Managing Frame Relay Services
By default, all virtual circuits on a
WSX
port have a Bridging service and are assigned to
Group 1. The
frmodify
command allows you to change this default bridging service to another
Group and to set up a default routing service for the port. See Setting Configuration Parame-
ters on page 29-22 for information on the
ters on page 29-22 for information on the
frmodify
command.
To extend your control over a Frame Relay service, you can use Service menu commands.
These command allow you to create and modify bridging, routing, and trunking services by
assigning specific virtual circuits and Groups to the services.

Setting up a bridging service requires you to map a virtual circuit to a Group. Setting up a
routing service requires you to map one or more virtual circuits to a Group. And setting up a
Trunking service requires you to map a single virtual circuit to one or more Groups. The
diagrams below illustrate the relationship between Groups, virtual ports and virtual circuits for
each Frame Relay service type:
