Configuration Guidelines

The switch supports up to 16 MST instances. The number of VLANs that can be mapped to a particular MST instance is 1024.

In a spanning tree network, the switches can be in the same MST region only when they have the same VLAN-to-instance map, configuration revision number, and name.
