Configuring the LMI type
For a Frame Relay network, the line protocol is the periodic exchange of local management interface (LMI) packets between the OnSite device and the Frame Relay provider equipment. If the OnSite device is attached to a public data network (PDN), the LMI type must match the type used on the public network.
You can set one of the following three types of LMIs on the OnSite devices:
•ansi for ANSI T1.617 Annex D,
