What command will display the line, protocol, DLCI, and LMI information of an interface?

  • A.sh pvc
  • B.
    show interface
  • C.show frame-relay pvc
  • D.show run

Answer: B

Correct answer: show interface

show interface reports the line status and line protocol status, and on a Frame Relay interface it also shows the LMI type and DLCI information. show frame-relay pvc gives fuller PVC detail - the DLCI status and the congestion counters - but not the line and protocol status of the interface itself, which is why the single interface command is the one that covers all four items asked for.
