Understanding "PVC STATUS=INACTIVE" | Cisco CCNA Exam

D

The output "PVC STATUS=INACTIVE" from the "show frame-relay pvc" command indicates that the Frame Relay Permanent Virtual Circuit (PVC) is not active.

There are several possible reasons for this, including:

A. No data packets have been detected for more than five minutes: This means that the PVC is correctly configured and operating normally, but there has been no data traffic flowing over the PVC for more than five minutes. In this case, the PVC will be marked as inactive until data traffic is detected again.

B. The PVC is no longer actively seeking the address of the remote router: This means that the PVC is configured correctly and was previously active, but it is no longer actively seeking the address of the remote router. This can occur if the remote router is down or if there is a problem with the configuration of the remote router.

C. The PVC is waiting for "interesting" traffic to trigger a call to the remote router: This means that the PVC is correctly configured, but it is not currently active because there is no "interesting" traffic flowing over the PVC. "Interesting" traffic is traffic that matches a configured access list or that meets certain criteria defined by the network administrator.

D. There is a problem on the remote end of the PVC: This means that the PVC is correctly configured on the local switch, but there is a problem with the configuration of the remote router or switch. This could be due to a misconfiguration of the remote router or switch or a problem with the physical connection between the two devices.

E. The PVC is not configured on the switch: This means that the PVC has not been configured on the local switch.

In summary, "PVC STATUS=INACTIVE" from the "show frame-relay pvc" command indicates that the Frame Relay Permanent Virtual Circuit (PVC) is not active for one of the reasons mentioned above. The specific reason must be determined through further troubleshooting.
