    Description

      Hi,

      I have trouble with neighbours after r10477, seems to be mainly with lldp only (I am aware it said implementetd partally in commits node ).

      On every discovery I have this in the events logs for several devices:

      2020-06-11 00:07:52 swi-dc1-core-1 swi-dc1-core-1 Neighbours: 37 deleted, 37 unchanged.
      2020-06-11 00:07:43 hp3810-mf-1 hp3810-mf-1 Neighbours: 1 deleted.
      2020-06-11 00:07:31 rtr-mpls01 rtr-mpls01 Neighbours: 5 deleted.
      2020-06-11 00:03:36 rtr-mpls01 rtr-mpls01 Neighbours: 5 deleted.
      2020-06-11 00:02:40 hp3810-mf-1 hp3810-mf-1 Neighbours: 1 deleted.
      2020-06-11 00:02:17 swi-dc1-core-1 swi-dc1-core-1 Neighbours: 37 deleted, 37 unchanged.

      I am attaching the output of "./poller.php -h device -m neighbours -d" for ostypes; cisco iosxe, arubaos, and hp/aruba provision if that can help for anything.

          Additionally there is escaping trouble, fixed in r10508.

          But if you can, make snmp dump anyway.

          Last Changed - is datetime when entry with neighbour changed (added/removed/etc).

          Autodiscovery - this is an attempt to add new device and store if neighbour already exist.
          This table required for reduce unnecessary attempts to auto-add devices.
          Entries to this table will added anyway, also if xdp autodiscovery disabled - if remote device already in db as "ok" (your case), if not exist as "xdp disabled".

          (Probably need improved popup message for this case).

          Confirm everything is back to normal. I even think I have some more  neighbours then before.

          I just have a question about the popup under "Last Changed": "Remote host <host> (<ip>) successfully added to db. Autodiscovery checked: x ago"

          What exactly is that supposed to be for? I see this only on LLDP and "neighbour" devices I already have added. Also I have "xdp" autodiscovery disabled, so it was not added by that feature.

          Maybe I misunderstood something about it ?

          Hrm, this is not formatting issue, something strange in lldp data.. please attach discovery

          ./discovery.php -d -m neighbours -h <device>

          and better additionally attach your snmp dump from device:

          snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk
          snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk
