Autosupport Alert
HA Group Notification (CLUSTER NETWORK DEGRADED) ALERT

The EMS log shows that the e0d port is in the degraded state.

[vifmgr.port.monitor.failed:error]: The "link_flapping" health check for port e0d (node node-01) has failed. The port is operating in a degraded state. [vifmgr.portDeg.lifMoved:notice]: LIF node-01_clus2 (on virtual server ****), IP address *****, is being moved to node node-01, port e0c from node node-01, port e0d because the port's health status is in a degraded state.

The network port show command also found that Node1's e0d port was in a degraded state.

The two Cluster ports of the partner node are both in healthy status.
Resetting the direct attach cable does not improve the situation.
