Selecting a Port Status View
To change the status view 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 three port status categories, as follows:
• Bridge — FWD, DIS, LRN, LIS, BLK, BRK, or UNK
• Admin — ON or OFF
• Operator — ON or OFF
If you have selected the Bridge status mode, a port is considered:
• FWD (Forwarding) if the port is on-line and forwarding packets across the
ATX Switch 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
ATX Switch from one network segment to another. Bridge topology
information will be forwarded by the port.
• BRK (Broken) if the physical interface has malfunctioned.
• UNK (Unknown) if the interface’s status cannot be determined.
If you have selected the Admin status mode, a port is considered:
• ON if the port is enabled by management and has a valid link.
• OFF if it has not been enabled or if it has been disabled through management
action.
If you have selected the Operator status mode, a port is considered:
