I was wondering was anyone ever successful in setting up IAS with a Cisco Catalyst 6605 we have several VLAN and one of those VLAN is for the production network and the other one is for business users. Of course they both have access to each other. Here the thing their both on separate subnets for the business users we will be using a 10.x.x.x network and production will be using a 172.16.x.x network. Current we all are on the 172.16.x.x network, so essentally go I am think I will need two DHCP server or can I have one and use a superscope to handle both networks. Between the business users and production users they will be logging onto two different domains. I hope that will identify which IP address to give out to which users pending on which domains they would login to. Any document or guidiance is greatly appreciated.
