24-port NWay Ethernet Switch User’s Guide
26 Switch Management
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.
♦ 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.
♦ Topology Change A Topology Change trap is sent by the
Switch when any of its configured ports transitions from the
Learning state to the Forwarding state, or from the
Forwarding state to the Blocking state. The trap is not sent if
a new root trap is sent for the same transition.

Удалено: 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.
<#>System resets¶
<#>Errors¶
<#>Status changes¶
<#>Topology changes¶
<#>Operation¶
You can also specify which
network managers may
receive traps from the Switch
by setting a list of IP
Addresses of the authorized
