ame Relay encapsulation. There are two types of Frame Relay encapsulation: cisco and ietf. The default type is cisco, which is configured with the encapsulation frame-relay command: interface Serialo/o encapsulation frame-relay You configure the ietf type with the encapsulation frame-relay ietf command. ietf Frame Relay encapsulation is usually used only when you're connecting Cisco routers to non-Cisco devices. Once you've configured Frame Relay encapsulation and the interface is up, you should begin seeing LMI status messages. If the PVC has been provisioned, you can see it with the show frame-relay PVC command: Router-A#sho frame pvc PVC Statistics for interface Serialo/o (Frame Relay DTE) Active Inactive Deleted Static Local Switched Unused DLCI = 102, DLCI USAGE = UNUSED, PVC STATUS = INACTIVE, INTERFACE = Serialo/o input pkts 0 output pkts 0 in bytes 0 out bytes 0 dropped pkts 0 in pkts dropped o Chapter 23: Frame Relay out pkts dropped 0 out bytes dropped 0 in FECN pkts 0 in BECN pkts 0 out FECN pkts 0 out BECN pkts 0 in DE pkts 0 out DE pkts 0 out bcast pkts 0 out bcast bytes 0 switched pkts 0 Detailed packet drop counters: no out intf 0 out intf down 0 no out PVC 0 in PVC down 0 out PVC down 0 pkt too big 0 shaping Q full 0 pkt above DE 0 policing drop 0 pvc create time 00:19:12, last time pvc status changed 00:19:12 Notice that the information being sent relates status information about the local DLCI, not the remote side. LMI always reports on information critical to the local rather than the remote side of the link. The same output on Router B should show a similar report detailing the link from Router B's point of view: Router-B#sho frame pvc PVC Statistics for interface Serialo/o (Frame Relay DTE) Active Inactive Deleted Static Local Switched Unused DLCI = 201, DLCI USAGE = UNUSED, PVC STATUS = ACTIVE, INTERFACE = Serialo/o input pkts 0 output pkts 0 in bytes 0 out bytes 0 dropped pkts 0 in pkts dropped 0 out pkts dropped 0 out bytes dropped 0 in FECN pkts 0 in BECN pkts 0 out FECN pkts 0 out BECN p
