Each device includes various instructions/information regarding the following fields: installation (including technical data), operation.! Please note the instructions for both fields in particular the safety instructions included with the installation instructions of the devices. Intended use Switch 6+2-Port 100 DATALIGHT has different operating modes and functionalities. Among other things, it can be used as a connection to the overriding network level or as a distributor in the internal network. Never use the device for any other purposes. Only operate it in dry indoor rooms and in the permissible ambient temperatures. General information The switch provides an excellent opportunity to meet the requirements of modern network infrastructures in accordance with DIN and RAL- RG 678 without having to go without the flexible use of modern technologies, e.g., IP telephony or IP TV. The switch works like a conventional manageable Ethernet switch with RJ45 outlets for conventional data terminals (1000 Mbps data rate). The voltage is supplied via the included 230 V power supply unit. The switch is connected to the individual DATALIGHT access points via polymer optical fibres (POF). Additionally, the switch can be connected to devices such as routers, modems or others using patch cables, and features extensive configuration options. System requirements LAN connection via POF cable or patch cable PC/laptop with network card and internet browser 3

4 1 Function Switch 6+2-Port 100 DATALIGHT can be configured via a web-based user interface, for example, Internet Explorer, Firefox, Safari or another web browser. It provides the user with an interface to define the administrator, port management, VLAN, per port counter, trunk setting, QoS setting, security filter, configuration/backup/ recovery, log-out, etc. To log in to Switch 6+2-Port 100 DATA- LIGHT, first make sure that your device is in the same IP level ( xxx). You can then select the user interface by entering the IP address displayed on the right in the address line of the browser. Default IP address: Default user name (ID): admin Default password: system NB Please be aware that user name and password are case-sensitive. If you enter an incorrect user name and/ or password, an error message appears. NB The user interface is designed for a 24+2-port switch. With Switch 6+2- Port 100 DATALIGHT, only ports 1 6 as well as 25 and 26 are available! 4

5 2 Administrator 2.1 Authentication Configuration This page allows the user to change the user name and password. The characters allowed for these fields are a-z, A-Z, 0-9, _, +, -, =. Both fields allow a maximum of 15 characters. 2.2 System IP Configuration This page shows the system configuration including the currently used IP address, subnet mask and gateway. The user can configure IP address, subnet mask and gateway via the System IP Configuration page. With the DHCP method, the smart switch also offers the possibility to assign dynamic IP addresses. Click Update to save the changes. Then click Reboot to apply the updated settings. If the IP address has been changed, you can access the page by entering the new IP address. NB Note the changed IP in the manual to ensure access to the switch at a later point in time! 5

6 2 Administrator 2.3 System Status Here you can check the status of the switch as well as the MAC address and the software version. The Comment field allows the network administrator to define a name for this switch. a-z, A-Z, _, +, -, 0-9 are possible characters, special characters are not. If you want to change the MAC address of this switch, enter MACIDFix.htm following the IP address in the address line of the browser. Example: Please note that this page is case-sensitive. The name of the page should be exactly the same as the link shown on the right. 2.4 Load Default Setting Click the Load button to reset the switch to its default settings. Note: This change affects the behaviour of the switch only, not the change of the user name, password and IP configuration. Once the reset has been executed, all settings are reset to their default value. 6

7 2 Administrator 2.5 Firmware Update Before you can update the firmware, enter the password twice and then click Update. The switch will now delete the flash memory. A safety mechanism keeps the boot system intact. Even if the power supply or the connection is interrupted during the update process, the boot system can restore the code for the firmware update page. Clicking the Update button deletes the old webcode. After completing the process, you must select the image file and click the Update button for activation. 2.6 Reboot Device You can reboot the switch here. Click Confirm to shut down and then restart the switch. 7

8 3 Port Management 3.1 Port Configuration On this page, you can make settings for the transfer mode of the physical ports. Click Update after making the settings. The settings are now displayed in the status window. 3.2 Port Mirroring Port mirroring can be executed by adjusting the following functions: a) Destination Port: The Destination Port is the physical port which copies the data from the Source Port. It is theoretically possible to select more than one Destination Port in the network. In fact, the port mirroring feature shall decrease traffic in the network; therefore, we recommend selecting one Destination Port only. b) Monitored Packets: n Disable: means the feature is not enabled. n Rx: means copying the incoming packets from the Source Port and forwarding them to the specified Destination Port. n Tx: means copying the outgoing packets from the Source Port and forwarding them to the specified Destination Port. n Rx & Tx: is the combination of Rx and Tx. c) Source Port: The data source copied to the Destination Port. Take the following configuration as an example: Source Port: Port 1 ~ Port 4 Destination Port: Port 5 ~ Port 6 Mirrored Packet: RX This means that all packets received in Port 1-4 are copied to Port 5 and 6. 8

9 3 Port Management Caution The more Source and Destination Ports you set, the less throughput is available in the network for normal traffic! 3.3 Bandwidth Control Here you can make the bandwidth settings per port. The Tx and Rx rate can be filled with a number between 1 and 255. This number should be multiplied with the selected bandwidth resolution to show the actual bandwidth. Example: The Tx numbers of ports 1~4 are set to 10, 20, 30, 40 and the speed base is set to low. The actual bandwidth is calculated as follows: 32 Kbps * 10, 32 Kbps * 20, 32 Kbps * 30 or 32 Kbps * 40. After the page has been updated, the actual bandwidth is displayed in the Tx field. Restriction of bandwidth control n If the bandwidth has been set to high, the bandwidth setting for 100 Mbps cable speed should be lower than 196. n If you set the bandwidth to 0, the switch is running at full speed. If the bandwidth setting has been set higher than the maximum speed (100 Mbps), an error message appears. 9

10 3 Port Management 3.4 Broadcast Storm Control Broadcast Storm Control is used to block the excess broadcast packets. The valid range is between 1 and 63. The broadcast packet is only checked at the selected port and the number of broadcast packets is counted in each time unit. A time unit is 5000 µs for 10 Mbps speed, 500 µs for 100 Mbps and 50 µs for 1 Gbps. The excess broadcast packet is discarded. Broadcast packets sent from a non-selected port will be treated as normal traffic by the switch. Example: Broadcast Storm of ports 1 to 6 has been enabled and the threshold value has been set to 10. The broadcast packets will be discarded if the number of packets exceeds the threshold. 10

11 4 VLAN Setting 4.1 VLAN Mode The smart switch supports two VLAN modes: tag-based and port-based. However, only one VLAN mode can be enabled. If tag-based VLAN is enabled, the user can define the treatment method of a VLAN tag for the specified port ( add a VLAN tag, remove a VLAN tag or don t care ). 4.2 VLAN Member Port-based VLAN Member The port-based VLAN is configured from the point of the physical port. Each port should be mapped onto a VLAN entry. Operating sequences: 1) Select a port number and click Read. The Port Member is now displayed in the table. You can reassign the VLAN Member for this port. 2) First, select a port number and then the VLAN Member. Click the Update button for the changes to take effect. 3) Click Load Default to reset the default settings for this port. The default settings select all 8 ports as member of this VLAN. 11

12 4 VLAN Setting Tag-based VLAN There are 3 options for each port on the first page. Add Tag: The outgoing packet should include a VLAN tag regardless of whether a VLAN tag has been received at the source port. Don t care: The outgoing packet remains unchanged regardless of whether a VLAN tag has been received at the source port. Remove Tag: The VLAN tag is removed from the outgoing packet regardless of whether a VLAN tag has been received at the source port. Now click Update to save the changes. On the second page, the user must define the VLAN Member and the VID. The VLAN table is built up depending on the specification of VLAN ID, VLAN number and VLAN index. Note: VLAN number = Index+1 Follow the procedure below to set the VLAN table. 1) Select the VLAN number 2) Complete VID 3) Complete index for each port 4) Click Update 12

13 4 VLAN Setting The VLAN table looks as follows after updating: Network situation Case 1: If the packet arriving at port 6 includes a VID = 20, the outgoing packet is forwarded to port 1~4. The VLAN Member for VID = 20 is port 1~4 P1 P2 P3 P4 P5 P6 13

14 4 VLAN Setting Case 2: If the packet arriving at port 5 includes a VID = 12, the packet is dropped from the point in time when VID = 12 has not been defined in the VLAN table. This packet is discarded from the point in time when no VLAN entry includes VID = 12. P1 P2 P3 P4 P5 P6 The arriving packet includes a VID = 12 14

15 4 VLAN Setting Case 3: If the packet arriving at P5 includes a VID = 20, the packet is forwarded to P1~P4 according to the VLAN table. The VLAN tag of each outgoing packet is assigned as shown in the figure below. The tag from the outgoing packet is removed since the action of the port has been set to remove tag. P1 P2 P3 P4 P5 P6 The VID = 20 from the arriving packet is maintained since the port s action has been set to add tag. The arriving packet includes a VID = 20. The outgoing and incoming packet remains the same since the action of the port has been set to don t care. The tag of the outgoing packet is removed since the action of the port has been set to remove tag. 15

16 4 VLAN Setting Case 4: P3 and P5 have been set to 20. If the packet arriving at port 3 does not include a VID, the switch will automatically insert one. If the incoming transfer packet from port 3 does not include a VID, the switch will automatically insert a VID = 20 into this packet. P1 P2 P3 P4 P5 P6 A VLAN tag (VID = 20) has been added automatically to the outgoing packet since the action of this port has been set to don't care. The outgoing packet will be the same as the one received since the action of the port has been set to don t care. The tag of the outgoing packet is removed since the action of the port has been set to remove tag. 16

17 4 VLAN Setting 4.3 Multi to 1 Setting Multi to 1 VLAN is used in CPE in addition to Ethernet-to-the-home and is exclusively available with the VLAN member setting VLAN setting. If the VLAN member setting has been updated, the multi to 1 setting becomes ineffective and vice versa. The disabled port equals the port that was excluded in this setting. All ports excluded in this setting are treated as the same VLAN groups. 17

18 5 Per Port Counter This page provides the port counter for each port. There is a total of 4 types of statistics. These 4 categories do not function simultaneously. The counter will be reset as soon as you change the counter category. Transmit Packet & collision: This category displays the packets transmitted from the switch and the number of collisions. Receive Packet & Transmit Packet: This category also displays the number of packets received (except for faulty packets) and the number of transmitted packets. Receive Packet & Drop Packet: This category displays the number of valid packets received and the number of discarded packets. Receive Packet & CRC Packet: This category displays the correctly received packets and the received CRC error. Refresh: After clicking the Refresh button, the numbers of the counters for all ports are summarized. Clear: Click Clear to reset all counters. 18

19 6 QoS Setting 6.1 Priority Mode On this page, you can set the planning mode for the Tx packets on each port. All-high-before-Low (strict priority): All packets are either assigned to the high priority queue (queue 2) or the low priority queue (queue 1). A packet from queue 1 is only forwarded as soon as the high priority queue is empty. WRR mode There are 4 priority queues for the Weight-Round-Robin (WRR) mode. When this mode is selected, the traffic is forwarded according to the number set in each queue. The queue ID has nothing to do with the priority. Example: If Q1~Q4 are set to 5, 3, 2, 8, the traffic at the specific port will go in the following sequence: 8 packets are stored in queue 4, 2 packets in queue 3, 3 packets in queue 2, 5 packets in queue 1, 6.2 Class of Service Configuration There are 4 types of CoS for this setting: TCP/UDP Port, TOS/DS, 802.1p and Physical Port. The user can select several options per port. Please note that if you select more than one type of CoS, the switch will arrange the packets to the assigned queue according to the following priority order: 1) TCP/UDP Port 2) ToS/DS 3) 802.1p 4) Physical Port. The following table is used to map the 802.1p field with the priority queue: Priority Field Priority Queue 6.7 Q4 4.5 Q3 0.3 Q2 1.2 Q1 For the TOS/DS priority, there are 7 types of TOS fields which can be assigned to 4 different queues: 6 b001010, 6 b010010, 6 b01110, 6 b100010, 6 b101110, 6 b and 6 b

20 6 QoS Setting 6.3 TCP/UDP Port-based COS The user can select the protocol which is forwarded in the specified mode. There are 4 user-defined UDP/TCP port groups and many known TCP/UDP ports. The port number defined by the user could be a sequence of specific numbers (depending on the screen). The theory of operation for all 4 CoS types can be represented as follows: TCP/UDP is a global setting for all ports and is not connected with the physical port. a) Priority mode: WRR. Q1=4, Q2=2, Q3=8, Q4=1 b) TCP/UDP CoS: P2 FTP Q3; P5 SMTP Q2; other protocols=q1 c) TOS/DS Setting: P5 TOS 6 b010010=q1; P2 TOS 6 b100010=q3; other TOS=Q4 d) 802.1p: P p = 6; P p = 1 e) Phys. port: P2 = Q4, P2=Q3 20

21 6 QoS Setting According to the above rule, the CoS is executed in the following sequence: SMTP Client 1 FTP client 2 TOS/DS= 6 b p priority=6 TOS/DS= 6 b p priority=1 P5 P2 Q1 Q2 Q3 Q4 P3 FTP Server SMTP Server The actual CoS will behave as described in this table. Behaviour of the switch observed on P3 8 packets coming from P2; 2 packets coming from P2; 8 packets coming from P2; 8 packets coming from P2; 4 packets coming from P2; 8 packets coming from P2; 1 packets coming from P2; 4 packets coming from P2; 1 packets coming from P2; 1 packets coming from P2; 8 packets coming from P2; 1 packets coming from P2; Comment If TCP/UDP CoS is enabled, the other CoS setting is ignored. If TCP/UDP CoS is disabled, the switch checks TOS/DS CoS. If TOS/DS CoS is disabled, the switch checks the p field. If only the physical CoS port is enabled, the switch only checks the physical CoS port. 21

22 7 Security Filter 7.1 MAC Address Binding This feature provides a way for the administrator to define the relationship between the physical port and the MAC address. Only the packet with the specified source MAC address can be forwarded. Setting the MAC address for each port, the administrator can prevent unauthorized access to the switch by other users. Each port can equal up to 3 MAC addresses. To enable the port binding function, you must enter the correct MAC address, select the correct port number, Enable port binding and then click Update. NB It is not permitted to set the multicast address to these fields. A warning message is displayed when trying this. 22

23 7 Security Filter 7.2 TCP/UDP Port Number Selecting the TCP/UDP ports, the network administrator can optionally block a few specific applications. There are 2 types of protocol filter functions. The Forward function allows the switch to forward the selected protocol and discard other protocols. The Deny function allows the switch to discard the selected protocol and forward the other protocols. The protocol is checked at the selected secure WAN port. It should be defined on the server side. The figure below illustrates how this function is applied in a real environment. Example: a) Release TCP/UDP filter function, b) select Allow rule, c) set port 5 as secure WAN port, and FTP and TELNET as filter protocol Result: Physical port Port 5 Other ports Switch behaviour TELNET and FTP are forwarded, other protocols are ignored All protocols are forwarded like the normal packet 23

24 8 Spanning Tree 8.1 STP Bridge Settings Here you can make settings for the Spanning Tree protocol to control the behaviour of the switch in a redundant network. The switches exchange Bridge Protocol Data Units (BPDU) when STP is enabled to define a unique way of packets in the network. The bridge priority determines which switch in the network is the root bridge. The switch with the lowest bridge priority is the root bridge which determines and builds up the Spanning Tree. There are five different port statuses: Blocking: discards packets; does not learn addresses; receives and processes BPDUs Listening: discards packets; does not learn addresses; receives, processes and transmits BPDUs Learning: discards packets; learns addresses; receives, processes and transmits BPDUs Forwarding: forwards packets; learns addresses; receives, processes and transmits BPDUs Disabled: discards packets; does not learn addresses; does not receive nor process BPDUs Timers define the amount of time that a port remains in a status. Only the root bridge can change the settings. Three timers affect the status change and thus the execution speed of the algorithm: The hello timer specifies the amount of time between two BPDUs. It is 2 seconds by default. Forward Delay is the time spent in the listening and learning status. This is 15 seconds each; thus 30 seconds total for both statuses. Maximum Age checks how long a switchport keeps the configuration information. The default value is 20 seconds. The STP mode differentiates between STP and RSTP (rapid STP), and STP can be disabled. 24

25 8 Spanning Tree 8.2 STP Port Settings Here you can make the STP settings for each of the ports of the switch. Every non-root bridge selects a root port. The root port is the port of the bridge closest to the root bridge. This port is selected on the basis of the lowest path costs to the root bridge. In case of a tie, the port is searched which receives the lowest bridge ID from a neighbour. If this also leads to a tie, the port with the lowest received port priority is searched. Each segment selects a destination port. This process is the same as the one described above. The destination port of a segment is the port which is connected to the switch and which has the lowest path costs to the root switch. If there is a tie, first the lowest sent BID and then the lowest received port priority is considered. The port priority and the path costs (RPC=Root Path Cost) can be adjusted for each port. 8.3 Loopback Detection On this page, you can also enable the loopback function and auto wake-up and specify the wake-up time interval. 25

26 9 Trunk Setting On this page, you can set trunk groups for a balanced load as well as for automatic backups. The switch supports 2 trunk groups each consisting of 2 4 ports. The trunkhash algorithm can be selected according to 4 different methods. Port ID: The packet is distributed based on port ID among the trunk member ports. SA: The packet is distributed based on the MAC address of the source among the trunk member ports. DA: The packet is distributed based on the MAC address of the destination among the trunk member ports. DA&SA: The packet is distributed based on the result of the XOR calculation and the result of the source MAC address and the destination MAC address among the trunk member ports. 26

27 10 DHCP Relay Agent Here you can enable the DHCP Relay Agent and make settings. By selecting Enable and then clicking Update, the respective function is enabled. The Hops Count Limit can be set by entering the desired number and clicking Update Relay Server Here you can enter the IP address of the Relay Server. After clicking Add, the server is added to the list below VLAN Map Relay Agent Here you can create a VLAN MAP list of relay agents. To do so, enter the VLAN ID and select the desired map server. After clicking Add, the agent is added to the list. 27

28 11 Backup/Recovery This function provides the user with a method to create a backup of the configuration of the switch. The user can save the configuration file as a specific file. If you want to restore the settings saved in a special path, you must enter the password and click the Upload button. Afterwards, the saved settings of the switch are restored. 28

29 12 Miscellaneous Settings Miscellaneous settings are used to configure the output queue ageing time, VLAN stride and IGMP snooping Output Queue Ageing This function is used to prevent poor utilization of the server. If a packet has been stored in a switch for a long time, it will expire. In order to prevent bandwidth being strained by these packets, the switch offers an option for the administrator to enable the queue ageing function Stride VLAN When selecting this function, the switch forwards the uni-cast packets to the destination port regardless of whether this is in the same VLAN IGMP Snooping If this function is enabled, the switch will run IGMP snooping version 1 and version 2 without the intervention of the CPU run. The IGMP report and the discarded packets are automatically processed by the switch. 29

30 13 SNMP Settings Here you can make settings for the Simple Network Management Protocol. You can create communities by entering a name and assign Read/Write or Read Only authorizations. Click Update to apply the settings made. 14 Logout This page provides the user with the possibility to log out. To do so, click Accept. Click Back to return to the previous page. 30
