Use the IFTABLE attribute group to monitor a wide range of network interface information. 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 IFTABLE 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.
ifAdminStatus The desired state of the interface. The testing(3) state indicates that you cannot pass any operational packets. A valid entry is an alphanumeric text string, with a maximum length of 64 characters. Possible values include:
1 = up
2 = down
3 = testing
ifDescr 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. A valid entry is an alphanumeric text string, with a maximum length of 256 characters.
ifIndex A unique value for each interface. Its value ranges between 1 and the value of ifNumber. The value for each interface must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization. A valid entry is an integer of up to four digits.
ifInDiscards The number of inbound packets that were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. You might discard such a packet to free up buffer space. A valid entry is an integer of up to four digits.
ifInErrors The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. A valid entry is an integer of up to four digits.
ifInNUcastPkts The number of subnetwork-broadcast or subnetwork-multicast packets delivered to a higher-layer protocol. A valid entry is an integer of up to four digits.
ifInOctets The total number of octets received on the interface, including framing characters. A valid entry is an alphanumeric text string, with a maximum length of 12 characters.
ifInUcastPkts The number of subnetwork-unicast packets delivered to a higher-layer protocol. A valid entry is an integer of up to four digits.
ifInUnknownProtos The number of packets received through the interface that were discarded because of an unknown or unsupported protocol. A valid entry is an integer of up to four digits.
ifLastChange The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value. A valid entry is an integer of up to four digits.
ifMtu The size of the largest datagram that you can send from or receive on the interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the largest network datagram that you can send from the interface. A valid entry is an integer of up to four digits.
ifOperStatus The current operational state of the interface. The testing(3) state indicates that you cannot pass any operational packets. A valid entry is an alphanumeric text string, with a maximum length of 64 characters. Possible values include:
1 = up
2 = down
3 = testing
ifOutDiscards The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. You might discard such a packet to free up buffer space. A valid entry is an integer of up to four digits.
ifOutErrors The number of outbound packets that could not be transmitted because of errors. A valid entry is an integer of up to four digits.
ifOutNUcastPkts The total number of packets that higher-level protocols requested be transmitted to a subnetwork-broadcast or subnetwork-multicast address, including those that were discarded or not sent. A valid entry is an integer of up to four digits.
ifOutOctets The total number of octets transmitted out of the interface, including framing characters. A valid entry is an alphanumeric text string, with a maximum length of 12 characters.
ifOutQLen The length of the output packet queue (in packets). A valid entry is an integer of up to four digits.
ifOutUcastPkts The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent. A valid entry is an integer of up to four digits.
ifPhysAddress The interface's address at the protocol layer immediately `below' the network layer in the protocol stack. For interfaces that do not have such an address, such as a serial line, this object should contain an octet string of zero length. A valid entry is an alphanumeric text string, with a maximum length of 256 characters.
ifSpecific A reference to MIB definitions specific to the particular media being used to realize the interface. For example, if the interface is realized by an ethernet, then the value of this object refers to a document defining objects specific to ethernet. If this information is not present, its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntactically valid object identifier, and any conformant implementation of ASN.1 and BER must be able to generate and recognize this value. A valid entry is an alphanumeric text string, with a maximum length of 1024 characters.
ifSpeed An estimate of the interface's current bandwidth in bits per second. For interfaces that do not vary in bandwidth or for those where you cannot make an accurate estimation, this object should contain the nominal bandwidth. A valid entry is an integer of up to four digits.
ifType The type of interface distinguished according to the physical/link protocols immediately below the network layer in the protocol stack. A valid entry is an integer of up to four digits. Types include:
1 = other
2 = regular1822
3 = hdh1822
4 = ddn-x25
5 = rfc877-x25
6 = ethernet-csmacd
7 = iso88023-csmacd

11 = starLan
12 = proteon-10Mbit
13 = proteon-80Mbit
14 = hyperchannel
15 = fddi
16 = lapb
