Which configuration excerpt temporarily shuts down interfaces for five minutes upon exceeding storm control levels?

The configuration excerpt that effectively temporarily shuts down interfaces for five minutes upon exceeding storm control levels is the one that specifies a timeout duration for error-disable conditions. Setting the "disable-timeout" to 300 seconds, or five minutes, allows the switch to disable the affected interfaces when storm control thresholds are crossed. The configuration also includes storm control action that triggers this response, ensuring that the interface is administratively down for the duration specified when storms are detected.

In this configuration, the "port-error-disable" statement is crucial. It is used to manage how long a port will be disabled after an event such as storm control detection. The associated timeout value directly correlates to the period the interface remains non-operational—thus mitigating excessive traffic temporarily without the need for manual intervention.

This excerpt provides a clear method to manage network stability during conditions that could harm performance, making it an essential aspect of network management within Ethernet switching environments. The others, while they may have similar focus points, do not specifically articulate the requirement for a timeout duration to revert the state, leading to less effective handling of storm control scenarios.
