Cluster::> system health alert show
Node: Cluster-01
Alert ID: SwitchSNMPCommunication_Alert
Resource: cluster-switch01
Severity: Major
Indication Time: Fri Aug 16 13:41:11 2024
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.
- The alert is triggered even after deleting it using the system health alert delete command.
- The cluster switches are being monitored successfully.
