MSTP Configuration Guidelines

MSTP Configuration Examples

MSTP Example 1
1. Configure port and VLAN membership on the switch.
2. Configure Multiple Spanning Tree region parameters, and set the mode to MSTP.
3. Map VLANs to MSTP instances:

This section provides important information about configuring Multiple Spanning
Tree Groups:
When the switch initially has PVRST mode enabled and VLANs 1‐255 are

configured and distributed to STGs 1‐255, when you turn on MSTP, the switch
moves VLAN 1 and VLANs 33‐128 to the CIST. When MSTP is turned off, the
switch moves VLAN 1 and VLANs 33‐255 from the CIST to STG 1.
 When you enable MSTP, a default revision number of 1 and a blank region name
are automatically configured.
The following section contains examples of how to configure multiple spanning
trees.
This section provides steps to configure MSTP on the G8264.
RS G8264(config)# spanning­tree mst configuration
RS G8264(config­mst)# name <name>
RS G8264(config­mst)# revision <0 – 65535>(Define the Region revision number)
RS G8264(config­mst)# exit
RS G8264(config)# spanning­tree mode mst(Set mode to Multiple Spanning Trees)
RS G8264(config)# spanning­tree mst configuration
RS G8264(config­mst)# instance <instance ID> vlan <vlan number or range>
(Enter MST configuration mode)
(Define the Region name)
