mstp instance <number> interface port-
channel <port-list>

Specifies the ports you want to participate in this

MST instance.

C

no mstp instance <number> interface
port-channel <port-list>

Disables the assignment of specific ports from an

MST instance.

C

mstp instance <number> interface port-
channel <port-list> path-cost <1-
65535>

Specifies the cost of transmitting a frame to a LAN

through the port(s). It is recommended you assign it

according to the speed of the bridge.

C

13

mstp instance <number> interface port-
channel <port-list> priority <1-255>

BridgeMaxAge

This field displays the maximum time (in seconds) the Switch can wait

without receiving a configuration message before attempting to reconfigure.

BridgeHelloTime

This field displays the time interval (in seconds) at which the Switch

transmits a configuration message.

BridgeForwardDelay

This field displays the time (in seconds) the Switch will wait before

changing states (that is, listening to learning to forwarding).

BridgeMaxHops

This field displays the number of hops (in seconds) in an MSTP region

before the BPDU is discarded and the port information is aged.
