SRHopLimit	(Not available at this release)
(3500 and 9000 L3)
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 — Similar to listening, but 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.
stp	Configurable status of STP on a port. Provided that
	bride-wide STP is enabled, the port STP configuration
	states function as follows:
	■ enabled — STP sets the operating state of the port
	(blocking, listening, etc.) according to network
	topology characteristics. This is the default
	configuration for all ports.
	■ disabled — STP is disabled and the port is disabled.
	The port does not participate in STP decisions, frame
	reception, or frame transmission.
	■ removed — STP is disabled on the port but the port
	can still receive or transmit frames if its link state is up.
	If bridge-wide STP is disabled, this port STP setting is
	meaningless; as long as its link state is up, the port
	forwards all frames. To configure STP on a port, see
	“bridge port stpState” in this chapter.
txAllFilters	Number of frames that the bridge port discarded because
(3500 and 9000 L3)	of a user-defined packet filter on its “transmit all” path.
txBlockedDiscs	Number of frames that this bridge port discarded because
(3500 and 9000 L3)	the transmitting bridge port was not in the forwarding
	state.
