Here's a copy of the config after I just typed "lock rate 56000" at the config-if mode for serial 0. Current configuration: ! version 11.1 service udp-small-servers service tcp-small-servers ! hostname R4000 ! enable secret 5 $1$1ETI$xqeVrzT8qlamhBz1pI4ZA/ ! frame-relay switching ! interface Serial0 no ip address encapsulation frame-relay frame-relay intf-type dce frame-relay route 301 interface Serial1 101 ! interface Serial1 no ip address encapsulation frame-relay clockrate 56000 frame-relay intf-type dce frame-relay route 101 interface Serial3 301 ! interface Serial2 no ip address shutdown ! interface Serial3 no ip address encapsulation frame-relay frame-relay intf-type dce ! no ip classless ! ! line con 0 password cisco login line aux 0 modem InOut line vty 0 4 password cisco login ! end Without applying clock the router won't allow the dlci's to map. This is my first attempt with a 4000 router.
