How to monitor your storage system with SNMP
If you enable SNMP in Data ONTAP, the SNMP managers can query your storage system's SNMP agent for information. The SNMP agent gathers information and forwards it to the managers by using SNMP. The SNMP agent also generates trap notifications whenever specific events occur.
For diagnostic and other network management services, Data ONTAP
provides an SNMP agent compatible with SNMP versions 1 and 3. SNMPv3 offers advanced security by using pass phrases and encryption. SNMPv3 supports the MIB-II specification and the MIBs of your storage system. The following MIB-II groups are supported:
- Address translation
Transmission and EGP MIB-II groups are not supported.
Starting with Data ONTAP 7.3.1, IPv6 (RFC 2465), TCP (RFC 4022), UDP (RFC 4113), and ICMP (RFC 2466) MIBs, which show both IPv4 and IPv6 data, are supported.
- Types of SNMP traps in Data ONTAP
SNMP traps capture system monitoring information in Data ONTAP. There are two types of traps in Data ONTAP: built-in and user-defined.
- What a MIB is
A MIB file is a text file that describes SNMP objects and traps. MIBs are not configuration files. Data ONTAP does not read these files and their contents do not affect SNMP functionality.
- What the SNMP agent does
The storage system includes an SNMP agent that responds to queries and sends traps to network management stations.
- How to configure the SNMP agent
You need to configure the SNMP agent on your storage system to set SNMP values and parameters. You can configure your SNMP agent through the command-line interface or with FilerView.
- User-defined SNMP traps
If the predefined built-in traps are not sufficient to create alerts for conditions you want to monitor, you can create user-defined traps in Data ONTAP.
