Managing SNMP on the cluster (cluster administrators only)

Enabling SNMP provides a mechanism for monitoring your cluster to avoid issues before they occur and to respond to issues when they occur. Managing SNMP involves enabling SNMP, configuring SNMP users, and configuring SNMP traphosts for specific events.

If you enable SNMP in Data ONTAP, SNMP managers can query your storage system's SNMP agent for information. The SNMP agent gathers information and forwards it to the SNMP managers. The SNMP agent also generates trap notifications whenever specific events occur. The SNMP agent on the storage system has read-only privileges—that is, it cannot be used for any set operations or for taking a corrective action in response to a trap. In Data ONTAP Cluster-Mode, SNMP is enabled cluster-wide.

For diagnostic and other network management services, Data ONTAP provides an SNMP agent compatible with SNMP versions v1, v2c, and v3. SNMPv3 offers advanced security by using passphrases and encryption.

Enabling or disabling SNMP traps

SNMP traps enable you to monitor the health and state of various components of the storage system. You can use the Trap hosts tab to enable or disable SNMP traps on your storage system. Although SNMP is enabled by default, traps are disabled by default.
