I’ve got 3 NAS servers, 2 with FreeNAS 11.2, 1 with TrueNAS 13.0U6. Out of all 3, only 1 of the FreeNAS 11.2 servers appears to be doing LLDP (using ladvd?) properly, the other two aren’t. All 3 servers are on the same switch (Juniper EX series with JunOS 21.4) that is my go-to point for “is LLDP working.”
I suppose I need to define what I mean by “is LLDP working” - correctly showing the interface name and hostname in “show lldp neighbors” on the Juniper switch. The one that works shows “ixl0” and “ixl1”, the one that doesn’t, I get a MAC address and that’s it. I can’t see anything in particular that would make it work on one and not another.
Is there some magic setting I have missed to get FreeNAS/TrueNAS to always send out the correct format packets?
On the “failing” servers, ladvd is sending out packets like this:
