Syntax Description
map-group-name Name of the map group. This map group must be associated with a physical interface. source-addr {e164 | x121} Type of source address. source-address Address of the type specified (E.164 or X.121). dest-addr {e164 | x121} Type of destination address. destination-address Address of the type specified (E.164 or X.121).
To display statistics about Frame Relay end-to-end keepalive, use the show frame-relay end-to-end keepalive EXEC command.
