Configuring Multiple Spanning Tree Protocol

This example shows how to enable IEEE 802.1s MSTP (Multiple Spanning Tree Protocol) on the switch and all of the ports and to set the bridge priority.

To make multiple switches be part of the same MSFP region, make sure the Force Protocol Version setting for all switches is IEEE 802.1s. Also, make sure the configuration name, digest key, and revision level are the same for all switches in the region.

Note

The digest key is generated based on the association of VLANs to different instances. To ensure the digest key is same, the mapping of VLAN to instance must be the same on each switch in the region. For example, if VLAN 10 is associated with instance 10 on one switch, you must associate VLAN 10 and instance 10 on the other switches.
