RFC 1213 MIB II

Title not available (RFC 1213 MIB II)

Field

Description

Network Management ID

A unique ID assigned by the system for the network management of each network interface.

Description

A textual string containing information about the interface.

Type (value)

The type of interface, distinguished according to the physical/link protocols , immediately below the network layer in the protocol stack.

10/100Base-TX can have one of the following values:ethernet-csmacd(6), or iso88023-csmacd(7).

The following values are for other networking products.

MTU Size

The size of the largest datagram which can be sent/received on the interface specified in octets. This value is 1500.

Speed in bits per second

The speed of the 10/100Base-TX card, 10 Mbit/s or 100 Mbit/s.

Station Address

The interface address at the protocol layer immediately below the network layer in the protocol stack. For interfaces which do not have such an address, such as serial line, this object contains an octet string of zero length.

Administration Status

The desired state of the interface. This parameter is set to up(1) and is not configurable. It will have one of the following values:

up(1)	Ready to pass packets
down(2)	Not operative
testing(3)	In test mode

Operation Status

The current operational state of the interface. This value is the same as the hardware status displayed bylanscan(1M). It will have one of the following values.

up(1)	Ready to pass packets
down(2)	Not operative (card is down)
testing(3)	In test mode

Last Change

The value of SysUpTime at the time 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 zero value.

Inbound Octets

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

Inbound Unicast Packets

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

Inbound Non-Unicast Packets

The number of non-unicast (subnetwork-broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.

Inbound Discards

The number of inbound packets that were discarded even though no errors had been detected, to prevent their being delivered to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.

Inbound Errors

The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Inbound Unknown Protocols

The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.

Outbound Octets

The total number of octets transmitted out of the interface, including framing characters.

Outbound Unicast Packets

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.

Outbound Non-Unicast Packets

The total number of packets that higher-level protocols requested be transmitted to a non-unicast (a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.

Outbound Discards

The number of outbound packets that were 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.

Outbound Errors

The number of outbound packets that could not be transmitted because of errors.

Outbound Queue Length

The length of the output packet queue (in packets).
