The SNMP agent included with vCenter Server can be used to send traps when vCenter Server starts and when an alarm is triggered on vCenter Server. The vCenter Server SNMP agent functions only as a trap emitter and does not support other SNMP operations, such as receiving GET, GETBULK, and GETNEXT requests.
vCenter Server can send SNMP v1 traps to other management programs. You must configure your management server to interpret the SNMP traps sent by vCenter Server.
To use the vCenter Server SNMP traps, configure the SNMP settings on vCenter Server and your management client software to accept the traps from vCenter Server.
The traps sent by vCenter Server are defined in VMWARE-VC-EVENT-MIB.mib.
