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 instance-id
argument is in the range of 0 to 4094, and the value 0 represents the CIST.

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 keyword-argument combination is
not specified, this command displays the spanning tree status and statistics on all cards. (In
standalone mode.)
chassis chassis-number slot slot-number: Displays the spanning tree status and statistics on the
specified card of the specified IRF member device. The chassis-number argument represents the ID
of the IRF member device. The slot-number argument represents the number of the slot that
houses the card. If this keyword-argument combination is not specified, this command displays the
spanning tree status and statistics on all cards of all member devices in the IRF fabric. (In IRF mode.)
