For security, you can set in the Switch a list of IP Addresses of the
network managers that you allow to manage the Switch. You can
also change the default Community Name in the Switch and set
access rights of these Community Names.
Traps
Trap managers are special users of the network who are given
certain rights and access in overseeing the 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
