OK, not a debug, but note down at the bottom, CHANGES 51 added. And after a period of time, they go away.

Well crap. Ignore those debugs. Apparently I couldn’t type “neighbours” correctly. Let’s try that again.

Tom, I’m tracking a problem right now with a 6509 and a 7609 that my system is polling….
I can go in and look at the specific device, ports screen, my ports menu bar will show:
Ports
Basic
Details
ARP/NDP Table
FDB Table
Graphs
Minigraphs
Quick Filters
Notice no neighbors or maps.
Sometimes I can manually force a neighbors discovery (./discovery.php –h whatever –m neighbours), and the system will immediately populate… but it looks like something has been recently broken, as watching a debug run of that process doesn’t even show the server even attempt to make a query against the chassis. I even ran that against a Nexus 5548 that does currently show neighbours in the ports menu bar:
Ports
Basic
Details
ARP/NDP Table
FDB Table
Neighbours
Map
Graphs
Minigraphs
Sanitized debugs attached.
…Ron

Code for CDP/LLDP/mapping hasn't changed in ages; likely the 6509 is not providing CDP information...
