collisions Number of messages retransmitted due to an Ethernet collision. This is usually the result
of an overextended LAN (Ethernet or transceiver cable too long, more than two repeaters
between stations, or too many cascaded multiport transceivers). A packet that collides is
counted only once in output packets.
interface resets Number of times an interface has been completely reset. This can happen if packets
queued for transmission were not sent within several seconds. On a serial line, this can be
caused by a malfunctioning modem that is not supplying the transmit clock signal, or by
a cable problem. If the system notices that the carrier detect line of a serial interface is
up, but the line protocol is down, it periodically resets the interface in an effort to restart
it. Interface resets can also occur when an interface is looped back or shut down.
restarts Number of times a Type 2 Ethernet controller was restarted because of errors.
