Parameters
instance instance-list: Displays the statistics of TC/TCN BPDUs received and sent by all ports in 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.
slot slot-number: Displays the statistics of TC/TCN BPDUs received and sent by all ports in the specified
MSTI on the specified card. The slot-number argument represents the slot number of the card. If this option
is not specified, this command displays the statistics of TC/TCN BPDUs received and sent by all ports in
the specified MSTI on all cards. (In standalone mode.)
chassis chassis-number slot slot-number: Displays the statistics of TC/TCN BPDUs received and sent by all
ports in the specified MSTI 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 slot
number of the card. If this option is not specified, this command displays the statistics of TC/TCN BPDUs
received and sent by all ports in the specified MSTI on all cards of all member devices in the IRF fabric.
(In IRF mode.)
Usage guidelines
In STP or RSTP mode, the displayed information is sorted by port name.
In MSTP mode:
• If you do not specify any MSTI, this command displays the statistics of TC/TCN BPDUs that are
received and sent by all ports in all MSTIs. The displayed information is sorted by instance ID and
by port name in each MSTI.
• If you specify an MSTI, this command displays the statistics of TC/TCN BPDUs that are received and
sent by all ports in the specified MSTI, in port name order.
Examples
In MSTP mode:
# In standalone mode, display the statistics of TC/TCN BPDUs received and sent by all ports on the card
on slot 1 in MSTI 0.
<Sysname> display stp instance 0 tc slot 1

# In IRF mode, display the statistics of TC/TCN BPDUs received and sent by all ports on slot 1 of IRF
member device 1 in MSTI 0.
