Viewing Chassis Information

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:

You can view four port status categories, as follows:

¥

 Ñ FWD, DIS, LRN, LIS, BLK, BRK, UNK

¥

 Ñ the physical interface associated with a bridge port

¥

 Ñ ON or OFF

¥

Ñ 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 
SmartSwitch 2000 from one network segment to another.

¥

DIS (Disabled) if bridging at the port has been disabled by management; no 
trafÞc can be received or forwarded on this port, including conÞguration 
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 trafÞc, and learning network addresses.

¥

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

¥

BLK (Blocking) if the port is on-line, but Þltering trafÞc from going across the 
SmartSwitch 2000 from one network segment to another. Bridge topology 
information will be forwarded by the port.

¥

UNK (Unknown) if the interfaceÕs status cannot be determined.
