Default level 1: Monitor level Parameters instance instance-id: Displays the status and statistics of a specific MSTI. The value of instance-id ranges from 0 to 32, 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 ] }&, where & indicates that you can specify up to 10 ports or port ranges. slot slot-number: Displays the MSTP status and statistics on the specified IRF member switch. slot-number represents the member number of the device in the IRF. If this keyword-argument combination is not specified, this command displays the MSTP status and statistics on all IRF member switches. brief: Displays brief spanning tree status and statistics. |: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide. begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression. regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters. Description Use display stp 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 properly. In STP/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. Related commands: reset stp. 89

Description
Use
display stp
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 properly.
In STP/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.
