The 9A128-01 Module View
2-10 Viewing Module Information
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.
