Chapter 23: Multiple Spanning Tree Protocol
532 Section IV: Spanning Tree Protocols
Associating VLANs to MSTI IDs
When you create a new MSTI, you are given the opportunity to associate
VLANs to it. But once a MSTI is created, there might come a time when
you want to add more VLANs, or perhaps remove VLANs from it. This
procedure explains how to associate VLANs on the switch to an existing
MSTI and also how to remove VLANs. Before performing this procedure,
note the following:
ˆ You must create an MSTI before you can assign VLANs to it. To create
a MSTI ID, refer to “Creating, Deleting, and Modifying MSTIs” on
page 528.
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.
ˆ You can also associate VLANs to an MSTI by performing the
procedure “Modifying an MSTI” on page 530.
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 “Selecting MSTP as the Active Spanning Tree
Protocol” on page 522.
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 523.
To add or remove a VLAN from an MSTI, do the following:
1. From the MSTP Menu, type V to select VLAN-MSTI Association Menu.
