the link mode of an Ethernet interface, all settings of the Ethernet interface are restored to their defaults under the new link mode. The link mode configuration for an Ethernet interface in system view and in interface view supersedes each other. This feature is only supported on the SAP high-density Ethernet cards. Depending on the hardware structure of interface cards, for a device, some interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode), some can operate only as Layer 3 Ethernet interfaces (in route mode), but others can operate either as Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route). To change the link mode of an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. interface interface-type interface-number 3. Change the link mode of Ethernet interfaces. port link-mode { bridge route } Required. Enabling subinterface rate statistics collection on an Ethernet interface After you enable subinterface rate statistics collection on an Ethernet interface, the device periodically refreshes the rate statistics on the subinterfaces of this Ethernet interface. You can use display interface to view the rate statistics. To enable subinterface rate statistics collection on an Ethernet subinterface: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Enable subinterface rate statistics collection on the Ethernet interface. interface interface-type interface-number sub-interface rate-statistic Disabled by default. Use this function with caution, because it may consume a large amount of system resources. Configuring a Layer 2 Ethernet interface The functions in this section apply to only routers configured with SAP modules. Layer 2 Ethernet interface configuration task list Complete these tasks to configure an Ethernet interface operating in bridge mode: Task Configuring a port group Remarks Applicable to Layer 2 Ethernet interfaces. 6

12 Task Setting speed options for auto negotiation on an Ethernet interface This function is available only for 100-Mbps or 1000-Mbps Layer 2 Ethernet interfaces that support speed auto negotiation. For a Combo interface, only the electrical port supports this function. Speed and speed auto supersede each other, and whichever is configured last takes effect.

Applicable to Layer 2 Ethernet interfaces. Applicable to Layer 2 Ethernet interfaces. Configuring a port group Some interfaces on your device may use the same set of settings. To configure these interfaces in bulk rather than one by one, you can assign them to a port group. You create port groups manually. All settings made for a port group apply to all member ports of the group. For example, you can configure a traffic suppression threshold (see This function is available only for 100-Mbps or 1000-Mbps Layer 2 Ethernet interfaces that support speed auto negotiation. For a Combo interface, only the electrical port supports this function. Speed and speed auto supersede each other, and whichever is configured last takes effect. Configuring storm suppression ) for multiple interfaces in bulk by assigning these interfaces to a port group. Even though the settings are made on the port group, they are saved on an interface basis rather than on a port group basis. You can only view the settings in the view of each interface by use display current-configuration or display this. To configure a manual port group: 1. Enter system view. system-view 2. Create a manual port group and enter manual port group view. port-group manual port-group-name Required. 7

13 3. Assign Ethernet interfaces to the manual port group. group-member interface-list Required. If you use group-member interface-type interface-start-number to interface-type interface-end-number to add multiple ports in batch to the specified port group, make sure that all these ports are of the same type and on the same interface card, and the interface-end-number argument must be greater than the interface-start-number argument. Setting speed options for auto negotiation on an Ethernet interface Speed auto negotiation enables an Ethernet interface to negotiate with its peer for the highest speed supported by both ends by default. You can narrow down the speed option list for negotiation. Figure 1 Speed auto negotiation application scenario IP network GE1/0/4 GE1/0/1 GE1/0/3 ( Speed 1000 Mbps ) ( Speed 1000 Mbps ) GE1/0/2 ( Speed 1000 Mbps ) Server 1 Server 2 Server 3 As shown in Figure 1, all ports on the switch are operating in speed auto negotiation mode, with the highest speed of 1000 Mbps. If the transmission rate of each server in the server cluster is 1000 Mbps, their total transmission rate exceeds the capability of port GigabitEthernet 1/0/4, the port providing access to the Internet for the servers. To avoid congestion on GigabitEthernet 1/0/4, set 100 Mbps as the only option available for speed negotiation on port GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3. As a result, the transmission rate on each port connected to a server is limited to 100 Mbps. To set speed options for auto negotiation on an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Set speed options for auto negotiation. interface interface-type interface-number speed auto [ ] * 8

14 This function is available only for 100-Mbps or 1000-Mbps Layer 2 Ethernet interfaces that support speed auto negotiation. For a Combo interface, only the electrical port supports this function. Speed and speed auto supersede each other, and whichever is configured last takes effect. Configuring storm suppression You can use the storm suppression function to limit the size of a particular type of traffic (broadcast, multicast, or unknown unicast traffic) on a per-interface basis in Ethernet interface view or port group view. In interface or port group view, set the maximum size of broadcast, multicast or unknown unicast traffic allowed to pass through an interface or each interface in a port group. When the broadcast, multicast, or unknown unicast traffic on the interface exceeds this threshold, the system discards packets until the traffic drops below this threshold. The storm suppression thresholds configured for an Ethernet interface may become invalid if you enable the storm control function for the interface. For information about the storm control function, see Configuring storm control on an Ethernet interface. To set storm suppression thresholds on one or multiple Ethernet interfaces: 1. Enter system view. system-view 2. Enter Ethernet interface view or port group view. Enter Ethernet interface view. Enter port group view. interface interface-type interface-number port-group manual port-group-name Use either command. To configure storm suppression on an Ethernet interface, enter Ethernet interface view. To configure storm suppression on a group of Ethernet interfaces, enter port group view. 3. Set the broadcast suppression threshold ratio. 4. Set the multicast suppression threshold ratio. 5. Set the unknown unicast suppression threshold ratio. broadcast-suppression { ratio pps max-pps kbps max-kbps } multicast-suppression { ratio pps max-pps kbps max-kbps } unicast-suppression { ratio pps max-pps kbps max-kbps } By default, broadcast traffic is not suppressed. By default, multicast traffic is not suppressed. By default, unknown unicast traffic is not suppressed. For an Ethernet interface that belongs to a port group, if you set a traffic suppression threshold for the interface in both Ethernet interface view and port group view, the threshold configured last takes effect. Configuring jumbo frame support An Ethernet interface may receive some frames larger than the standard Ethernet frame size (called "jumbo frames") during high-throughput data exchanges such as file transfers. Usually, an Ethernet interface discards jumbo frames. With jumbo frame support enabled, the interface can process frames larger than the standard Ethernet frame size yet within the specified range. In interface configuration mode (Ethernet interface view or port group view), you can set the length of jumbo frames that are allowed to pass through the Ethernet interface. 9

15 If you execute the command in Ethernet interface view, the configuration only takes effect on the current interface. If you execute the command in port group view, the configuration takes effect on all ports in the port group. To configure jumbo frame support in interface view or port group view: 1. Enter system view. system-view 2. Configure jumbo frame support. In port group view. In Ethernet interface view. port-group manual port-group-name jumboframe enable [ value ] interface interface-type interface-number jumboframe enable [ value ] Use either approach. By default, the device allows jumbo frames within the specified length to pass through all Layer 2 Ethernet interfaces. Enabling loopback detection on an Ethernet interface If a device receives a packet that it sent out, a loop has occurred to the device. Loops may cause broadcast storms, which degrade network performance. You can use this feature to detect whether a loop has occurred. Single-port loopback occurs when an interface receives a packet that it sent out and the receiving interface is the same as the sending interface, as shown in Figure 2. Figure 2 Single-port loopback Port 1 LAN You can enable loopback detection to detect loops on an interface and, if the interface supports loopback-detection action, configure the protective action to take on the receiving interface when a loop is detected, for example, to shut down the interface. Depending on whether a protective action is configured, the device takes the actions in Table 1 to alleviate the impact of the loop condition. Table 1 Actions to take upon detection of a loop condition Port type Access port Actions No protective action is configured Place the receiving interface in controlled mode. The interface discards all incoming packets, but still forwards outgoing packets. Generate traps. Delete all MAC address entries of the interface. A protective action is configured Perform the configured protective action. Generate traps and log messages. Delete all MAC address entries of the interface. 10

16 Port type Hybrid or trunk port Actions No protective action is configured Generate traps. If loopback detection control is enabled, place the receiving interface in controlled mode. The interface discards all incoming packets, but still forwards outgoing packets. Delete all MAC address entries of the interface. A protective action is configured Create traps and log messages. If loopback detection control is enabled, take the configured protective action on the interface. Delete all MAC address entries of the interface. To configure loopback detection: 1. Enter system view. system-view 2. Enable global loopback detection. 3. Set the loopback detection interval. loopback-detection enable loopback-detection interval-time time Required. Disabled by default. 30 seconds by default. 4. Enter Ethernet interface view or port group view. Enter Ethernet interface view. Enter port group view. interface interface-type interface-number port-group manual port-group-name Use either command To configure loopback detection on one interface, enter Ethernet interface view. To configure loopback detection on a group of Ethernet interfaces, enter port group view. 5. Enable loopback detection on the interface. 6. Enable loopback detection control on a trunk port or a hybrid port. 7. Enable loopback detection in all VLANs on the trunk or hybrid port. 8. Set the protective action to take on the interface when a loop is detected. loopback-detection enable loopback-detection control enable loopback-detection per-vlan enable loopback-detection action { block no-learning semi-block shutdown } Required. Disabled by default. Disabled by default. By default, a trunk or hybrid port performs loopback detection only in its default VLAN. With the shutdown keyword specified, the looped port automatically shuts down and its physical state changes to Loop down. After the loop is removed, you must run undo shutdown on the port to recover its forwarding capability. To use loopback detection on an Ethernet interface, you must enable the function both globally and on the interface. To disable loopback detection on all interfaces, run undo loopback-detection enable in system view. To enable a hybrid or trunk port to take the administratively specified protective action, you must perform loopback-detection control enable on the port. 11

17 When you change the link type of an Ethernet interface with port link-type, the switch removes the protective action configured on the interface. Setting the MDI mode of an Ethernet interface Optical interfaces do not support the MDI mode setting. You can use both crossover and straight-through Ethernet cables to connect copper Ethernet interfaces. To accommodate these two types of cables, a copper Ethernet interface can operate in one of the following MDI modes: Across mode Normal mode Auto mode A copper Ethernet interface uses an RJ-45 connector, which comprises eight pins, each playing a dedicated role. For example, pins 1 and 2 transmit signals, and pins 3 and 6 receive signals. The pin role varies by the following MDI modes: In normal mode, pins 1 and 2 are transmit pins, and pins 3 and 6 are receive pins. In across mode, pins 1 and 2 are receive pins, and pins 3 and 6 are transmit pins. In auto mode, the interface negotiates pin roles with its peer. To enable the interface to communicate with its peer, make sure that its transmit pins are connected to the remote receive pins. If the interface can detect the connection cable type, set the interface in auto MDI mode. If not, set its MDI mode using the following guidelines: When a straight-through cable is used, set the interface to work in the MDI mode different than its peer. When a crossover cable is used, set the interface to work in the same MDI mode as its peer, or set either end to work in auto mode. To set the MDI mode of an Ethernet interface: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Set the MDI mode of the Ethernet interface. interface interface-type interface-number mdi { across auto normal } By default, a copper Ethernet interface operates in auto mode to negotiate pin roles with its peer. Testing the cable connection of an Ethernet interface Optical interfaces do not support this feature. If the link of an Ethernet port is up, testing its cable connection causes the link to come down and then go up. You can test the cable connection of an Ethernet interface for a short or open circuit. The device displays cable test results within five seconds. If any fault is detected, the test results include the length of the faulty cable segment. To test the cable connection of an Ethernet interface: 12

18 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Test the cable connected to the Ethernet interface. interface interface-type interface-number virtual-cable-test Required. Configuring storm control on an Ethernet interface CAUTION: Alternatively, you can configure the storm suppression function to control a specific type of traffic. Do not enable them both on an Ethernet interface at the same time because the storm suppression and storm control functions are mutually exclusive. For example, with an unknown unicast suppression threshold set on an Ethernet interface, do not enable storm control for unknown unicast traffic on the interface. For more information about storm suppression, see This function is available only for 100-Mbps or 1000-Mbps Layer 2 Ethernet interfaces that support speed auto negotiation. For a Combo interface, only the electrical port supports this function. Speed and speed auto supersede each other, and whichever is configured last takes effect. Configuring storm suppression. Storm control compares broadcast, multicast, and unknown unicast traffic regularly with their respective traffic thresholds on an Ethernet interface. For each type of traffic, storm control provides a lower threshold and a higher threshold. For management purposes, you can configure the interface to send threshold event traps and log messages when monitored traffic exceeds the upper threshold or falls below the lower threshold from the upper threshold. When a particular type of traffic exceeds its upper threshold, the interface does either of the following, depending on your configuration: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected dropping below the lower threshold, the port begins to forward the traffic. Shuts down automatically. The interface shuts down automatically and stops forwarding any traffic. When the blocked traffic is detected dropping below the lower threshold, the port does not forward the traffic. To bring up the interface, perform undo shutdown or disable the storm control function. To configure storm control on an Ethernet interface: 1. Enter system view. system-view 2. Set the traffic polling interval of the storm control module. 3. Enter Ethernet interface view. storm-constrain interval seconds interface interface-type interface-number 10 seconds by default. 13

19 4. Enable storm control, and set the lower and upper thresholds for broadcast, multicast, or unknown unicast traffic. 5. Set the control action to take when monitored traffic exceeds the upper threshold. storm-constrain { broadcast multicast unicast } { pps kbps ratio } max-pps-values min-pps-values storm-constrain control { block shutdown } Required. Disabled by default. Disabled by default. 6. Enable the interface to send storm control threshold event traps. 7. Enable the interface to log storm control threshold events. storm-constrain enable trap storm-constrain enable log By default, the interface sends traps when monitored traffic exceeds the upper threshold or drops below the lower threshold from the upper threshold. By default, the interface outputs log messages when monitored traffic exceeds the upper threshold or falls below the lower threshold from the upper threshold. For network stability, use the default or set a higher traffic polling interval. Storm control uses a complete polling cycle to collect traffic data, and analyzes the data in the next cycle. It takes a port at least one polling interval and at most two polling intervals to take a storm control action. The storm control function allows you to set the upper and lower thresholds for all three types of packets respectively on the same interface. Configuring a Layer 3 Ethernet interface or subinterface Complete these tasks to configure Layer 3 Ethernet interfaces or subinterfaces: Task Setting the MTU for an Ethernet interface or subinterface Configuring an Ethernet interface to operate in promiscuous mode Remarks Applicable to Layer 3 Ethernet interfaces and subinterfaces. Applicable to Layer 3 Ethernet interfaces. Setting the MTU for an Ethernet interface or subinterface The value of MTU affects the fragmentation and re-assembly of IP packets. To set the MTU for an Ethernet interface or subinterface: 1. Enter system view. system-view 14

20 2. Enter Ethernet interface or subinterface view, interface interface-type { interface-number interface-number.subnumber } 3. Set the MTU, mtu size 1500 bytes by default. Due to the QoS queue length limit (for example, the default length of an FIFO queue is 75), too small an MTU results in too many fragments, which is discarded from the QoS queue. You can increase MTU or QoS queue length properly. In Ethernet interface view, you can use qos fifo queue-length to change the QoS queue length. For more information, see ACL and QoS Configuration Guide. Configuring an Ethernet interface to operate in promiscuous mode An Ethernet interface usually receives only packets with matched destination MAC addresses. After you configure an Ethernet interface to operate in promiscuous mode, however, the interface no longer checks the MAC addresses in received packets. Rather, it receives all Ethernet packets with correct format. You may need to configure a network listening port to operate in promiscuous mode. To configure an Ethernet interface to operate in promiscuous mode: 1. Enter system view. system-view 2. Enter Ethernet interface view. 3. Configure the Ethernet interface to operate in promiscuous mode. interface interface-type interface-number promiscuous Required. By default, an Ethernet interface does not operate in promiscuous mode. Configuring a VE interface VE interfaces are logical Layer 3 Virtual-Ethernet interfaces mainly used for PPPoEoA, IPoEoA and EoA. The PPPoEoA uses a three-layer architecture: PPP at the top, PPPoE in the middle, and PPPoE over ATM at the bottom, where the parameters for PPPoE are configured on Layer 3 VE interfaces on interface modules of the access device. For more information, see Layer 2 WAN Configuration Guide. IPoEoA and EoA carry Ethernet packets over ATM by binding VE interfaces to PVCs. IPoEoA is for Layer 3 VE interface binding, and EoA is for Layer 2 VE interface binding. For more information, see Layer 2 WAN Configuration Guide. The Layer 3 VE interfaces can terminate VLAN-tagged packets. 15

21 Configuration procedure When implementing PPPoEoA, IPoEoA, and EoA through a PVC, you must associate the PVC with a VE interface. Otherwise, you cannot configure the PVC. To configure a Layer 3 VE interface: 1. Enter system view. system-view 2. Create a Layer 3 VE interface and enter Layer 3 VE interface view. interface virtual-ethernet { interface-number } Required. If the specified Layer 3 VE interface already exists, you directly enter Layer 3 VE interface view. Displaying and maintaining an Ethernet interface Task Command Remarks Display Ethernet interface or subinterface information. Display traffic statistics for the specified interfaces.

23 ATM interface configuration ATM is a backbone network technology for transmission of audio, video, and data. By virtue of its flexibility and support for multimedia services, ATM is regarded as a core technology for implementing broadband communications. The ATM physical layer lies at the bottom of the ATM reference model. Though it involves specific transmission media, its functionality does not rely on the transmission mechanism and speed of a specific medium. Rather, it primarily delivers valid cells and the associated timing signals between the upper layer and transmission medium. The speeds of physical access media are defined in international standards such as ATM OC-3c/STM-1, and ATM E3/T3. ATM interfaces available on the low-end and mid-range routers The low-end and mid-range routers can provide the following ATM interfaces: ATM-E1/T1 ATM OC-3c/STM-1 based on SONET/SDH These interfaces support IPoA, IPoEoA, PPPoA, and PPPoEoA. For more information about them, see ATM configuration in Layer 2 WAN Configuration Guide. ATM interface features The ATM interfaces of low-end and middle-range routers support the following: Nonreal-time variable bit rate (nrt_vbr) Real-time variable bit rate (rt_vbr) Constant bit rate (CBR) Unspecified bit rate (UBR) Permanent virtual circuit (PVC) Per-VC traffic shaping User-to-network Interface (UNI) RFC1483 Multiprotocol Encapsulation over ATM Adaptation Layer 5 RFC2225, Classical IP and ARP over ATM RFC2390, Inverse Address Resolution Protocol F5 end to end loopback OAM ATM adaptation layer 5 (AAL5) ATM-E1/T1 interface configuration This section describes the physical configuration of ATM E1/T1 interface. For more information (including the configuration of PVCs), see Layer 2 WAN Configuration Guide. 18

24 Configuring an ATM E1/T1 interface To configure an ATM E1/T1 interface: 1. Enter system view. system-view 2. Enter ATM E1/T1 interface view. interface atm interface-number Required. 3. Set the clock mode. clock { master slave } Slave by default. 4. Set the framing format. On an E1 interface On a T1 interface frame-format { crc4-adm no-crc4-adm } frame-format { esf-adm sf-adm } CRC4 ADM by default. ESF ADM by default. 5. Set the line coding format. On an E1 interface On an T1 interface code { ami hdb3 } code { ami b8zs } HDB3 by default. B8ZS by default. 6. Enable scrambling. scramble 7. Set the cable mode. cable { long short } 8. Set the intended bandwidth for the ATM E1/T1 interface. bandwidth bandwidth-value Enabled by default. The default cable mode is long. In this mode, the system automatically adapts the cable mode to the cable actually connected. 9. Set the loopback mode. loopback { cell local payload remote } Disabled by default. E1 configurations are supported on the IMA (E1) interface module and T1 configurations on the IMA (T1) interface module. Troubleshooting ATM-E1/T1 interfaces You can start troubleshooting an ATM interface by testing network connectivity using ping or extended ping. In extended ping, specify some options in the IP header. For more information about ping, see Network Management and Monitoring Configuration Guide. If the interface cannot be pinged, check whether: The interface is down. The AAL5 encapsulation type of the PVC is incorrect. 19

25 ATM OC-3c/STM-1 interface configuration This section covers only the physical configurations of the interface. For more information about how to configure ATM (including PVCs), see Layer 2 WAN Configuration Guide. Configuring an ATM OC-3c/STM-1 interface To configure an ATM OC-3c/STM-1 interface: 1. Enter system view. system-view 2. Enter ATM OC-3c/STM-1 interface view. interface atm interface-number Required. 3. Set the clock mode. clock { master slave } 4. Set the framing format. frame-format { sdh sonet } 5. Enable scrambling. scramble 6. Set the loopback mode. loopback { cell local remote } 7. Set the intended bandwidth for the ATM OC-3c/STM-1 interface. bandwidth bandwidth-value Slave by default. SDH STM-1 format by default. Enabled by default. Disabled by default. Displaying and maintaining ATM interfaces Task Command Remarks Display information about a specified or all ATM interfaces. display interface [ atm ] [ brief [ down ] ] [ { begin exclude include } regular-expression ] display interface atm interface-number [ brief ] [ { begin exclude include } regular-expression ] Available in any view Clear the statistics on all PVCs on a specified ATM interface. Clear the statistics on an ATM interface. reset atm interface [ atm interface-number ] reset counters interface [ atm [ interface-number ] ] Available in user view Available in user view For those physical interfaces that are not connected to cables, shut down them using shutdown to avoid anomalies resulted from interference. Troubleshooting ATM interfaces When diagnosing ATM interface problems, first test the interface with ping or extended ping. 20

26 Ping can test network connectivity. Extended ping can be used to specify some options in the IP header in addition to that function. For more information about ping, see Network Management and Monitoring Configuration Guide. If the interface cannot be pinged, check whether: The interface is down, which causes missing of its route in the routing table. The AAL5 encapsulation of the PVC is incorrect (only for 155 Mbps ATM interfaces). 21

27 WAN interface configuration In terms of line type, WANs fall into these types: X.25, FR, and ATM. To interface to these networks, routers are designed with the asynchronous serial interface, synchronous serial interface, ATM interface, CE1 interface, and so on. The A6600 routers support the serial interfaces, CE1 interfaces, CT1 interfaces, CE3 interfaces, and CT3 interfaces. Synchronous serial interface A synchronous serial interface has the following features: Works in either DTE or DCE mode. Usually, it serves as DTE to accept the clock provided by DCE. Is connected by various types of cables, such as V.24, V.35, X.21, RS449, and RS530. Your router can automatically detect the type of connected cables and select electrical properties. In most cases, you do not need to manually configure them. Supports link layer protocols such as PPP and FR. Supports network layer protocols IP and IPX. Provides information about the connected cable type, operating mode (DTE or DCE), and so on after you run display interface serial. Configuring a synchronous serial interface To configure a synchronous serial interface: 1. Enter system view. system-view 2. Enter serial interface view. interface serial interface-number 3. Set the link layer protocol. link-protocol { fr hdlc ppp } The default is PPP. 4. Set the digital signal coding format. 5. Set the baud rate. code { nrz nrzi } baudrate baudrate virtualbaudrate virtualbaudrate The default is non-return-to-zero (NRZ). The default is 64,000 bps. These commands are only available to synchronous/asynchronous serial interface operating in asynchronous mode. 6. Set the clock On DTE side clock { dteclk1 dteclk2 dteclk3 dteclk4 dteclkauto } 22
