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
page 394.)
•
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
•
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.
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
machines.
Shows the number of BPDU types the port has received:
•
RST BPDU – BPDU in RSTP format.
•
Config BPDU – Legacy configuration BPDU (802.1D format).
