Configure the vCenter Server Appliance for SNMP v1 and v2c

When you configure the vCenter Server Appliance SNMP agent for SNMP v1 and v2c, the agent supports sending notifications and receiving GET requests.

In SNMP v1 and v2c, community strings are namespaces that contain one or more managed objects. Namespaces can act as a form for authentication, but this does not secure the communication. To secure the communication, use SNMP v3.
