Index (etherStatsIndex)

Unique identifier for this etherStats entry.

Data Source (etherStatsDataSource)

Identifies the source of the data that this etherStats entry is configured to analyze. The source can be any Ethernet interface on this device.

In order to identify a particular interface, this object identifies the ifIndex object instance, defined in RFC 1213 and RFC 1573 [4,6], for the desired interface. For example, if an entry was to receive data from interface number 1, this object would be set to "ifIndex.1".

The statistics in this group reflect all packets on the local network segment attached to the identified interface.

An agent may or may not be able to tell if fundamental changes to the interface media have been made, requiring an invalidation of this entry. For example, a hot-pluggable Ethernet card could be removed and replaced by a token-ring card. In such a case, if the agent knows of the change, it is recommended that you invalidate this entry.

Note: This object may not be modified if the associated etherStatsStatus object is equal to "valid(1)".

Owner (etherStatsOwner)

The entity that configured this entry and therefore using the resources assigned to it.
