The Bridge Status Window

Bridging

•

 (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.

•

 (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.

•

 (red) — the physical interface has malfunctioned.

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.

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

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

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, 

).

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, 

•

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

•

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

). 

•

The Duplex Modes window, which allows you to configure duplex mode (on 
or off) for standard Ethernet interfaces; see Duplex Modes, 

, for 

details.
