To enable AgentX protocol support, Quagga must have been build with the
--enable-snmp=agentx option. Both the
master SNMP agent (snmpd) and each of the Quagga daemons must be
directive should be added. In each of the Quagga daemons,
command will enable AgentX support.
/etc/snmp/snmpd.conf: # # example access restrictions setup # com2sec readonly default public group MyROGroup v1 readonly view all included .1 80 access MyROGroup "" any noauth exact all none none # # enable master agent for AgentX subagents # master agentx /etc/quagga/ospfd.conf: ! ... the rest of ospfd.conf has been omitted for clarity ... ! agentx !
Upon successful connection, you should get something like this in the log of each Quagga daemons:
2012/05/25 11:39:08 ZEBRA: snmp[info]: NET-SNMP version 5.4.3 AgentX subagent connected
Then, you can use the following command to check everything works as expected:
# snmpwalk -c public -v1 localhost .220.127.116.11.18.104.22.168.1 OSPF-MIB::ospfRouterId.0 = IpAddress: 192.168.42.109 [...]
The AgentX protocol can be transported over a Unix socket or using TCP
or UDP. It usually defaults to a Unix socket and depends on how NetSNMP
was built. If need to configure Quagga to use another transport, you can
configure it through
/etc/snmp/quagga.conf: [snmpd] # Use a remote master agent agentXSocket tcp:192.168.15.12:705
