Modifying a VLAN Association
To modify a VLAN association, do the following:
1. Display the Spanning Tree Expanded Page for MSTP by performing
Steps 1 through 4 in the procedure Configuring MSTP Parameters on
page 681.
2. In the CIST/MSTI Table section of the tab, the VLAN Associations field,
modify the VIDs of the VLANS that you no longer want to be
associated with this MSTI. You can specify more than one VID at a time
(e.g., 2,4,7).
3. Click Apply.
To save your changes, return to the General Tab and click Save
Changes. The changes you made are saved on the switch. Or,
proceed to the next procedure to configure the CIST priority.
