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.
