What is the purpose of the show frame-relay PVC command?

The show frame-relay PVC command is specifically designed to display statistics and information regarding permanent virtual circuits (PVCs) on Frame Relay interfaces. This command provides valuable insights such as status, DLCI (Data Link Connection Identifier), and the current state of each PVC. By using this command, network technicians can effectively monitor the performance and operational status of the PVCs, which is essential for troubleshooting connectivity issues or ensuring that the Frame Relay network is functioning optimally.

Understanding the statistics displayed by this command can help identify issues such as excessive error rates or dropped packets, enabling quick diagnosis and resolution of problems within the Frame Relay network. Therefore, it plays a critical role in maintaining and managing networks that rely on Frame Relay technology.
