Reported for interfaces
Description the conflict that occurs when multiple packets of data occur simultaneously from
different sources on a single transmission line
On a LAN, several devices share the cable. If several devices send a packet almost
simultaneously on a strand, a collision is created on that strand and each packet
will need to be resent by its source machine. Collisions are normal for Ethernet;
however, if there are too many of them (close to the network traffic), the strand
houses too many machines or one machine on this segment is badly configured.
Units collisions per hour
Default
thresholds
none
Points to check too many machines on the strand or the network board
