Some (not all) possible show commands include:
show frame-relay pvc
show frame-relay map
show frame-relay lmi
show interfaces
2
Some (not all) possible debug commands include:
debug frame-relay lmi
debug frame-relay packet
debug frame-relay events
3
If LMI is not traversing the link between the router and the switch, check the LMI type
configured on the router. If the LMI type is correct (that is, it's what the telco told you to
use), a call to the telco can be in order. It's possible that your circuit is in loopback or
experiencing other issues beyond your control.
