ESX/ESXi includes an SNMP agent embedded in hostd that can both send traps and receive polling requests. such as GET requests. This agent is referred to as the embedded SNMP agent. By default, the embedded SNMP agent is disabled. To enable it, you must configure it using the vSphere CLI command vicfg-snmp. In this video I'll show you how to enable the SNMP agent.
This video is also added to my iTunes channel which can be found at Online VMware Training. It looks great on an iPad.
