Understanding SNMP when used with a vFiler unit

About SNMP

SNMP is not supported on individual vFiler units; it is supported only on the hosting storage system. You can enable SNMP on the hosting storage system to collect data about vFiler units.

About vFiler unit data in the standard MIB and Data ONTAP custom MIB

In the standard Management Information Base (MIB), all vFiler unit data is global. It pertains to the sum of data from all vFiler units on the storage system, with the following exceptions:

Statistics related to network interfaces are for the interfaces in the default IPspace.
TCP statistics include data only from the connections and listen sockets in the default vFiler unit.
UDP statistics include data only from sockets in the default vFiler unit.
Quota information is gathered for each volume. If the hosting storage system or a vFiler unit owns a volume with quotas, quota information is provided for the hosting storage system or vFiler unit owning the volume. If a vFiler unit owns qtrees in a volume that it does not own, no quota information is provided for the vFiler unit.

In the Data ONTAP custom MIB, a group named vFiler is included. It is for per-vFiler unit information, such as the MultiStore license, IP address, protocols allowed, and so on.
