Hi Pete and Jim

I wonder if Network Registrar supports Failover. If so, what's the best way to configure it?

Thank you


Hi Chris,

   Network Registrar certianly  does support the DHCP Failover protocol. We always suggest using

   Simple Failover for which the configuration instructions are available here;

I have a simple question. Does Cisco Prime Network Registrar support IPv6? If so, how do I configure the addresses pools? I currently use regular CNR for the addressing for my cable modems in a cable network and I want to migrate to cisco prime. Is this possible? Do you have any referrence I can review on how to do this?

thank you.


Hi Jorge,

   Absolutely, Prime CNR supports IPv6 since CNR 6.x versions...

   For IPv6 configuration instructions on latest versions of CPNR you should start here;

Hi Pete,

I would like to ask if the CNR can map IP address with users in tue activce directory?  is there integration with active directory?

Hi Jaime, Do you find if CNR can map IP addresses with clients usernames? I'm trying to apply this scenario over a CNR 8.2
