::> system health alert show
Node: sanpc254
Alert ID: SwitchSNMPCommunication_Alert
Resource: sancl201-cs01(XXXXXXXX)
Severity: Major
Indication Time: Tue Apr 22 02:58:38 2025
Suppress: false
Acknowledge: false
Probable Cause: SNMP communication from the node to the ethernet
switch has failed repeatedly. Invalid SNMP settings
are configured with ONTAP Switch Health Monitoring or
on the Ethernet switch.
Possible Effect: Ethernet switch communication problems and
accessibility issues.
Corrective Actions: 1) Check the SNMPv2c community or SNMPv3 username on the Ethernet switch to verify
that the expected community string or username is configured.
To view the expected community string or username, run the "system switch ethernet show -snmp-config" command.
2) (SNMPv3) Verify that the SNMPv3 credentials are present within ONTAP.
To view the established SNMP logins, run the "security login show -application snmp" command.
If a custom engine-id was provided for the SNMPv3 user,
ensure it is same as that of the remote switch.

• Intermittently seeing a number of SwitchSNMPCommunication_Alert then it gets cleared eventually.
