The 9E312/9E423 Module View

The Bridge Port Menu

The menu for the INB and Ethernet bridging interfaces offers three selections:

•Performance Graph..., which brings up a statistics window speciﬁc to the

selected interface.

•Source Addressing...., which brings up a window allowing you to see which

source addresses are communicating through a switch port when it is using

802.1d bridging. See Using Port Source Addressing in Chapter 3 for more

information.

•Enable and Disable, which let you enable or disable bridging across the

selected interface; see Enabling and Disabling Bridge Ports, later in this

chapter.

The 9E312/9E423 Module Port Status Display

The port display on the 9E312/9E423 Module reﬂects device activity from a

bridging perspective. The port text boxes beneath the Bridge label indicate the

state of bridging on each switching interface supported by the 9E312/9E423.

For the 9E312, the port text box indexed “1” indicates the ﬁxed interface to the

INB-1 bus; interfaces indexed “2” through “13” indicate the front panel 10BASE-T

Ethernet switching interfaces.

For the 9E423-24, the port text box indexed “1” indicates the ﬁxed interface to the

INB-2 bus; interfaces indexed “2” through “25” indicate the user-interfaces

available through the two RJ71 Telco front panel connectors.

For the 9E423-36, the port text box indexed “1” indicates the ﬁxed interface to the

INB-2 bus; interfaces indexed “2” through “37” indicate the user-interfaces

available through the three RJ71 Telco front panel connectors.

The bridge state at each port can be one of the following:

FWD (Forwarding) (Green) The port is on-line and forwarding packets

across the 9E312/9E423 from one network segment to

another.

DIS (Disabled) (Blue) Bridging at the port has been disabled by

management; no trafﬁc can be received or forwarded on

this port, including conﬁguration 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 trafﬁc, and learning network addresses.
