Viewing Chassis Information 2-11
The SmartSwitch 2000 Chassis View
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
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
SmartSwitch 2000 from one network segment to another. Bridge topology
information will be forwarded by the port.
• UNK (Unknown) if the interface’s status cannot be determined.
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. For the SmartSwitch 2000 devices, the front panel bridge interfaces
will map directly to each interface’s ifIndex.
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:
• ON if the port is currently forwarding packets.
• OFF if the port is not currently forwarding packets.
Load
If you choose Load, the interface text boxes will display the percentage of
network load processed by each port during the last polling interval. This
percentage reflects the network load generated per polling interval by devices
connected to the port compared to the theoretical maximum load (10, 100, 155.5,
or 1000 Mbps) of the connected network.
