NOTE
Once a bridge is created between two VLANs, the VLAN configuration mode for those VLANs is
disabled. You must remove a VLAN bridge if you want to make any changes to a VLAN contained
within the VLAN bridge.
Example
The following example configures two VLANs with each containing the same ports and a VLAN
bridge configured between them.
ServerIron(config)# vlan 222 by port
ServerIron(config-vlan-222)# tagged ethernet 1 ethernet 4
ServerIron(config-vlan-222)# exit
ServerIron(config)# vlan 333 by port
ServerIron(config-vlan-333)# tagged ethernet 1 ethernet 4
ServerIron(config-vlan-333)# exit
ServerIron(config)# vlan-bridge 222 333
Displaying VLAN bridge information
You can display information about VLAN bridging using the show vlan and show vlan-bridge
commands.
Using the show vlan command, a VLAN bridge is displayed as shown in the following.
Syntax: show vlan [<vlan-id> | ethernet <port.> ]
Using the <vlan-id> variable limits the display to the single VLAN whose ID is specified.
Using the ethernet <port> option limits the display to VLANs configured on the specified port.
