This step-by-step article describes how to configure traps on a Simple Network Management Protocol (SNMP) service. You can configure the SNMP service to send a trap when it receives a request for information that does not contain the correct community name and does not match an accepted host name for the service.

After you complete these steps, click the Traps tab to continue to the next task.
To create a community, type the case-sensitive community name in the Community name box, and then click Add to list. Repeat this step if you want to create additional community names.
In SNMP Service Properties, click Add on the Traps tab.
In the Host name, IP or IPX address box, type information for the host, and then click Add to list.
Click Add, type the host name, IP address, or IPX address in the appropriate box under SNMP Service Configuration, and then click Add. The host name or address appears in the Trap destinations list. Repeat this step until you have added all of the hosts that you want to add.
Repeat steps 3 and 4 until you configure all the SNMP communities you want, and then click the Security tab to continue to the next task.
In SNMP Service Properties, on the Security tab, click Send authentication trap if you want a trap message sent whenever authentication fails.
Under Accepted community names, click Add.
Under Community Rights, click a permission level for this host to process SNMP requests from the selected community. To view a description of a dialog box item, right-click the item, and then click What's This?.
In the Community Name box, type a case-sensitive community name, and then click Add.
Under SNMP Service Properties, specify whether or not to accept SNMP packets from a host:
To accept SNMP requests from any host on the network, regardless of identity, click Accept SNMP packets from any host.
To limit acceptance of SNMP packets, click Accept SNMP packets from these hosts, click Add, type the appropriate host name, IP or IPX address, and then click Add again.
Although the SNMP service and SNMP security are now ready without rebooting, you should still restart your computer.
IMPORTANT: If you remove all of the community names, including the default name Public, SNMP does not respond to any community names that are presented.
