Bridging

Bridge State on Interface

Indicates the state of bridging over the port interface. Possible bridge states and their corresponding colors are:

¥Forwarding (green)ÑThe port is on-line and forwarding packets across the bridge from one network segment to another.

¥Disabled (blue)ÑBridging at the port has been disabled by management; no trafÞc can be received or forwarded on this port, including conÞguration information for the bridged topology.

¥Listening (magenta)ÑThe 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.

¥Learning (magenta)ÑThe 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.

¥Blocking (orange)ÑThe port is on-line, but Þltering trafÞc from going across the bridge from one network segment to another. Bridge topology information will be forwarded by the port.

Interface Type

Indicates the interface type which applies to each device bridging port interface (e.g., ethernet). The interface type (ifType) is a mandatory object type from the SNMP MIB II Interface (if) Group.

Bridge Address

Indicates the physical address of the bridge interface.

Speed

Indicates the speed of the interface in Mbps or Gbps.

Accessing Bridge Status Window Options

At the top of the Bridge Status window, you can click Bridge to access a menu that provides other bridge management options. Depending on which device you are monitoring via SPECTRUM Element Manager, the following bridge management options will be available:

¥The Module Type window displays a description of the device that is currently being monitored.

¥The Find Source Address window allows you to discover the bridge interface through which a particular MAC address is communicating; see Using the Find Source Address Feature, page 2-62, for details.

¥The Performance Graph window displays statistics for trafÞc across the entire bridge; see Performance Graphs, page 2-15, for details.
