Meaning
|
Frames/second
|
Rate of received frames per second.
|
Bytes/second
|
Rate of received bytes per second.
|
Errors/minute
|
Rate of errors (which led to frames being lost) per minute.
|
Discards/minute
|
Rate per minute of packets discarded due to unavailable resources.
|
Total frames
|
Total frames that are received on the interface.
|
Total bytes
|
Total bytes that are received on the interface.
|
Multi/broadcast
|
Total number of multicast or broadcast packets received.
|
Total discards
|
Total number of "No buffers" packets that were discarded even though no errors were detected.
|
No buffers
|
Number of times the driver could not allocate a buffer and a packet was dropped. This might happen when your storage system is very busy. If the count increases continually, it might indicate that a software component is not returning buffers.
|
Non-primary u/c
|
Number of Ethernet frames received for the partner's MAC address after a failover in a cluster configuration.
|
Tag drop
|
Number of tagged frames dropped on an interface that is not configured to support VLAN tagging.
|
Vlan tag drop
|
Number of tagged frames dropped that do not match the VLAN tags configured on the interface.
|
Vlan untag drop
|
Number of untagged frames dropped on an interface that is configured to be part of a VLAN.
|
Runt frames
|
Number of received frames that were less than the minimum size (64 bytes) and had a valid CRC.
|
Long frames
|
Number of received frames that were greater than the maximum size and had a valid CRC.
|
CRC errors
|
Number of packets received with bad CRC.
|
Length errors
|
Number of frames received by the MAC where the actual number of bytes received did not match the length given in the Ethernet header.
|
Code errors
|
The number of frames received by the MAC that had a code error signaled by the Physical (PHY) layer.
|
Dribble errors
|
The number of frames received by the MAC with an alignment error. This is not used for 1000Mb/s operation.

Meaning
|
Frames/second
|
Rate of transmitted frames per second.
|
Bytes/second
|
Rate of transmitted bytes per second.
|
Errors/minute
|
Rate of errors (which led to frames being lost) per minute.
|
Discards/minute
|
Rate per minute of packets discarded due to unavailable resources.
|
Total frames
|
Total frames that are transmitted on the interface.
|
Total bytes
|
Total bytes that are transmitted on the interface.
|
Multi/broadcast
|
Total number of multicast or broadcast packets transmitted.
|
Total discards
|
Total number of packets that were discarded even though no errors were detected. This number is a sum of the "No buffers" and "Queue overflow" statistics.
|
Queue overflow
|
Number of outgoing packets dropped because the driver's queue was full. It might indicate a system problem.
|
No buffers
|
Number of times the driver fail to allocate a buffer for the transmit packet.
|
CRC errors
|
Number of packets transmitted by the MAC with CRC errors. This can happen only when the MAC is not appending the CRC to the transmitted packets.
|
Abort errors
|
Number of packets aborted during transmission. This could be because of a FIFO underrun.
|
Runt frames
|
Number of packets smaller than the minimum frame size (64 bytes) transmitted by the MAC.
|
Long frames
|
Number of packets larger than the maximum frame size transmitted by the MAC.
|
Single collision
|
Number of frames that encountered exactly one collision. Only valid in half-duplex mode.
|
Late collisions
|
Number of collisions that occurred outside the collision window. Only valid in half-duplex mode.
|
Deferred
|
Number of times a packet was aborted by the MAC due to excessive collisions during transmission.
If 16 consecutive collisions occur during transmission of a packet, the transmission is deferred and MAC aborts the packet.
