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 Power-On Self-Test (POST) 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.
♦ New Root This trap indicates that the Switch has
become the new root of the Spanning Tree, the trap is
sent by a bridge soon after its election as the new root.
This implies that upon expiration of the Topology Change
Timer the new root trap is sent out immediately after the
Switch’s selection as a new root.
