::> system health alert show
               Node: CLUSTER-NODE01
           Alert ID: SwitchLinkDiscoveryProtocol_Alert
           Resource: CLUSTER-SW02
           Severity: Minor
    Indication Time: Wed Mar 13 15:15:12 2024
           Suppress: false
        Acknowledge: false
     Probable Cause: The ethernet switch is using an unsupported link
                     discovery protocol.
    Possible Effect: The change of the link discovery protocol on the
                     switch is not supported. The connected device will not
                     appear in link layer discovery commands.
Corrective Actions: Revert the discovery protocol change on the switch.

               Node: CLUSTER-NODE01
           Alert ID: UnsupportedSwitch_Alert
           Resource: CLUSTER-SW02
           Severity: Major
    Indication Time: Wed Mar 13 15:15:12 2024
           Suppress: false
        Acknowledge: false
     Probable Cause: Unsupported Ethernet switch is detected.
    Possible Effect: Communication problems and network connectivity issues
 Corrective Actions: Unsupported Ethernet switch "CLUSTER-SW02
                     (10:XX:XX:XX:XX:d8)" found. Connect a supported
                     Ethernet switch to the network.
