Question: 1 / 655

What action does a switch take when a port enters the errdisabled state?

Reboots the switch

Enables all ports

Shuts down the offending port

When a switch port enters the errdisabled state, it is a protective mechanism that indicates there is a problem detected on that port, such as a violation of network policies or protocol issues. In this state, the switch disables the affected port to prevent any further network disruptions or problems that could affect overall network performance.

By shutting down the offending port, the switch is able to isolate the issue, allowing administrators to investigate and address the problem without impacting the rest of the network. Once the issue is resolved, network administrators can manually re-enable the port, restoring functionality.

This action is an essential part of maintaining network stability, as it helps prevent misconfigurations or security violations from affecting other parts of the network.
