Viewing Device Information 2-15
The Device View
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
SmartSwitch 6000 or Matrix E7 from one network segment to another. This is also the
default display for ports which are administratively enabled but not connected. In
pre-5.1.x firmware, the default state of a port not in use is “forwarding,” whereas in the
5.1.x firmware, the default is “blocking” (BLK).
• 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
SmartSwitch 6000 or Matrix E7 from one network segment to another. Bridge
topology information will be forwarded by the port. In the 5.1.x fi rmware, the default
state of a port not in use is “blocking,” whereas in previous firmware versions, the
default is “forwarding” (FWD).
• 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
SmartSwitch 6000 or Matrix E7 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 requeste d by management; depending on the
circumstances, this may or may not match the current Operator status, described below.
