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 4-215) with the same set of instances, and the same
instance (on each bridge) with the same set of VLANs. Also, note that
