3Com 3500 manual PortNumber Logical index number that the system assigns to, Remain consecutive

bridge port summary 281

Field	Description
portNumber	Logical index number that the system assigns to the
	bridge port, which may not correspond with the physical
	port number depending on your system configuration.
	(For example, when you define a trunk, only the anchor
	port receives a portNumber.) As you add and remove
	logical ports, portNumbers are reassigned so that they
	remain consecutive.
rxDiscards	Total number of frames received on the bridge port that
	have been discarded. This value reflects a summary of all
	statistics that end with Discs, Discards, or Filters.
rxFrames	Total number of frames that this bridge port received
	from its segment. However, unlike the rxFrames field in
	the Ethernet display which counts all frames, this field
	does not count frames in error. Thus, this value may be
	lower than the value shown in the rxFrames field in the
	Ethernet display.
state	Current operating state of the port:
	■ Blocking — The bridge continues to run STP on the
	port, but the bridge does not receive packets from the
	port, learn locations of station addresses from it, or
	forward packets onto it.
	■ Listening — The bridge continues to run STP and
	to transmit configuration messages on the port, but it
	discards packets that are received on the port and does
	not transmit packets that are forwarded to the port.
	■ Learning — STP operating state in which the bridge
	receives packets on the port to learn the location of
	some of the stations that are located on the port.
	■ Forwarding — The bridge receives packets on the
	port and forwards or does not forward them,
	depending on address comparisons with the bridge’s
	source address list. Provided that the link state is up,
	this state field indicates forwarding even if STP is
	disabled for the bridge.
	■ Disabled — Management has disabled the port or
	the link state is down.
