The Bridge Status Window 3-5

9E312/9E423 Module Bridging

• Learning (Magenta) — 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.

• Listening (Magenta) — 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.

• Blocking (Orange) — The port is on-line, but ﬁltering trafﬁc from going across

the 9E312/9E423 from one network segment to another. 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 9E312/9E423 Module interface

that supports bridging (i.e., Other for the INB interface, or Ethernet for the

remaining interfaces). The interface type (ifType) is a mandatory object type from

the SNMP MIB-II Interface (IF) Group.

Interface Address

Indicates the physical address of each switch interface that supports bridging.

Interface Speed

Indicates the data transmission speed supported by the interface (e.g., 10000 kbps

for Ethernet).

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:

•Spanning Tree... which brings up a window allowing you to set the Spanning

Tree Algorithm parameters for bridging on your 9E312/9E423 Module (see

Bridge Spanning Tree, following).

•Disable/Enable Bridge, which allows you to halt or start bridging across the

device (see Enabling and Disabling Bridging, following).

•Performance Graph... that brings up a window displaying statistics for trafﬁc

bridged across the module (see Bridge Statistics, following).

You can also access a Performance Graph window and Statistics window for

each individual interface by clicking on a port index button to display the

port level management options (see Bridge Statistics, following).
