Description
Use the
display stp tc
command to display the statistics of TC/TCN BPDUs received and sent by all ports
in an MSTI or all MSTIs.
If you do not specify an MSTI ID, this command will display the statistics of TC/TCN BPDUs 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 ID, this command will display the statistics of TC/TCN BPDUs received and sent
by all ports in the specified MSTI, in port name order.
Examples
# Display the statistics of TC/TCN BPDUs received and sent by all ports on the IRF member device 1 in
MSTI 0.
<Sysname> display stp instance 0 tc slot 1
