     - the number of unicast packets received by the port.
  • Unicast packets outbound
     - the number of unicast packets sent by the port.
  • Non-unicast packets inbound
     - the number of multicast packets received by the port.
  • Non-unicast packets outbound
     - the number of multicast packets sent by the port.
  • Packets discards inbound
     - the number of inbound packets that were discarded.
  • Packets discards outbound
     - the number of outbound packets that were discarded.

     - the number of inbound packets that contain errors.
  • Packets with errors outbound
     - the number of outbound packets that contain errors.
  • Unknown protocol packets inbound
     - the number of inbound packets with unknown protocols.
Media Counters
Indicates the counters that allow you to view the status of these elements:
  • Alignment errors
     - the number of frames received that are not an integral number of octets in length.
  • FCS errors

  • Single collisions
     - the number of single collisions.
  • Multiple collisions
     - the number of multiple collisions.
  • SQE test errors
     - the number of times that the SQE TEST ERROR message is generated.
  • Deferred transmissions
     - count of transmissions deferred by busy network.
  • Late collisions
     - the number of late collisions.
  • Excessive collisions
     - the number of frames for which transmission fails due to excessive collisions.
  • MAC transmit errors
     - the number of frames that failed to transmit due to an internal MAC sublayer transmit error.
  • MAC receive errors
     - the number of frames that failed to be received due to an internal MAC sublayer receive error.
  • Carrier sense
     - the number of times the carrier sense condition was lost or never asserted when attempting to transmit a frame.
  • Frame too long
     - the number of frames received that exceed the maximum permitted frame size.
