L2 Features > STP > MST Configuration Identification
Multiple Spanning Tree (MSTP) provides various load balancing scenarios by allowing multiple VLANs to be
mapped to a single spanning tree instance, providing multiple pathways across the network. For example,
while port A is blocked in one STP instance, the same port can be placed in the Forwarding state in another
STP instance.
The MST Configuration Identification page is for defining global MSTP settings, including region names,
MSTP revision level.
Figure 4.78 – L2 Features > STP > MST Configuration Identification

Revision Level(0 - 65535): This value, together with the configuration name and identical VLANs mapped
for STP instance IDs identifies the MST region configured on the switch.
