This section describes the function and displays the syntax of each Frame Relay command. For more information about defaults and usage guidelines, see the corresponding chapter of the Router Products Command Reference publication.
To clear dynamically created Frame Relay maps, which are created by the use of inverse ARP, use the clear frame-relay-inarp EXEC command.

frame-relay lmi-type {cisco | ansi | q933a}

frame-relay map protocol protocol-address dlci [broadcast]
