DesignatedPriority Shows the following:
• Root – Shows the ID of the root bridge for this bridge.
• Bridge – Shows the ID of the Designated bridge that is
associated with this port.
ActiveTimers Shows what timers are currently active on this port and the number of
seconds they have before they expire:
• rrWhile – Recent root timer. A non-zero value means that the port
has recently been a Root port.
• rcvdInfoWhile – Received information timer. Shows the time
remaining before the information held by this port expires (ages
out). This timer is initialized with the effective age parameter.
(See “Max Age” on page 7-48.)
• rbWhile – Recent backup timer. A non-zero value means that the
port has recently been a Backup port.
• helloWhen – Hello period timer. The value shown is the amount of
time between hello messages.
• tcWhile – Topology change timer. The value shown is the interval
when topology change notices can be propagated on this port.
• fdWhile – Forward delay timer. (See the explanation for Fwd Dly
on page 49.)
• mdelayWhile – Migration delay timer. The amount of time that a
bridge on the same LAN has to synchronize its migration state
with this port before another BPDU type can cause this port to
change the BPDU that it transmits.
Machine States The current states of the various state machines on the port:
• PIM – State of the Port Information state machine.
• PRT – State of the Port Role Transition state machine.
• PST – State of the Port State Transition state machine.
• TCM – State of the Topology Change state machine.
• PPM – State of the Port Protocol Migration.
• PTX – State of the Port Transmit state machine.
Refer to the section “State Machines” on page 7-23 for details on state
machines.
Received Shows the number of BPDU types the port has received:
• RST BPDU – BPDU in 802.1W format.
• Config BPDU – Legacy configuration BPDU (802.1D format).
• TCN BPDU – Legacy topology change BPDU (802.1D format).
