  • Page 22: Ieee 802.1Q Standard

    1.2.1 IEEE 802.1Q Standard IEEE 802.1Q is a standard for virtual bridged local area networks (VLANs). It provides an alternate method for forwarding packets through a switch. In an 802.1D (Spanning Tree) bridge, packets are forwarded in accordance with the spanning tree as dynamically created by the 802.1D protocol (Bridge Protocol...

  • Page 23: 802.1Q Mode On Els10-27Tx

    1.3.1 VLAN Hybrid Ports (802.1Q Mode) A VLAN Hybrid port is used to connect one or more VLAN-aware or VLAN- unaware devices to the switch. Both tagged and untagged frames can be received and transmitted on Hybrid ports. If a port on the ELS10-27TX is not configured as an Access port, it is a Hybrid port.

  • Page 24: 802.1Q Trunk Ports

    Introduction 1.3.3 802.1Q Trunk Ports An 802.1Q trunk port passes all packets with the tag in place. It will not strip the tag. The port must be a hybrid port. There is no explicit command to create 802.1Q trunks ports. The following are two ways of implementing trunk ports: •...

    VLAN. If multiple VLANs are configured on a switch, you can configure multiple IP addresses provided they are on separate subnets. Therefore, when an IP address is assigned to a switch, the VLAN ID for the subnet must be specified. When the network management processor issues a response to a network management packet, it selects the correct VLAN ID to use based on the IP subnet.

  • Page 26: Switch Mode

    The unit will not operate in a mixed mode. The default is to operate in 802.1D mode. For further information, refer to Switch Command in Chapter 2, Enhancements to LCM Commands.

  • Page 27: Restricting Vlans (802.1Q Mode)

    1.3.8 Restricting VLANs (802.1Q Mode) This command will allow you to specify a list of VLAN IDs that should not be dynamically learned by GVRP. When the management processor receives a GVRP packet, it checks this database to determine if the learning of this ID should be restricted.

  • Page 28: Workgroups

    Workgroup. The packet will then be forwarded or filtered based on that single Workgroup marking. When a packet leaves the switch, the packet will appear just as it did when it was received on the inbound port.

  • Page 29: Default Gateway

    1.5 DEFAULT GATEWAY A default gateway field was added to the router command to allow communication to a device on a subnet not configured on this switch. For information on configuring the Default Gateway, refer to Chapter 2, Enhancements to LCM Commands.

  • Page 31: Chapter 2 Enhancements To Lcm Commands

    The Local Console Manager (LCM) is a command-line interface built into the SmartSTACK Ethernet ELS10-27TX. The LCM enables you to monitor, manage, and configure the switch through the RS232C connection attached to any non- intelligent terminal or workstation running terminal emulation.

    2.4 BASIC LCM COMMANDS To manage the SmartSTACK Ethernet ELS10-27TX using LCM, you first must connect the switch to an ASCII terminal or terminal emulator. To use LCM, begin by pressing the Enter key several times to get the LCM prompt (ELS10-27>).

  • Page 35: Lcm Commands

    The following is a list of commands that were modified for this release: • Enable Command • Route Command • Port Command • Switch Command • Trap Control Command • VLAN Command Commands are listed alphabetically in this chapter. 2.5.1 Enable Command (Address Limit) The address limit parameter was added to the enable command.

  • Page 36: Route Command

    2.5.2 Route Command A default gateway field was added to the route command to allow communication to a device on a subnet not configured on this switch. The gateway address must be for a subnet already configured on this switch. A VLAN ID is not necessary for the gateway as it will use the VLAN ID associated with the subnet address already configured.

  • Page 37: Port Command

    2.5.3 Port Command The Port command allows you to configure the port(s) on the unit in regards to speed, duplex mode, broadcast storm protection values, GVRP, access ports, control, and the default VLAN ID used on each port. If the default VLAN ID for a port was configured, the port will not automatically become a member of that VLAN.

  • Page 39: Switch Command

    The SmartSTACK Ethernet ELS10-27TX supports two forms of Virtual LANs. One is the IEEE 802.1Q standard (spanning tree) and the other is Workgroups. The switch command allows you to select the mode in which the SmartSTACK Ethernet ELS10-27TX operates. Prior to changing to 802.1Q mode, all Workgroups must NOTE be deleted.

  • Page 40: Trap Control Command

    NMS IP address that it learned. To avoid this, configure an IP address for the intended NMS. If the trap command is not used, the switch will continue to learn the IP address of the last NMS it heard from and will send traps only to that address.

  • Page 41: Vlan Command

    Refer to the port command to change the default VLAN ID for a port. If the restriction option is specified, the switch will not allow a VLAN to be established for that ID on the specified group of ports from either a user interface or GVRP.

  • Page 44: Modifying, Creating And Deleting Vlans

    Configuring VLANs Using SNMP 3.2.1 Modifying, Creating and Deleting VLANs VLAN information that is being modified, created or deleted will remain in local variables until the status variable is set. At that time, the local variables will be processed, the Global VLAN Table will be updated and the hardware configuration modified.

  • Page 45: Creating A Vlan

    • If the IP address was specified, the IP address is set. • If the switch is operating in 802.1Q mode, the following will be performed by the firmware: The hardware is informed of which ports on the VLAN to delete.

  • Page 46: The Config Egress List

    Configuring VLANs Using SNMP The selected ports are removed from the list of ports in the table entry. If there are no ports left on the VLAN, and the VLAN ID does not equal 0x001, then the BPDU addresses and the MP MAC address is deleted from the address database.

  • Page 47: Modifying A Config Egress List Entry

    The ports selected are added to the existing list of ports in the table entry. If the switch is operating in 802.1Q mode, the following will be performed by the firmware: • Inform the hardware of the new PVID for the port(s).

  • Page 48: The Filter Gvrp Table

    Configuring VLANs Using SNMP 3.4 THE FILTER GVRP TABLE The Filter GVRP Table can be used to inhibit VLANs from being learned via GVRP. It can also be used to inhibit a user from accidentally configuring a port on a VLAN they do not want. In the other tables, there are several local variables associated with the Filter GVRP Table, such as index, the VLAN ID, the list of ports, the status, and establish.

  • Page 49: Creating A Filter

    If all of these checks pass, the VLAN ID is copied into the table entry and the ports are added to the existing port mask. If the switch is operating in 802.1Q mode, the command is passed to the GVRP task, all of the learned addresses on the VLAN are deleted, and all ARP entries are flushed.

  • Page 50: The Static Mac Entry

    Configuring VLANs Using SNMP 3.5 THE STATIC MAC ENTRY Only three local variables are accessible, the VLAN ID; the MAC address, and the port to associate with this entry. MAC addresses added via this mechanism are not saved after a reboot, and will not age. For a list of Static MAC variables, refer to Chapter 3, Configuring VLANs Using SNMP.

    Configuring Workgroups Using LCM 5.2 WORKGROUP CONFIGURATION EXAMPLES Figure 5-1 shows an example of a typical Workgroup configuration. In this example, two Workgroups are used: Workgroup Alpha and the Default Workgroup. Workgroup Alpha contains ports 3,5,7 and 9, and the Default Workgroup contains all ports not contained in Workgroup Alpha.
  • Page 77 Configuring Workgroups Using LCM It is also possible to overlap workgroups. Figure 5-2 shows how overlapping ports can communicate with ports in both Workgroups. For example, Workgroup Alpha 3-7 and Workgroup Omega 7-9. In this example, four workgroups would be created, Alpha, Omega, the default, and a superset workgroup containing all ports in Alpha and Omega.

    Configuring Workgroups Using LCM one of these ports, the MAC address and Workgroup pair is found in the database and sent to port 7. In our example, the packet was received on port 3 and paired with Workgroup Alpha (0x065). Conversely when packets are received on other ports (Port 3 in this example) they also will have additional entries placed into the database.

    Configuring Workgroups Using SNMP 6.2 WORKGROUP CONFIGURATION PROCEDURES You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful. SNMP Configuration information is shown on the following pages. To configure workgroups using SNMP, proceed as follows: Step Action Read els10-27WorkGroupCurrentCount.
  • Page 83 Configuring Workgroups Using SNMP If ports are added to an existing workgroup, the index into the workgroup table would be written to els10-27WorkGroupNumber. This would be obtained by first reading all of the entries in the workgroup table. The name of the workgroup you want to add ports to would be written to els10-27WorkGroupName.

    The tag identifies which VLAN the frame belongs to. The tag may be added to the frame by the end station itself or by a network device, such as a switch. In the example in Figure A-1 below, the workstations attached to the top switch are members of the same two VLANs as the workstations attached to the bottom switch.
