Re: [Netdisco] Okay to delete from node_ip table?

[Joseph B. <jh...@cl...>]

Yeah, it’s the anonymizing feature taken to the extreme.  The devices have been disconnecting several times a minute and each time get 2 new IPv6 addresses.  This eventually filled up the router’s TCAM and things started going wonky.  If I search in Netdisco by MAC address, it won’t even load the results because there are too many.  I can load nodes that have a few thousand entries, but I haven’t tested the limit before it errors.  One MAC address has almost a million entries.  These are nodes behaving VERY badly and not something most people should ever see, so I don’t think a feature is needed unless others have run into it too.

Thanks,
Joseph B.

Hi Joseph, it’s fine, go ahead and delete. You could also set archive flag on the records to hide them a bit but still be in the table.

(there is some rotating v6 anonymising feature hosts have and could this be it? if you feel netdisco could benefit from a feature to deal with it, open a ticket)

We’ve had a few nodes lose their minds and rack up thousands of IPv6 entries in Netdisco.  Is it okay for me to delete the entries directly from the node_ip table or will this have unforeseen consequences?
