348 Asanté IntraCore 36000 Series
Multiple Spanning Tree Protocol
• To allow multiple spanning trees to operate over the network, you must configure a related set of
bridges with the same MSTP configuration, allowing them to participate in a specific set of spanning
tree instances.
• A spanning tree instance can exist only on bridges that have compatible VLAN instance assignments.
• Be careful when switching between spanning tree modes. Changing modes stops all spanning-tree
instances for the previous mode and restarts the system in the new mode, temporarily disrupting user
traffic.
Example
This example configures the switch to use Rapid Spanning Tree:
Console(config)#spanning-tree mode rstp
Console(config)#
16.221 spanning-tree mst configuration
Use this command to change to Multiple Spanning Tree (MST) configuration mode.
Default
No VLANs are mapped to any MST instance.
The region name is set the switch’s MAC address.
Command Mode
Global Configuration
