• Enable/Disable , which administratively turns the selected bridging port on or
off; see Viewing I/F Summary Information on page 2-13 for more
information.
The FN100 Port Status Displays
When you open the Chassis View window, each port on the FN100 will display its
Admin status (defined below); to change this status display, select one of the
options on the Port Status menu, as described in the following sections.
Selecting a Port Status View
To change the status of your ports:
1. Click on Port Status on the menu bar at the top of the Chassis View window;
a menu will appear.
2. Drag down (and to the right, if necessary) to select the status information you
want to display. The port text boxes will display the appropriate status
information.
Port status view options are:
Status
You can view four status categories for your ports:
• Bridge — FWD (forwarding), DIS (disabled), LIS (listening), LRN (learning),
BLK (blocking), BRK (broken), or UNK (unknown).
• Bridge Mapping — bridge interface index numbers
• Admin — ON or OFF
• Operator — ON or OFF
If you have selected the Bridge status mode, a port is considered:
• FWD (forwarding) when the interface is on-line and forwarding packets from
one network segment to another.
• DIS (disabled) when bridging at the interface has been disabled by
management, and no traffic can be received or forwarded on this interface.
• LIS (listening) when the interface 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.
• LRN (learning) when the Forwarding database is being created, or the
Spanning Tree Algorithm is being executed because of a network topology
change.
• BLK (blocking) when the interface is on-line, but filtering traffic from going
across the FN100 from one network segment to another.
