Assigning a VLAN to a Spanning Tree Group
If no VLANs exist beyond the default VLAN 1 see “Creating a VLAN” on page 78 for
information on adding ports to VLANs.
Assign the VLAN to the STG using the following command:
If the association between the spanning-tree group and a VLAN is broken, the spanning-
tree parameters are cleared. Reconfigure all of the parameters for the STG.
Each STG must have a VLAN assigned to it before it becomes functional. You cannot
configure other STG settings until the VLAN is assigned. If the STG VLAN is unas-
signed, other configuration settings are cleared. Assign a VLAN and reconfigure the STG
settings.
NOTE – To ensure proper operation with switches that use Cisco Per VLAN Spanning
Tree (PVST+), you must either:
create a separate STG for each VLAN, or
manually add all associated VLANs into a single STG.
