ifNumber

The number of network interfaces (regardless of their current state) present on this system.

ifTable

A list of interface entries. The number of entries is given by the value of ifNumber.

ifEntry

An entry containing management information applicable to a particular interface.

ifIndex

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 interface hardware/software.

The type of interface. Additional values for ifType are assigned by the Internet Assigned Numbers Authority (IANA), through updating the syntax of the IANAifType textual convention.
