18.1 Getting and installing an SNMP agent

There are several SNMP agent which support SMUX or AgentX. We recommend to use the latest version of net-snmp which was formerly known as ucd-snmp. It is free and open software and available at http://www.net-snmp.org/ and as binary package for most Linux distributions. net-snmp has to be compiled with --with-mib-modules=agentx to be able to accept connections from Quagga using AgentX protocol or with --with-mib-modules=smux to use SMUX protocol.

Nowadays, SMUX is a legacy protocol. The AgentX protocol should be preferred for any new deployment. Both protocols have the same coverage.
