Configuring SNMP Settings
Console version
You can configure the Simple Network Management Protocol (SNMP) on your Switch to:
send traps, or error messages, to one or more management stations
●
define community names, or passwords, to limit access to the Switch●
Set trap destinations
You can monitor significant events on your network by having the Switch send error messages, called traps, to a
network management system or console.
For example, a trap might record errors and packet overflows that
signal network congestion. Along with the status and statistics reporting, traps are invaluable for troubleshooting.
The Switch issues the following traps, which can be identified in an SNMP management application by the Trap
Number.

Switch has received an SNMP packet from an
unauthorized station
The Switch gives you a very simple way to create the list of management stations that you want to receive traps.
Whenever an SNMP management station polls the Switch for information, the Switch stores that station's IP
address information. These learned stations appear in the Set Trap Destinations screen with an attribute of
dynamic. A dynamically learned station can be saved permanently by simply changing its attribute from
dynamic to permanent.
To set the Switch to send traps to different management stations, select Set Trap Destinations from the
Console Main Menu.
The Set Trap Destinations screen appears:
The IP address and subnet mask of all stations currently receiving traps are listed. To add other stations
to the list, fill in the IP Address and IP Mask fields with the correct information.
1.
Toggle through the Attribute field. Your choices are permanent or dynamic. Permanent means the
specified IP address is permanently saved in the Switch's memory until you change it. Dynamic means
that the IP address can be erased when the Switch receives an SNMP packet and learns a new IP
address. Dynamic entries are also erased when the Switch is rebooted.
