In Unknown Protos Inbound packets with unknown protocol
Out Octets Octets sent on the Ethernet interface
Out Ucast Packets Unicast packets sent on the Ethernet interface
Out NUcast Packets Non-unicast packets sent on the Ethernet interface
Out Discards Outbound packets discarded
Out Errors Outbound packets that contain errors
Media Counters
Alignment Errors Frames received that are not an integral number of octets in length
FCS Errors Frames received that do not pass the FCS check
Single Collisions Successfully transmitted frames which experienced exactly one collision
Multiple Collisions Successfully transmitted frames which experienced more than one collision
SQE Test Errors Number of times SQE test error message is generated
Deferred Transmissions Frames for which first transmission attempt is delayed because the medium is busy
Late Collisions Number of times a collision is detected later than 512 bit-times into the transmission of
a packet
Excessive Collisions Frames for which transmission fails due to excessive collisions
MAC Transmit Errors Frames for which transmission fails due to an internal MAC sublayer transmit error
Carrier Sense Errors Times that the carrier sense condition was lost or never asserted when attempting to
transmit a frame
Frame Too Long Frames received that exceed the maximum permitted frame size
MAC Receive Errors Frames for which reception on the Ethernet interface failed due to an internal MAC
sublayer receive error
