Viewing Device Information 2-13
The MultiSwitch 700 Device View
Port status view options are:
Status
You can view four port status categories, as follows:
• Bridge — FWD, DIS, LRN, LIS, BLK, or BRK
• Bridge Mapping — the instance of the physical interface associated with a
bridge port
• 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 ready to forward packets across
the MultiSwitch 700 from one network segment to another. Note that this is
also the default display for ports which are administratively enabled but not
connected.
• 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.
• 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.
• 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.
• BLK (Blocking) if the port is on-line, but filtering traffic from going across the
MultiSwitch 700 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 the Bridge Mapping status mode, the port display will alter
to show the dot1dBasePortIfIndex, which is the value of the instance of the interface
index (the MIB II ifIndex) that corresponds to each bridge/switch port on the
device. For a MultiSwitch 700 module, the dot1dBasePortIfIndex of the bridge
interfaces will map directly to the ifIndex.
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.
The Admin state reflects the state requested by management; depending on the
circumstances, this may or may not match the current Operator status, described
below.
