ports. The displayed information is sorted by port name and by MSTI ID on each port.
If you specify a port but not an MSTI, this command displays the BPDU statistics of all MSTIs on the
port. The displayed information is sorted by MSTI ID.
If you specify both an MSTI ID and a port, this command displays the BPDU statistics of the specified
MSTI on the port.
In STP or RSTP mode:
If you do not specify any port, this command displays the BPDU statistics of on all ports. The
displayed information is sorted by port name.
If you specify a port, this command displays the BPDU statistics on the port.
