In addition, you can also set an IP Address for a gateway router.
This becomes necessary when the network management station
is located on a different IP network from the Switch, making it
necessary for management packets to go through a router to
reach the network manager, and vice-versa.
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 SNMP Community Strings in the
Switch and set the access rights of these Community Strings. In
addition, a VLAN may be designated as a Management VLAN.

Traps

Note: 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 recipient).
Trap recipients are special users of the network who are given
certain rights and access in overseeing the maintenance of the
network. Trap recipients will receive traps sent from the Switch;
they must immediately take certain actions to avoid future
failure or breakdown of the network.
You can also specify which network managers may receive traps
from the Switch by entering a list of the IP addresses of
authorized network managers.
addresses, and four corresponding SNMP community strings can
be entered.
