Viewing Chassis Information 2-11
The SmartSwitch 7000 Chassis View
¥ 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.
¥ 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.
¥ BLK (Blocking) if the port is on-line, but Þltering trafÞc from going across the
SmartSwitch 7000 from one network segment to another. Bridge topology
information will be forwarded by the port.
¥ BRK (Broken) if the physical interface has malfunctioned.
If you have selected Bridge Mapping , the port status boxes will display the bridge
interface index numbers assigned to each interface (which may or may not match
the
ifIndex values displayed via the I/F Mapping option described below).
If you have selected the Admin status mode, a port is considered:
¥ ON if the port is enabled by management.
¥ OFF if it has not been enabled or if it has been disabled through management
action.
Note that the Admin state reßects the state requested by management; depending
on the circumstances, this may or may not match the current Operator status,
described below.
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.
Note that the Operator status provides the actual status of the port; depending on
the circumstances, this may or may not reßect the Admin state currently requested
by management. For example, ports which are administratively ON but not yet
connected would display an Operator status of OFF, since no packets are being
forwarded.
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 reßects the network load generated per polling interval by devices
connected to the port compared to the theoretical maximum load (10 or 100
Mbits/sec) of the connected network.
Errors
If you choose the Errors mode, the interface boxes will display the percentage of
the total number of valid packets processed by each port during the last polling
interval that were error packets. This percentage reßects the number of errors
