Issue

We get the below alert from ONTAP:
 
Node::> system health alert show
Node: NODEA
Alert ID: SwitchIfDead_Alert
Resource: Ethernet1/11
Severity: Major
Indication Time: Tue Oct 29 17:19:34 2024
Suppress: false
Acknowledge: false
Probable Cause: The interface
switch2(123456987)/Ethernet1/11 is up,
but it is not passing unicast traffic.
Possible Effect: The lack of transmit or receive traffic reported by
the switch can indicate issues with port-level or
switch-level data packet forwarding.
Corrective Actions: 1) Check interface counters and neighbor discovery information to verify the port's activity.
2) Check cluster and switch health status.
