RFC 1213 MIB II STATISTICS

Description

A textual string containing information about the interface. This string includes the name of the manufacturer, the product name and the version of the hardware interface.

Type (value)

The type of interface, distinguished according to the physical/link protocol(s) immediately below the network layer in the protocol stack. It will have one of the following values:

Table 4-1 Type(value)/Comments

MTU Size

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

Speed

An estimate of the current bandwidth of the interface in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimates can be made, this object contains the nominal bandwidth.

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 It will have one of the following values:

Table 4-2 Administration Status

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

Operation Status

The current operational state of the interface. It will have one of the following values.

Table 4-3 Operation Status

up(1)	Ready to pass packets
down(2)	Not operative
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 delivers 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)

RFC 1284 Ethernet-Like Interface Statistics

Index: A value that uniquely identifies an interface to an Ethernet-like medium.
Alignment Errors: A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.
FCS Errors: A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.
Single Collision Frames: A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision.
Multiple Collision Frames: A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision.
Deferred Transmissions: A count of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy. The count represented by an instance of this object does not include frames involved in collisions.
Late Collisions: The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a packet.
Excessive Collisions: A couple of frames for which transmission on a particular interface fails due to excessive collisions.
Internal MAC Transmit Errors: A count of frames for which transmission on a particular interface fails due to an internal MAC sublayer transmit error.
Carrier Sense Errors: The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface.
Frames Too Long: Account of frames received on a particular interface that exceed the maximum permitted frame size.
Internal MAC Receive Errors: A count of frames for which reception on a particular interface fails due to an internal MAC sublayer receive error
