Designated Port Cost: Path Cost offered to the LAN by the Designated Port.
Designated Bridge: The bridge containing the designated port.
Designated Port Identifier: Port on the Designated Bridge that offers the lowest cost to the LAN.
Topology Change Acknowledgement: Value of flag in next Configuration Bridge Protocol Data
Unit (BPDU) transmission indicating if a topology change is in progress for this port.
Hello Time: The hello time in use for this port.

This command displays the settings of one or all ports within the specified multiple spanning tree
instance. The parameter <0-4094> indicates a particular MST instance. The parameter {<slot/port> | all}
indicates the desired switch port or all ports.
If 0 (defined as the default CIST ID) is passed as the <0-4094>, then the status summary is displayed for
one or all ports within the common and internal spanning tree.
Syntax

<0-4094> - multiple spanning tree instance ID.
<slot/port> - is the desired interface number.
all - All interfaces.
Default Setting
None
Command Mode
Privileged Exec
Display Message
