Max Transfer Unit (ifMTU)

The size of the largest protocol data unit which can be sent/received on the interface, specified in octets. For interfaces that are used for transmitting network protocol data units, this is the size of the largest network pro- tocol data unit that can be sent on the interface.

Speed (ifSpeed)

An estimate of the interface’s current bandwidth in bits per second. For interfaces which do not vary in band- width or for those in which no accurate estimation can be made, this object should contain the nominal band- width.

Physical Address (ifPhysAddress)

This value is the MAC address of the Ethernet port.

Admin Stat (ifAdminStatus)

The desired state of the interface.

•up(1)—The selected interface is ready to pass frames.

•down(2)—The selected interface is not ready to pass frames.

•testing(3)—The selected interface is being tested. No operational frames may be passed in this mode.

Operational Status (ifOperStatus)

The current operational state of the interface.

•up(1)—The selected interface is ready to pass frames.

•down(2)—The selected interface is not ready to pass frames.

•testing(3)—The selected interface is being tested. No operational frames may be passed in this mode.

Last Change (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 will be zero.

Received Octets (ifInOctets)

The number of octets received on the interface, including framing characters.

Received Unicast Packets (ifUcastPkts)

The number of subnetwork-unicast packets delivered to a higher layer protocol.

Received Non-Unicast Packets (ifNUcastPkts)

The number of non-unicast (that is, sub-network-broadcast or sub-network-multicast) packets delivered to a higher layer protocol.
