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
show spanning-tree mst port summary <0-4094> {<slot/port> | all}
<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
MST Instance ID: The MST instance associated with this port.
Interface: The interface being displayed.
STP Mode: Indicate STP mode.
