TP-Link Auranet EAP115-Wall User Manual page 55

Set Source: Defines the IP address (for example, 10.10.10.1) or subnet for
management systems that can serve as Set Community to read and
write the SNMP information of this device. The format of subnet is "IP
address/bit" (such as 10.10.10.0/24). The default is 0.0.0.0, which
means all hosts can read and write the SNMP information of this
device.
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.
