Name (ifName)

Textual name of the interface. The value of this object is the name of the interface, as assigned by the local device, and is suitable for use in commands entered at the device console.

Index (ifIndex)

A unique value for each interface, which ranges between "1" and the value of ifNumber. The value for each interface must remain constant from one reinitialization of the entity's network management system to the next reinitialization.

Descriptor (ifDescr)

Textual description of the physical entity. This object contains a string which identifies the manufacturer name, the product name, and the interface hardware/software version.

Type (ifType)

The type of interface.

MTU (ifMtu)

The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that transmit network datagrams, this is the size of the largest network datagram that can be sent on the interface.

Speed (ifSpeed)

An estimate of the interface's current bandwidth, measured in bits per second.

Physical Address (ifPhysAddress)

Address of the interface at its protocol sublayer. The media-specific MIB on the interface must define the bit and byte ordering and format of the value contained by this object.

Admin Status (ifAdminStatus)

Desired state of the interface.

Operational Status (ifOperStatus)

Current operational state of the interface.

Last Change (ifLastChange)

Value of sysUpTime when the interface entered its current operational state. If the current state was entered prior to the last reinitialization of the local network management subsystem, then this object contains a value of "0".
