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)
