What would be  a reasonable size/number of subnets for behind each CAS, CAM, ACS etc capabilities by model, theoretical limits etc. If someone can give some hypothetical figures for say a network with 5000 users and say 400 switches to include say 5-10 actual layer 3 devices....so I can get something of an idea..I am most interested in the

Layer 2 Out of Band Virtual Gateway.
