Feature #8574
closedEnable AgentX-support in lldpd using GUI
100%
Description
The lldpd-package provided by the package manager seems to be compiled with AgentX-support, but there is nowhere to activate it using the GUI. An AgentX sub-agent can connect to Net-SNMP and would in this case make LLDP-information available over SNMP.
In the Net-SNMP configuration, AgentX has to be enabled. I suppose this could also be added as a GUI option in the Net-SNMP package, but can for now be added to the Custom Options.
master agentx
I made the following changes, which will add the flag -x
to the lldpd

LLDP information can then be queried using the LLDP-MIB tree at .1.0.8802.1.1.2

The above patch works for me. The Net-SNMP package already adds "master agentx" to /var/etc/netsnmpd.conf by default.
(Edit) - Applied the above patches by hand to three pfSense boxes (all 2.4.something) now. Netdisco (http://netdisco.org/) is happy with the results and shows links. To be honest, the net-snmp package is far better than the built in SNMP GUI and might be worth considering becoming the default or ditch the built in package.
