Description
Use display stp tc to display the statistics of TC/TCN BPDUs received and sent by all ports in an MSTI or
all MSTIs.
In STP/RSTP mode, the displayed information is sorted by port name.
In MSTP mode, follow these guidelines:
• If you do not specify any MSTI, this command displays 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, this command displays the statistics of TC/TCN BPDUs received and sent by
all ports in the specified MSTI, in port name order.
