Keep track of your entire network with
the SNMP monitoring tool PRTG
The “SNMP community string” is like a user ID or password that allows access to a router's or other device's statistics.
SNMP community strings are used only by devices which support the 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.
