Refer to the exhibit. A network engineer is troubleshooting a Cisco Nexus 5000 Series Switch. The interface between the server and the switch is not operational and is expected to run at 10 Gbps. The interface drain rate is 3 Mbps. Which action resolves the issue?

Explanation

A 10-Gbps Nexus 5000 interface with a drain rate below 5 Mbps can be error-disabled after receiving excessive Xoff pause frames, producing the pauseRateLimitErrDisable condition. Enabling pause error-disable recovery allows the switch to recover an interface disabled for the pause-rate-limit cause and retry bringing it up; it is appropriate when the condition is transient.
