Re: DDMi - Discover DHCP Clients w/o DHCP Server Discovery
I manage about 32,000 devices discovered, and 14,000 devices inventoried without utilizing my DHCP servers / arp tables / etc. I basically have it set to do it's normal discovery: ping sweeps / etc.
I'm sure that if I had access to ARP tables, the discovery process would work a little better, but I have nothing to complain about and the DDMI server functions just fine for me.
DDMI is set to ping sweep subnets that you define in your device groups. I have about 75 device groups with a bunch of subnets defined. At 30 pings a second, it takes 90 minutes to get through my 'known' network. DDMI will find the new ips for devices if they change, merge them accordingly, etc.
My experience is that it is NOT critical to the success at all of the DDMI.
