What is the SNMP community string??
The “SNMP Community String” is similar to a user ID or password that allows access to a router’s or other device’s statistics. PRTG Network Monitor forwards the community string along with all SNMP requests. If the correct community string is provided, 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 only used by devices that support SNMP V1 and SNMP V2c protocols. SNMP V3 uses safer username/password authentication, along with an encryption key. By convention, most SNMP V1/V2c equipment ships 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 within the device setup.
