Cabletron Systems 2.2 manual Bridging

Bridging

¥Enable Bridge and Disable Bridge options allow you to administratively activate or deactivate bridging at the device level; see (Enabling and Disabling Bridging, page 2-14, for details.

¥The Bridge ConÞguration option opens a window that allows you to set address and routing information for all interfaces on a Token Ring bridging device, including the Bridge Number and the Virtual Ring Number. It also allows you to set source route bridging parameters at the device level. See Using the Token Ring Bridge and Port ConÞguration Windows, page 2-65, for details.

The individual bridge port index () menu that you can access from the Bridge Status window will provide the following options, depending on which device you are monitoring through SPECTRUM Element Manager:

¥The Connection Type window displays a text description of the connection type of the selected bridge interface.

¥The Description option displays a text description of a bridge interface from the ifDescr value of the ifIndex related to the selected port.

¥The Performance Graph window graphically displays the trafÞc passing between your bridged networks, and lets you compare and contrast trafÞc processed by each interface; see Performance Graphs, page 2-15,for details.

¥The Source Addressing window displays the contents of the deviceÕs Filtering Database with respect to a selected port. This will display the source MAC addresses that have been detected by the port as it forwards data across the network. The window also lets you set the aging timer that controls how long an inactive MAC address will continue to be stored in the Source Address Database before being aged out. See Source Route ConÞguration, page 2-62, for details.

¥The PPP Link Status option invokes the PPP Link Statistics Window, which enables you to view color-coded statistics related to the PPP (Point-to-Point Protocol) link at the selected interface; see PPP Link Statistics, page 2-25, for details.

¥The Source Route Statistics option opens a window that allows you to view statistics for source routed trafÞc passing between bridging ports. The window enables you to view the frames that were received, transmitted, and discarded by the bridge. See Source Route Statistics, page 2-31,for details.

¥The I/F ConÞguration port-level menu option invokes the Interface ConÞguration window, which allows you to select a bridging method for a Token Ring bridging interface. This window also allows you to select one of three transmission methods that should be used when unknown addresses are received from end stations attached to the selected bridge port. See Using the Novell Translation Window, page 2-97, for details.

¥The Source Route ConÞguration option opens a window that enables you to conÞgure source routed trafÞc passing between bridging ports; see Source Route ConÞguration, page 2-57, for details.
