Bridging

Learning (magenta) — the Forwarding database is being created or the Spanning Tree Algorithm is being executed due to a network topology change; the port is monitoring network traffic, learning network addresses.

Blocking (orange) — Spanning Tree Algorithm has configured this port to block (filter) frames to prevent redundant data loops in the bridged network; the port can’t receive or forward traffic. Bridge topology information will be forwarded by the port.

Broken (red) — the physical interface has malfunctioned.

Interface Type

Indicates the interface type which applies to each bridge port interface. The interface type (ifType) is a mandatory object type from the SNMP MIB-II Interface (IF) Group.

Bridge Address

Indicates the physical (MAC) address of the bridge port.

Interface Speed

Indicates the theoretical maximum speed of the selected interface: 10 Mbits for standard Ethernet; 100 Mbits for Fast Ethernet; 2500 Mbits for the INB.

Accessing Other Management Options from the

Bridge Status Window

At the top of the Bridge Status window, you can click on to access a menu that provides other bridge management options:

A Bridge Performance Graph that displays statistics for traffic across the entire bridge (see Bridge Statistics, page 5-7).

A Performance Graph window is also available for each individual interface, by clicking on a port index button to display the port level management options (see Bridge Statistics, page 5-7).

The Spanning Tree window, which allows you to set the Spanning Tree Algorithm parameters for bridging on your 9H42x-xx module (see Bridge Spanning Tree, page 5-11).

The Filtering Database window, which lets you configure the bridge’s acquired and permanent filtering databases to filter or forward traffic across the bridge port interfaces present on the selected 9H42x-xx module (see Filtering Database, page 5-19).

The Duplex Modes window, which allows you to configure duplex mode (on or off) for standard Ethernet interfaces; see Duplex Modes, page 5-25, for details.
