Defining Multiple Spanning Tree 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 contains information for defining global MSTP settings, including region
names, MSTP revision level. To define MSTP:
1. Click L2 Features > Spanning Tree > MST Configuration Identification. The
MST Configuration Identification
Page
opens:
Figure 3–16. MST Configuration Identification Page
The
MST Configuration Identification Page contains the following fields:

tree instance). If a configuration name is not set, this field shows the MAC address of the
device running MSTP.
Revision Level (0-65535)
This value, together with the configuration name, and identical vlans mapped for STP
