Statistics for a list of interface entries. There is one entry per IEEE 802.3 like 'interface.'

Index of the interface. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.

The number of frames that are successfully transmitted. This counter is incremented when a frame is successfully transmitted, even if one of the collision counters (following two objects) is also counted. In other words, this count includes transmissions that succeeded after some number of collisions. This count includes multicast and broadcast frames.

The number of frames that are involved in a single collision, and are subsequently transmitted successfully. If this counter is incremented, then the ieee8023FrmsTxOK count will also be incremented AND ieee8023MultipleCollFrms will NOT be incremented.

The number of frames that are involved in more than one collision and are subsequently transmitted successfully. If this counter is incremented, then the ieee8023FrmsTxOK count will also be incremented AND ieee8023SingleCollFrms will NOT be incremented.

The amount of data AND PADDING octets of frames that are successfully transmitted. This counter includes octets in broadcast and multicast frames that are transmitted. This count does not include the address fields, length/type field, and CRC field of the frame. According to Ethernet terminology, it is purely the data field (IP header, etc.).

The number of frames whose transmission was delayed on its first attempt because the medium was busy. Frames involved in collisions are NOT included in this count.

The number of frames successfully transmitted to a multicast address. This counter does not include frames sent to the broadcast address.

The number of frames successfully transmitted to the broadcast address. This counter does not include frames sent to a multicast address.

The number of times that a collision has been detected later than 512 bit times into the transmission of a packet. 512 bit times is 51.2 micro secs. This type of collision is counted twice - both as a late collision and as a regular, ordinary collision.

The number of frames that are not transmitted because of excessive collisions.

The number of frames that would otherwise be transmitted by the station, but could not be sent because of an internal MAC sublayer transmit error. If this counter is incremented, then none of the other counters in this section are incremented. The exact meaning and mechanism for incrementing this counter is implementation dependent. In short, this is the count of errors for which there are no specific counters.

The number of times that carrier sense was lost or never appeared when attempting to transmit a packet. This counter is incremented ONCE per transmission attempt, even if Carrier Sense fluctuates.

The number of frames that deferred for an excessive period of time.

The number of frames that are successfully received. This counter does not include frames received with frame-too-long, FCS, length, or alignment errors, or frames lost because of internal MAC sublayer error. This counter includes broadcast and multicast frames that are received.

The number entry of data and padding octets in frames that are successfully received. This counter does not include frames received with frame-too-long, FCS, length, or alignment errors, or frames lost because of internal MAC sublayer error. This counter includes octets in broadcast and multicast frames that are received. This counter does not include the octets in the address, length/type, and CRC fields.

The number of frames that are successfully received and are directed to an active non-broadcast group address. This counter does not include frames received with frame-too-long, FCS, length, or alignment errors, or frames lost because of internal MAC sublayer error. Only frames for a multicast address that this interface is receiving are counted. Broadcast packets are not included.

The number of frames that are successfully received and are directed to the broadcast group address. This counter does not include frames received with frame-too-long, FCS, length, or alignment errors, or frames lost because of internal MAC sublayer error. Multicast packets are not included.

The number of frames that are received and exceed the maximum permitted frame size. This counter is incremented when the frameTooLong error is returned.

The number of frames that are not an integral number of octets in length and do not pass the FCS check. This counter is incremented when the alignmentError status is returned to the LLC.

The number of frames that are an integral number of octets in length and do not pass the FCS check. This counter is incremented when the frameCheckError status is returned to the LLC.

The number of frames with a length field value between the minimum unpadded LLC data size and the maximum allowed LLC data size inclusive, and which do not match the number of LLC data octets received. The counter also contains frames with a length field value less than the minimum unpadded LLC data size.

The number of frames with a length field value greater than the maximum allowed LLC data size. If true 802.3 is followed for layer management, then this counter will be incremented for every IP or ARP frame received that uses the Ethernet encapsulation method. Both IP and ARP use type field values that will cause this counter to be incremented, showing a high error rate.

The number of frames that would otherwise be received by the station, but could not be accepted because of an internal MAC sublayer receive error. If this counter is incremented, then none of the other counters in this section are incremented. The exact meaning and mechanism for incrementing this counter is implementation dependent. This is the count of other errors.

Reinitializes the MAC and PLS (physical layer signaling). All MIB counters are set to 0. The states of the status variables (described below) are as follows: - The receive and transmit Layer Management state variables (receiveEnabled and transmitEnabled) are set to enable reception and transmission of frames. - The promiscuous receive function is disabled. - Multicast reception is disabled. Enumeration: 'initialize': 1, 'uninitialize': 2.

This variable combines the enable ieee8023PromRx, disable ieee8023PromRx, and read ieee8023PromStatus MAC actions. Setting this variable to enabled causes the interface to accept frames regardless of their destination address. When enabled, all received frames increment all counters as though those frames were directed to this station. Frames can be promiscuously received only if the ieee8023MacSubLayerStatus variable is also set to enabled(1). Enumeration: 'disabled': 2, 'enabled': 1.

This variable causes the MAC sublayer to enter the normal operational state at idle. The PLS is reset by this operation. It is accomplished by setting receiveEnabled and transmitEnabled to true. Setting this variable to enabled(1) enables the MAC sublayer to both receive and transmit frames. Setting this variable to enabled(1) will also set the ieee8023TransmitStatus variable to enabled(1). Similarly, setting this variable to disabled(2) will also set ieee8023TransmitStatus to disabled(2). Modifying this variable does not change the state of any other variables. If the variable is set to disabled(2), then any current transmission/reception is completed before the transmission/reception process is disabled. The value returned when this variable is read is the logical and of the receiveEnabled and transmitEnabled MAC internal state variables. If both are in the enabled state, then enabled(1) is returned; otherwise disabled(2) is returned. Enumeration: 'disabled': 2, 'enabled': 1.

This variable enables the MAC sublayer to be explicitly enabled/disabled for transmitting frames. If a frame is being transmitted when this variable is set to disabled(2), that transmission is completed. Note that ieee8023MACSubLayerStatus has an effect on this variable. Enumeration: 'disabled': 2, 'enabled': 1.

Enables/disables reception of multicast frames. To actually receive multicasts, both this variable AND ieee8023MacSubLayerStatus must be set to enabled. Enumeration: 'disabled': 2, 'enabled': 1.

This object contains the MAC station address (i.e., the Ethernet address).

The number of times that the SQE TEST ERROR status was received.

A table containing information on collision activity.

The entry corresponding to the number of attempts made before a frame was successfully transmitted. The range is from 1 to 15.

The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.

The number of frames that were retransmitted a specific number of times.

A table containing information on group addresses. There are five entries in the table.

The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.

A group address to which this Ethernet-like interface responds.

Type of group address. Setting this object to the value invalid(2) invalidates the corresponding entry in the ieee8023GroupTable. That is, it effectively disassociates the interface identified with said entry from the group address identified with said entry. Whether the agent removes an invalidated entry from the table is an implementation-specific matter. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use. Proper interpretation of such entries requires examination of the relevant ieee8023GroupType object. Enumeration: 'other': 1, 'invalid': 2.
