Chapter 23: Multiple Spanning Tree Protocol
452 Section V: Spanning Tree Protocols
Adding, Removing, and Modifying VLAN Associations to MSTI IDs
When you create a new MSTI ID, you are given the opportunity of
associating VLANs to it. But after an MSTI ID is created, you may 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:
ˆ
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 449.
ˆ
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.
ˆ
An MSTI can contain any number of VLANs.
This section contains the following procedures:
