What does the PVC status STATIC indicate?

1. The local LMI mechanism is operational

2. The local LMI mechanism on the interface is disabled

3. The PVC is configured but not active

4. The PVC is not recognized by the switch

The correct answer is: The local LMI mechanism on the interface is disabled

A PVC (Permanent Virtual Circuit) status of STATIC indicates that the local LMI (Local Management Interface) mechanism on the interface is disabled. In the context of frame relay networking, if the PVC status is marked as STATIC, it means that the interface is configured to use a static mapping of PVCs instead of dynamically learning about PVCs from the network. The STATIC configuration indicates that the switch is not actively managing the PVCs through the LMI protocol, which would typically allow for dynamic updates and changes to connections based on the network's current state. When LMI is disabled, the interface will not be able to send or receive LMI status messages, thus preventing it from updating its knowledge of the state of the PVCs and their associated resources. Understanding the implications of LMI settings is crucial for network management and troubleshooting, especially in environments utilizing frame relay technology, where PVCs are fundamental to establishing connected virtual circuits between devices.
