aggregate on the switch.

on that module.

Usage Guidelines
•
Three MST region attributes (configuration name, revision level, and configuration digest) define an
MST region as required by the IEEE 802.1Q 2005 standard. Switches that share the same values for
these attributes are all considered part of the same region. Currently each switch can belong to one
MST region at a time.
•
This command is available when the switch is operating in either the per-VLAN or flat Spanning Tree
mode.
•
Specify the port number or link aggregate ID along with the port or linkagg keyword to get
information related to the specified port or link aggregate.
