Keep track of your entire network with
the SNMP monitoring tool PRTG
In SNMP (Simple Network Management Protocol), community strings act as a form of authentication between the SNMP client and the SNMP agent.
The “SNMP community string” is like a user ID or password that allows access to the SNMP agent, for example, a router's, firewall’s, or other network device's statistics.
SNMP strings are used only by devices which support the SNMPv1 and SNMPv2c version of SNMP. SNMPv3 uses username/password authentication, along with an encryption key.
Most SNMPv1 and SNMPv2 equipment ships from the factory with a default community string set to the read-only community string “public”, instead of the “private” read-write community string. It is standard practice for network administrators to configure SNMP by changing all the community strings to customized values in the SNMP settings during device setup.
Next to the read-only (RO) and read-write (RW) community strings, there’s also the trap community string. This string is used to specify the community string that an SNMP agent will use when sending SNMP trap messages to the SNMP client. Traps are asynchronous notifications from the agent to the client about certain events or conditions.

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.
