Configuring an SPBM Layer 2 Switched UNI on a Port

Shortest Path Bridging MAC (SPBM) supports Layer 2 Virtual Service Network (VSN) functionality where Switched UNIs are bridged over the SPBM core infrastructure.

Note

Note

EAP and FA can co-exist on the same port. EAP and FA can be enabled in any order; however, EAP must have Flex UNI enabled in order to function on an FA-enabled port. If EAP is currently enabled, FA can only be enabled if the port is a Flex UNI-enabled port.

VSP 4450 Series, VSP 8600 Series, or XA1400 Series do not support EAP and FA on the same port.

Before you begin

  • You must configure the required SPBM and IS-IS infrastructure.

About this task

To configure a Switched UNI on a port, you must create a Switched UNI I-SID, and map the port to the Switched UNI I-SID.

Note

Note

When you configure Switched UNI, Spanning tree is disabled on all the Switched UNI ports.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Enable Switched UNI on a port:

    flex-uni enable

    Note

    Note

    You cannot enable enable EAP on a Switched UNI (S-UNI) on the VSP 4450 Series, VSP 8600 Series, or XA1400 Series.

  3. Configure a Switched UNI Service Instance Identifier (I-SID):

    i-sid <1–16777215> [elan]

    This command automatically takes you to the Elan I-SID Configuration mode.

  4. Add ports to a Switched UNI I-SID:

    c-vid <c-vid> port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

  5. Add untagged traffic to a Switched UNI I-SID:

    untagged—traffic port {slot/port[/sub-port][-slot/port[/sub-port]][,...]} [bpdu enable]

  6. Display the Switched UNI information:

    show interface gigabitethernet i-sid {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Examples

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface gigabitethernet 1/1,1/2
Switch:1(config-if)#flex-uni enable
Switch:1(config-if)#i-sid 100
Switch:1(elan:100)#c-vid 10 port 1/1,1/2
Switch:1(elan:100)#untagged—traffic port 1/1,1/2 bpdu enable
