Section IV: Spanning Tree Protocols 377
Associating VLANs to MSTI IDs
When you create a new MSTI ID, you are given the opportunity of
associating VLANs to it. But, once a MSTI ID is created, there might come
a time when you want to add more VLANs to it, or perhaps remove
VLANs. This procedure explains how to associate VLANs on the switch to
an existing MSTI ID and also how to remove VLANs. Before performing
this procedure, note the following:
❑ You must create a MSTI ID before you can assign VLANs to it. To
create a MSTI ID, refer to Creating, Deleting, and Modifying MSTI
IDs on page 374.
❑ You can assign a VLAN to only one MSTI. By default, a VLAN, when
created, is associated with the CIST instance, which has a MSTI ID
of 0.
❑ An MSTI can contain any number of VLANs.
Note
You cannot configure MSTP parameters until you have selected the
protocol as the active spanning tree protocol on the switch. For
instructions, refer to Enabling or Disabling a Spanning Tree Protocol
on page 340.
This procedure starts from the MSTP Menu. If you do not know how to
access the menu, perform steps 1 and 2 in Configuring MSTP Bridge
Settings on page 369.
To add or remove a VLAN from an MSTI ID, do the following:
1. From the MSTP Menu, type V to select VLAN-MSTI Association Menu.
