2 Special OIDs

Some of the most used SNMP OIDs are translated automatically to a numeric representation by Zabbix. For example, ifIndex is translated to 1.3.6.1.2.1.2.2.1.1, ifIndex.0 is translated to 1.3.6.1.2.1.2.2.1.1.0.

The table contains list of the special OIDs.

Special OID Identifier Description
ifIndex 1.3.6.1.2.1.2.2.1.1 A unique value for each interface.
ifDescr 1.3.6.1.2.1.2.2.1.2 A textual string containing information about the interface.This string should include the name of the manufacturer, the product name and the version of the hardware interface.
ifType 1.3.6.1.2.1.2.2.1.3 The type of interface, distinguished according to the physical/link protocol(s) immediately 'below' the network layer in the protocol stack.
ifMtu 1.3.6.1.2.1.2.2.1.4 The size of the largest datagram which can be sent / received on the interface, specified in octets.
ifSpeed 1.3.6.1.2.1.2.2.1.5 An estimate of the interface's current bandwidth in bits per second.
ifPhysAddress 1.3.6.1.2.1.2.2.1.6 The interface's address at the protocol layer immediately `below' the network layer in the protocol stack.
ifAdminStatus 1.3.6.1.2.1.2.2.1.7 The current administrative state of the interface.
ifOperStatus 1.3.6.1.2.1.2.2.1.8 The current operational state of the interface.
ifInOctets 1.3.6.1.2.1.2.2.1.10 The total number of octets received on the interface, including framing characters.
ifInUcastPkts 1.3.6.1.2.1.2.2.1.11 The number of subnetwork-unicast packets delivered to a higher-layer protocol.
ifInNUcastPkts 1.3.6.1.2.1.2.2.1.12 The number of non-unicast (i.e., subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
ifInDiscards 1.3.6.1.2.1.2.2.1.13 The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
ifInErrors 1.3.6.1.2.1.2.2.1.14 The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.
ifInUnknownProtos 1.3.6.1.2.1.2.2.1.15 The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.
ifOutOctets 1.3.6.1.2.1.2.2.1.16 The total number of octets transmitted out of the interface, including framing characters.
ifOutUcastPkts 1.3.6.1.2.1.2.2.1.17 The total number of packets that higher-level protocols requested be transmitted, and which were not addressed to a multicast or broadcast address at this sub-layer, including those that were discarded or not sent.
ifOutNUcastPkts 1.3.6.1.2.1.2.2.1.18 The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast or broadcast address at this sub-layer, including those that were discarded or not sent.
ifOutDiscards 1.3.6.1.2.1.2.2.1.19 The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.
ifOutErrors 1.3.6.1.2.1.2.2.1.20 The number of outbound packets that could not be transmitted because of errors.
ifOutQLen 1.3.6.1.2.1.2.2.1.21 The length of the output packet queue (in packets).
