That is an “SNMP Community String”:

The “SNMP Community string” is like a user id or password that allows access to a router's or other device's statistics.

IPCheck Server Monitor sends the community string along with all SNMP requests.

  • If the community string is correct, the device responds with the requested information.
  • If the community string is incorrect, the device simply discards the request and does not respond.

Note: SNMP Community strings are used only by devices which support SNMPv1 and SNMPv2c protocol. SNMPv3 uses username/password authentication, along with an encryption key.

By convention, most SNMPv1-v2c equipment ships from the factory with a read-only community string set to "public". It is standard practice for network managers to change all the community strings to customized values in the device setup.
