(Extreme 220) (Routing) #
show spanning-tree mst port summary
This command displays the settings of one or all ports within the specified multiple spanning tree
instance. The parameter mstid indicates a particular MST instance. The parameter {unit/slot/port|all}
indicates the desired switch port or all ports. Instead of unit/slot/port, lag lag-intf-num can be used as
an alternate way to specify the LAG interface. lag lag-intf-num can also be used to specify the LAG
interface where lag-intf-num is the LAG port number.
If you specify 0 (defined as the default CIST ID) as the mstid, the status summary displays for one or all
ports within the common and internal spanning tree.
