Command Usage
• Use this command to group VLANs into spanning tree instances. MSTP
generates a unique spanning tree for each instance. This provides
multiple pathways across the network, thereby balancing the traffic load,
preventing wide-scale disruption when a bridge node in a single instance
fails, and allowing for faster convergence of a new topology for the failed
instance.
• By default all VLANs are assigned to the Internal Spanning Tree (MSTI
0) that connects all bridges and LANs within the MST region. This
switch supports up to 58 instances. You should try to group VLANs
which cover the same general area of your network. However, remember
that you must configure all bridges within the same MSTI Region (page
4-217) with the same set of instances, and the same instance (on each
bridge) with the same set of VLANs. Also, note that RSTP treats each
