The
Bridge Port State
If you choose the Bridge Port State mode, a bridge port is considered:
•FWD (Forwarding) if the port is
•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
•BRK (Broken) if the physical interface has malfunctioned.
Bridge Mapping
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.
Bridge Port Status Color Codes
The Bridge Port Status Display options will use the following color code, regardless of which bridge port status option is selected: green = forwarding, blue = disabled, magenta = learning and listening, orange = blocking, and red = broken.
