Your storage system includes an SNMP agent that responds to queries and sends
traps to network management stations. Your storage system's SNMP
agent does not have write privileges—that is, it cannot be used to
take corrective action in response to a trap.
Starting with Data ONTAP 7.3.1, the SNMP agent supports IPv6 transport.
You can configure the SNMP agent on your storage system in a variety of ways:
- Verify that SNMP is enabled. SNMP is enabled by default in Data ONTAP.
- Enable traps. Although SNMP is enabled by default, traps are disabled by
default.
- Specify one or more network management station host names.
Note: No traps are sent unless at least one SNMP management station is
specified as a trap host. Trap notifications can be sent to a
maximum of eight network management stations.
You can optionally do any or all of the following:
- Provide courtesy information about storage system location and
contact personnel.
- Set SNMP access privileges.
You can restrict SNMP access on a host or interface basis.
- Specify SNMP communities.
Community strings function as group names to establish trust
between SNMP managers and clients. Data ONTAP imposes the following
limitations on SNMP communities:
- No more than eight communities are allowed.
- Only read-only communities are supported.
- Enable query authentication.
You can enable SNMP agent authentication failure traps, which
are generated when the agent receives queries with the wrong
community string. The traps are sent to all hosts specified as trap
hosts.
- Create and load user-defined traps.
Note: Storage systems in an active/active configuration can have different SNMP
configurations. For more information, see the na_snmp(1) man page.
