LLDP daemon package



  • This topic is for information on the lldpd package.

    Version history:

    • 0.9.4  Initial release

    • 0.9.9  Update to lldpd version 0.9.9



  • Is this in regard to LADVD? Its working pretty good for me.



  • It's about the (new) pfSense lldpd package. Lldpd is similar to LADVD but is a but more up to date and compliant with 802.1ab.


  • LAYER 8 Global Moderator

    Looking forward to it - what kind of timeline to when be available?  Any hints?



  • The pr is in. Reviews are complete, but not sure how long before it would appear in the package repos though. Folks are busy. :)



  • Now showing up as a package.

    lldpd provies support for the 802.1ab Link Layer Discovery Protocol (LLDP), as well as support for several proprietary discovery protocols including Cisco Discovery Protocol (CDP), Extreme Discovery Protocol (EDP), Foundry Discovery Protocol (FDP), and Nortel Discovery Protocol (NDP / SONMP).

    Grabbing it now ;)



  • Looking good, one slight issue, marked in red :-

    I am seeing that as well… But is it just showing you subtype along with the ID?



  • I can't see ifname anywhere, wondering if it is a script error.

    what do you mean you can not see it.. its right here in your output

    "Port Subtype = Interface name, Id: gi1"

    subtype is interface name or ifname ;)

    It just looked a little odd :)


  • LAYER 8 Global Moderator

    I don't think its any sort of "issue"… But would be slicker looking if was broken out into the subtype line vs listed on the port id is all..



  • Just FYI, the version of lldpd currently distributed for pfSense is 0.9.4 because this was the version available in FreeBSD Ports at the time the package was introduced. The current version of lldpd is 0.9.9, which has just been committed to FreeBSD Ports. Movement into the pfSense repo is pending.



  • @johnpoz:

    I can't disagree, however the format of status data is from upstream rather than the pfSense package. The output is directly from the command lldpcli show neighbors.



  • Ah i was trying to figure out how you were getting the output.

  • The status page code is pretty simple. You can see it in /usr/local/www/lldpd_status.php.



  • Is it also possible to add VLAN information?

    And would be nice if next to the port name also I the interface name is mention.

    You do see vlan info:-

    Unless you mean from pfSense:-

  • Yes I mean of pfsense. That’s why I have installed the packages lldpd on pfsense. And if I connect a fluke network analyzer at the ports of pfsense, I don't get VLAN information anywhere.
