Display C-VLAN I-SID Information

Use the following procedure to display C-VLAN I-SID information.

Procedure

  1. Display the C-VLAN to I-SID associations:

    show vlan i-sid <1-4059>

  2. Display the IS-IS SPBM multicast-FIB calculation results by I-SID:

    show isis spbm i-sid {all|config|discover} [vlan <1-4059>] [id <1–16777215>] [nick-name <x.xx.xx>]

  3. Discover where entries are learned:

    show vlan mac-address-entry [spbm-tunnel-as-mac]

  4. Display the VLAN remote MAC table for a C-VLAN:

    show vlan remote-mac-table <1-4059>

Example

Switch:1>show vlan i-sid

Variable definitions

The following table defines parameters for the show vlan commands.

Variable

Value

i-sid <1-4059>

Displays I-SID information for the specified C-VLAN.

mac-address-entry [spbm-tunnel-as-mac]

Displays the bridging forwarding database.

Use the optional parameter, spbm-tunnel-as-mac to display the BMAC in the TUNNEL column. If you do not use this optional parameter, the TUNNEL column displays the host name. If an entry is not learned in the SPBM network, the TUNNEL column will be empty (–).

remote-mac-table <1-4059>

Displays C-VLAN remote-mac-table information.

The following table defines parameters for the show isis commands.

Variable

Value

spbm i-sid {all|config|discover}

  • all: displays all I-SID entries

  • config: displays configured I-SID entries

  • discover: displayes discovered I-SID entries

vlan <1-4059>

Displays I-SID information for the specified SPBM VLAN.

id <1–16777215>

Displays I-SID information for the specified I-SID.

nick-name <x.xx.xx>

Displays I-SID information for the specified nickname.
