Cabletron Systems CSX400 Accessing Other Options from the Bridge Status Window, Interface Type

Bridging

¥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 Mb/s or Gb/s.

Accessing Other Options from the Bridge Status Window

At the top of the Bridge Status window, you can click 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 TypeÉ window displays a description of the device that is currently being monitored.

¥The Find Source AddressÉ window allows you to discover the bridge interface through which a particular MAC address is communicating (see Using the Find Source Address Feature, page 4-63).

¥The Performance GraphÉ window displays statistics for trafÞc across the entire bridge (see Performance Graphs, page 4-15).

¥The Spanning TreeÉ window allows you to set the Spanning Tree Algorithm parameters for bridging on your device (see Bridge Spanning Tree,

page 4-35).

¥The SmartTrunkÉ option invokes the SmartTrunk ConÞguration and Status window, which enables you to group interfaces logically to achieve greater bandwidth between devices, if both devices support the SmartTrunk feature. There is no limit to the number of ports that can be included in a single Òtrunk,Ó nor is there a limit to the number of trunked ÒinstancesÓ that can be supported (see ConÞguring SmartTrunking, page 4-96).

¥The Filtering DatabaseÉ window lets you see the contents of the Static and Learned databasesÑthe two address databases which construct the IEEE 802.1 Source Address Table. The bridge uses the contents of these databases to make its packet Þltering and forwarding decisions. You can conÞgure the bridgeÕs acquired and permanent Þltering databases to Þlter or forward trafÞc across the device (see Filtering Database, page 4-42).
