NB-30 Bridging

Bridge State on Interface

This color-coded text box indicates the state of bridging over the port interface. Note that this state (and its corresponding color code) will also be reßected on the NB-20E/25E Port display in the Chassis View window. Possible bridge states and their corresponding colors are:

FWD (Forwarding)	(Green) The port is on-line and forwarding packets
	across the NB-20E/25E from one network segment to
	another.
DIS (Disabled)	(Blue) Bridging at the port has been disabled by
	management; no trafÞc can be received or forwarded on
	this port, including conÞguration information for the
	bridged topology.
LRN (Learning)	(Magenta) The Forwarding database is being created, or
	the Spanning Tree Algorithm is being executed because
	of a network topology change. The port is monitoring
	network trafÞc, and learning network addresses.
LIS (Listening)	(Magenta) The port is not adding information to the
	Þltering database. It is monitoring Bridge Protocol Data
	Unit (BPDU) trafÞc while preparing to move to the
	forwarding state.
BLK (Blocking)	(Orange) The port is on-line, but Þltering trafÞc from
	going across the NB-20E/25E from one network segment
	to another. Bridge topology information will be
	forwarded by the port.
BRK (Broken)	(Red) The physical interface has malfunctioned.

The port Status is taken from CabletronÕs proprietary Bridge MIB, as the NB-30 is an older bridge. Potential status conditions are:

OFF	The port is off, due to a failed network interface chip
	associated with that port.
OK/SQE ON	The port is communicating with the network and the
	transceiver making the connection to the network has
	SQE enabled.
OK/SQE OFF	The port is communicating with the network and the
	transceiver making the connection to the network has
	SQE disabled.
CARRIER LOST	Communication with the network has not been
	established or has been lost
