Traps
Trap managers are special users of the network who are
given certain rights
maintenance of the network. Trap managers can receive
traps sent from the Switch; they must immediately take
certain actions to avoid future failure or breakdown of the
network.
Traps are messages that alert you of events that occur on
the Switch. The events can be as serious as a reboot
(someone accidentally turned OFF the Switch), or less
serious like a port status change. The Switch generates
traps and sends them to the network manager (trap
managers). The following lists the types of events that can
take place on the Switch.
