Description
Ethernet Link
Speed
Indicates if the Ethernet port is operating at 10 Mbps or 100 Mbps
Interface Counters
In Octets
Octets received on the Ethernet interface
In Ucast Packets
Unicast packets received on the Ethernet interface
In NUcast Packets
Non-unicast packets received on the Ethernet interface
In Discards
Inbound packets received on the Ethernet interface but discarded
In Errors
Inbound packets that contain errors (does not include In Discards)
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 that experienced exactly one collision
Multiple Collisions
Successfully transmitted frames that 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
