Configure SNMP Management Client Software

After you have configured a vCenter Server system or a host to send traps, you must configure your management client software to receive and interpret those traps.

http://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.monitoring.doc_50/GUID-D025D87A-E7E5-4747-995B-6FC3BB213B0F.html

Configure the SNMP Agent to Filter Traps
vicfg-snmp.pl --server hostname --username username --password password -n oid_list

From the vSphere CLI, vicfg-snmp.pl --server hostname --username username --password password -n oid_list
oid_list is a list of OIDs for the traps to filter, separated by commas. This list replaces any OIDs that were previously specificed using this command.
For example, to filter out coldStart (OID 1.3.6.1.4.1.6876.4.1.1.0) and warmStart (OID 1.3.6.1.4.1.6876.4.1.1.1) traps, type vicfg-snmp.pl --server hostname --username username --password password -n 1.3.6.1.4.1.6876.4.1.1.0,1.3.6.1.4.1.6876.4.1.1.1
To clear all trap filters, typevicfg-snmp.pl --server hostname --username username --password password -n reset
