Abnormally Heavy Traffic/Packet Collision Count

⇒

Problems of this type can have many causes. However, if the LED indicators on your

Alloy 16/24 Gigabit switch show such problems, check that network cards used in
your system are functioning correctly. Faulty Network Adapters can propagate high
levels of ‘runt’ (corrupted) packets onto the network
