Viewing VLAN forwarding database information
Use this procedure to display the MAC addresses that are learned or statically configured for a VLAN. In order to learn you have to be connected to another switch or host and receive some traffic.
Procedure
Example
View VLAN forwarding database information:
Switch:1> show vlan mac-address-entry
================================================================================
Vlan Fdb
================================================================================
VLAN MAC SMLT
ID STATUS ADDRESS INTERFACE REMOTE TUNNEL
--------------------------------------------------------------------------------
1 learned f8:15:47:e1:80:0c Port-1/2 false -
2 learned 32:20:d3:81:00:77 Port-1/9 false -
4 learned b4:a9:5a:2b:78:31 Port-2/1 false -
3 out of 3 entries in all fdb(s) displayed.
View where entries are learned. The TUNNEL column indicates where in the SPBM network an entry is learned.

Variable Definitions
Use the data in the following table to use optional parameters with the show vlan mac-address-entry command.
|
Variable |
Value |
|---|---|
|
<1-4059> |
Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. |
|
mac <0x00:0x00:0x00:0x00:0x00:0x00> |
Specifies the MAC address. |
|
port {slot/port[-slot/port][,...]} |
Specifies the port or port list. |
|
spbm-tunnel-as-mac |
Displays where entries are learned. The TUNNEL column indicates where in the SPBM network an entry is learned. |
