NOTE:
Defining community can allow management systems in the same community to communicate
with the SNMP Agent. The community name can be seen as the shared password of the network
hosts group. Thus, for the security, we suggest modifying the default community name before
enabling the SNMP Agent service. If the field of community is blank, the SNMP Agent will not
respond to any community name.
