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.

Further information about
SNMP and SNMP monitoring

What is SNMP?

SNMP stands for Simple Network Management Protocol and describes a set of standards for the communication of devices in a TCP/IP network. The great advantage of SNMP is the wide distribution and the support of almost all devices of many different manufacturers.

More details about SNMP can be found here.

Why should I use SNMP monitoring?

Network monitoring with SNMP usually works very reliably, requires hardly any bandwidth and allows you to get an overview of a large part of your network without a large network and CPU load. With a variety of predefined sensors PRTG makes SNMP monitoring especially easy.

How do I get more detailed insights about my network? ?

SNMP gives you a good overview of the performance of your network. For more detailed traffic insights, you can use flow protocols such as NetFlow, jFlow or sFlow, or packet sniffing.
