You can also specify which network managers may receive
traps from the Switch by setting a list of IP Addresses of
the authorized network managers.
Trap managers are special users of the network who are
given certain rights and access in overseeing the
maintenance of the network. Trap managers will receive
traps sent from the Switch; they must immediately take
certain actions to avoid future failure or breakdown of the
network.
The following are trap types a trap manager will receive:
♦
Cold Start This trap signifies that the Switch has
been powered up and initialized such that software
settings are reconfigured and hardware systems are
rebooted. A cold start is different from a factory reset.
♦
Warm Start This trap signifies that the Switch has been
rebooted, however the POST (Power On Self-Test) is
skipped.
♦
Authentication Failure This trap signifies that
someone has tried to logon to the switch using an
invalid SNMP community name. The switch
automatically stores the source IP address of the
unauthorized user.
