DHCP server scan

$

I'm running IPAM 3.0 and am having trouble updating IPAM with my DHCP scope definitions.

 

I had the following scopes originally defined on the DHCP server and when I first added the server to IPAM, it scanned it and picked them up and everything looked good.

 

192.168.1.0/25

192.168.1.128/25

 

Time passes, things change, we now need a /24 subnet in place of the two /25s, so I delete the two scopes on the DHCP server and create a new one:

 

192.168.1.0/24

 

I let IPAM do its default scans every 4 hours, and nothing changes to indicate it's registered this change.

So I go in and delete the two scopes in IPAM, and manually run a DHCP server scan. Result... nothing shows up in "Discovered Subnets".

The two /25 subnets are no longer in my subnets list in IPAM.

 

Am I missing a step somewhere or misunderstanding the process?

 

What should I do for IPAM to pick up the newly defined scope/subnet?

 

Thanks,

Joubin
