The Errors table displays the following:
The Receive Errors table displays the following:
Ucast Pkts Sent Displays the number of unicast packets sent through the interface.
Ucast Pkts Received Displays the number of unicast packets received through the interface.
Bcast Pkts Sent Displays the number of broadcast packets sent through the interface.
Bcast Pkts Received Displays the number of broadcast packets received through the interface.
Packet Fragments Displays the number of packet fragments transmitted or received through the
interface.
Jabber Pkts Displays the number of packets transmitted through the interface larger than
the MTU.
Bad Pkts Received Displays the number of bad packets received through the interface.
Collisions Displays the number of collisions over the selected interface.
Late Collisions A late collision is any collision that occurs after the first 64 octets of data have
been sent. Late collisions are not normal, and usually the result of out of
specification cabling or a malfunctioning device.
Excessive Collisions Displays the number of excessive collisions. Excessive collisions occur when the
traffic load increases to the point a single Ethernet network cannot handle it
efficiently.
Drop Events Displays the number of dropped packets transmitted or received through the
interface.
Tx Undersize Pkts Displays the number of undersized packets transmitted through the interface.
Oversize Pkts Displays the number of oversized packets transmitted through the interface.
MAC Transmit Error Displays the number of failed transmits due to an internal MAC sublayer error
(that’s not a late collision), due to excessive collisions or a carrier sense error.
MAC Receive Error Displays the number of received packets that failed due to an internal MAC
sublayer (that’s not a late collision), an excessive number of collisions or a carrier
sense error.
Bad CRC Displays the CRC error. The CRC is the 4 byte field at the end of every frame. The
receiving station uses it to interpret if the frame is valid. If the CRC value
computed by the interface does not match the value at the end of frame, it is
considered as a bad CRC.
Rx Frame Errors Displays the number of frame errors received at the interface. A frame error
occurs when data is received, but not in an expected format.
Rx Length Errors Displays the number of length errors received at the interface. Length errors are
generated when the received frame length was either less or over the Ethernet
standard.
