I think that's why a lot of organisations are not keen on stateless IPv6 address assignment but are keener on DHCPv6. I personally would just like an event driven (no SNMP polling...) method that lets me log address<->MAC address usage.
Whilst polling is awkward, event-driven has disadvantages too; specifically, high-rate changes (power outages).
We only have ~3000 hosts so we will be fine, plus event driven (for this purpose) is easy enough to handle via buffering. It's not like you need real-time data, just "one minute late" data. I don't know about you, but we usually get our AUP notices days after the event :)
FWIW I changed our ARP polling to use an "expect" script against out Cisco 6500s, because the SNMP ipNetToMedia table is sloooowwwwww when it gets >20k entries, but the CLI table is sorted in hardware-order, and is thus fast.
Worth remembering....don't happen to have a sensible Expect+Net::SSH setup there I can 'borrow'?
I would ask for ideas, but this is all getting hugely OT.
Ideas for what?
To keep this thread interesting, but it's FreeRADIUS content pretty much has reached zero and I'm waiting for someone to grumble :) Cheers -- Alexander Clouter .sigmonster says: Satire is tragedy plus time. -- Lenny Bruce
