Blade ICE G8000 manual Assigning a Vlan to a Spanning Tree Group

RackSwitch G8000 Application Guide

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:

RS G8000 (config-if)#spanning-tree stp 1 vlan <1-4094>

„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.
