display stp
Use display stp to display the spanning tree status and statistics information. Based on the information,
you can analyze and maintain the network topology or determine whether the spanning tree is working
correctly.
Syntax
On an MSR2000/MSR3000:
display stp [ instance instance-list ] [ interface interface-list ] [ brief ]
On an MSR4000:
display stp [ instance instance-list ] [ interface interface-list | slot slot-number ] [ brief ]

Parameters
instance instance-list: Displays the status and statistics information of the MSTIs that are specified by an
instance list, in the format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10>
indicates that you can specify up to 10 instances or instance ranges. The value range for the instance-id
argument is 0 to 4094, and the value 0 represents the CIST.
interface interface-list: Displays the spanning tree status and statistics on the ports that are 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.
brief: Displays brief spanning tree status and statistics. If this keyword is not specified, the command
displays the detailed spanning tree status and statistics.
slot slot-number: Displays the spanning tree status and statistics on the specified card. slot-number
represents the number of the slot that houses the card. If this option is not specified, this command
displays the spanning tree status and statistics on all cards. (MSR4000.)
Usage guidelines
In STP or RSTP mode:
• 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:
• 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.
