The 9A128-01 Module View

Bridge Port State

If you choose the Bridge Port State mode, a bridge port is considered:

•FWD (Forwarding) if the port is on-line and forwarding packets across the 9A128-01 from one network segment to another.

•DIS (Disabled) if 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) if 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.

•LIS (Listening) if the port is not adding information to the filtering database. It is monitoring Bridge Protocol Data Unit (BPDU) traffic while preparing to move to the forwarding state.

•BLK (Blocking) if the port is on-line, but filtering traffic from going across the 9A128-01 from one network segment to another. Bridge topology information will be forwarded by the port.

•BRK (Broken) if the physical interface has malfunctioned.

Bridge Mapping

If you have selected the Bridge Mapping status mode, the port display will alter to show the physical interface index (ifIndex) associated with each front panel bridge port.

Bridge Port Status Color Codes

The Bridge Port Status Display options will use the following color code, regardless of which bridge port status option is selected: green = forwarding, blue = disabled, magenta = learning and listening, orange = blocking, and red = broken.

The FDDI Port Status Displays

When you open the Module View, each FDDI port on the 9A128-01 will by default display its current connection status (defined below); to change this status display, select one of the options on the Port Status menu, as described in the previous section.
