You can disable an SNMP trap instead of deleting it, if you want a particular SNMP trap to stop sending SNMP notifications but want to save the configuration information for future reference.
Procedure

On the EPM navigation pane, click System Configuration > SNMP.
On the SNMP page, in the Host Address column, click the SNMP manager IP address or host name.
On the Change SNMP Trap Configuration page, in the Enable field, click No.
