Bridging

¥The SmartTrunk 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 Token Ring Bridge Mode window lets you select which type of bridging that will be used by the Token Ring bridging deviceÑTransparent, Source Routing, or Source Route Transparent (see Token Ring Bridge Mode, page 4-83).

¥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 Bridge and Port ConÞguration Windows, page 4-92).

¥The Port ConÞguration option opens a window that allows you to view the address and routing information for an individual Token Ring bridging interface. This window displays information that is set at the device level via the Bridge ConÞguration window, such as the Bridge Number and the Virtual Ring Number. It also allows you to set source route bridging parameters for that port (see Using the Bridge and Port ConÞguration Windows, page 4-92).

¥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 Interface ConÞguration Window, page 4-89).

¥The Source Route ConÞguration option enables you to conÞgure source routed trafÞc passing between bridge ports (see Source Route ConÞguration, page 4-57).

NOTE

The menu options that are available will vary depending on the type of device you are monitoring, and on the type of bridge interfaces supported by the device.

The following sections detail how to use each of the bridge management windows.
