Parameters
instance instance-id: Displays the status and statistics of a specific MSTI. The value of instance-id ranges
from 0 to 15, where 0 represents the common internal spanning tree (CIST).
interface interface-list: Displays the spanning tree status and statistics on the ports specified by a port list,
in the format of interface-list = { interface-type interface-number [ to interface-type
interface-number ] }&<1-10>, where &<1-10> indicates that you can specify up to 10 ports or port
ranges.
Description
Use the display stp command to display the spanning tree status and statistics.
Based on the spanning tree status and statistics, you can analyze and maintain the network topology or
check whether spanning tree is working normally.
In STP or RSTP mode, follow these guidelines:
If you do not specify any port, this command displays the spanning tree information for all ports.
The displayed information is sorted by port name.
If you specify a port list, this command displays the spanning tree information for the specified ports.
The displayed information is sorted by port name.
In MSTP mode, follow these guidelines:
If you do not specify any MSTI or port, this command displays the spanning tree information of all
MSTIs on all ports. The displayed information is sorted by MSTI ID and by port name in each MSTI.
If you specify an MSTI but not a port, this command displays the spanning tree information on all
ports in that MSTI. The displayed information is sorted by port name.
If you specify some ports but not an MSTI, this command displays the spanning tree information of
all MSTIs on the specified ports. The displayed information is sorted by MSTI ID and by port name
in each MSTI.
If you specify both an MSTI ID and a port list, this command displays the spanning tree information
on the specified ports in the specified MSTI. The displayed information is sorted by port name.
The MSTP status information includes the following parameters:
CIST global parameters:
{ Protocol work mode
{ Device priority in the CIST (Priority)
{ MAC address
{ Hello time
{ Max age
{ Forward delay
{ Maximum hops
{ Common root bridge of the CIST
{ External path cost from the device to the CIST common root
{ Regional root
{ Internal path cost from the device to the regional root
