Parameters
instance instance-id: Displays the spanning tree information of a particular spanning
tree instance. The effective range of instance-id is 0 to 31, with 0 representing the
common internal spanning tree (CIST).
interface interface-list: Displays the spanning tree information on one or multiple ports.
You can provide up to 10 port lists, by each of which you can specify an individual port
in the form of interface-type interface-number, or a port range in the form of
interface-type start-interface-number to interface-type end-interface-number, where
the end port number must be greater than the start port number.
slot slot-number: Displays the spanning tree information of the card on the specified
slot.
brief: Displays brief information.
Description
Use the display stp command to view the MSTP status information and statistics
information.
Based on the MSTP status information and statistics information, you can analyze and
maintain the network topology or check whether MSTP is working normally.
Note that:
If you do not specify any spanning tree instance ID or port list, this command will
display the MSTP information on all ports. The displayed information is sequenced
by spanning tree instance ID and by port name in each spanning tree instance.
If you specify a spanning tree instance ID, this command will display the MSTP
information on all ports in that spanning tree instance. The displayed information is
sequenced by port name.
