to the shared nature of Ethernet. Excessive collisions show
excessive utilization of the network.
! Tx Abort Packets – When the router transmits a packet and a
collision occurs, the router will wait a random period and try to
retransmit the packet. If a collision occurs 16 times in a row, the
transmission will be aborted and be logged by this counter. An
aborted packet shows extremely heavy utilization of the network.
! Tx Underrun Packets – Runt packets. The number of packets
transmitted by the router that are less than the allowed 64 octets
minimum length. Underrun packets occur due to jam signals
generated by collisions, backpressure, etc.
! Rx Packets – the number of valid packets received by the router.
! Rx Bytes – the total number of bytes contained in the valid
packets received by the router.
! Rx Unknown Packets – the number of packets received by the
router that were of an unsupported protocol.
! Rx Discard Packets – the number of packets dropped by the
router.
! Rx Error Packets – the number of invalid packets received by the
router. This hardware counter shows the sum of CRC, FAE,
Overrun, MPA and DFR error packets.
! Rx CRC Packets – the number of packets received that failed the
CRC checksum test.
! Rx FAE Packets – Frame Alignment Error. The number of
packets received that does not end on a byte boundary and the
CRC does not match.
! Rx Overrun Packets – the number of packets received that
exceed the 1518 octet maximum length imposed on Ethernet
packets. Overrun packets are generated by some proprietary
software applications.
