SNMP

The SNMP frontend acts as an intermediate daemon between the Net-SNMP daemon (snmpd) and the Clixon backend. Clixon-snmp communicates over the AgentX protocol to snmpd typically via a UNIX socket, and over the internal IPC protocol to the Clixon backend.

Use Net-SNMP version 5.9 or later

To set up AgentX communication between clixon_snmp and snmpd a Unix or TCP socket is configured. This socket is also configured in Clixon (see below). An example /etc/snmpd/snmpd.conf is as follows::

master agentx agentaddress 127.0.0.1,[::1] rwcommunity public localhost agentXSocket unix:/var/run/snmp.sock agentxperms 777 777

It is necessary to ensure snmpd does not to load modules implemented by Clixon. For example, if Clixon implements the IF-MIB and system MIBs, snmpd should not load those modules. This can be done using the "-I" flag and prepending a "-" before each module::

-I -ifTable -I -system_mib -I -sysORTable

Net-snmp must be started via systemd or some other external mechanism before clixon_snmp is started.

To build the snmp support, netsnmp is enabled at configure time. Two configure options are added for SNMP:

--enable-netsnmp Enable SNMP support.
--with-mib-generated-yang-dir For tests: Directory of generated YANG specs (default: $prefix/share/mibyang)
