## Configure VLANs on the Nonroot Bridge

The same configuration guidelines apply for VLANs on nonroot bridges (switch 1) as they do on the root bridge (switch 2).

1. Create a VLAN on switch 2.

       SEFOS# configure terminal
       SEFOS(config)# vlan 2
       SEFOS(config-vlan)# ports extreme-ethernet 0/3
       SEFOS(config-vlan)# exit
       SEFOS(config)# exit

2. Review the VLAN configuration.

       SEFOS# show vlan
       Vlan database
       -------------
       Vlan ID             : 1
       Member Ports        : Ex0/1, Ex0/2, Ex0/3, Ex0/4, Ex0/5, Ex0/6
       Ex0/7, Ex0/8, ...
       Untagged Ports      : Ex0/1, Ex0/2, Ex0/3, Ex0/4, Ex0/5, Ex0/6
       Ex0/7, Ex0/8, ...
       Forbidden Ports     : None
       Name                :
       Status              : Permanent
       ----------------------------------------------------
       Vlan ID             : 2
       Member Ports        : Ex0/3, Ex0/4
       Untagged Ports      : None
       Forbidden Ports     : None
       Name                :
       Status              : Permanent
       ----------------------------------------------------

3. On switch 1, verify that switch 1 learned about VLAN 2 using GVRP.

       SEFOS# show vlan
       Vlan database
       -------------
       Vlan ID             : 1
       Member Ports        : Ex0/1, Ex0/2, Ex0/3, Ex0/4, Ex0/5, Ex0/6
       Ex0/7, Ex0/8, ...
       Untagged Ports      : Ex0/1, Ex0/2, Ex0/3, Ex0/4, Ex0/5, Ex0/6
       Ex0/7, Ex0/8, ...
       Forbidden Ports     : None
       Name                :
       Status              : Permanent
       ----------------------------------------------------
       Vlan ID             : 2
       Member Ports        : Ex0/3
       Untagged Ports      : None
       Forbidden Ports     : None
       Name                :
       Status              : Dynamic Gvrp
       ----------------------------------------

   The switch propagates the VLAN declaration or registration on all of the forwarding ports in the switch. In the proceding example, when VLAN 2 was created on the nonroot bridge (switch 1), the switch propagated this information only on port Ex0/3 because port Ex0/4 is in the discarding state. Switch 2 learned about VLAN 2 through a single port (Ex0/3) using GVRP. Port Ex0/3 was added automatically to vlan2 on switch 1 because switch 2 propagated VLAN registration through port Ex0/3.
