ATTABLE attributes

Use the ATTABLE attribute group to monitor the mapping of NetworkAddresses, such as IP addresses, to physical addresses. The Management Information Base (MIB-II) detailed in RFC1213 for use with network management protocols in TCP/IP-based internets establishes and defines the attributes of this group.

The ATTABLE attributes are available for the SNMP Data Provider.


Agent Name Identifies the SNMP host name relating to a particular sample of data. A valid entry is an alphanumeric text string, with a maximum length of 64 characters.

atIfIndex The interface on which this entry's equivalence is effective. The interface identified by a particular value of this index is the same interface that is identified by the same value of ifIndex. A valid entry is an integer of up to four digits.

atNetAddress The NetworkAddress corresponding to the media-dependent physical address. A valid entry is an alphanumeric text string, with a maximum length of 32 characters.

atPhysAddress The media-dependent physical address. Setting this object to a null string (one of zero length) makes the corresponding entry in the atTable object incorrect. That is, it effectively disassociates the interface identified with said entry from the mapping identified with said entry. It is an implementation-specific matter as to whether the agent removes an unusable entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant atPhysAddress object. A valid entry is an alphanumeric text string, with a maximum length of 256 characters.
