Configuring DHCP as a priority

[dvtestguy]

I have a C6506 that's configured to get DHCP addresses from a DHCP Pool on a C7513 (NAT), and currently not configured with any type of priority. My problem is; I have a need to generate over 1024 IPTV Streams into the 6506, and obviously see the CPU go up to 85%-plus, and other devices on the network that need DHCP addresses are getting choked.

Any ideas how to set DHCP priorities? Is it in the bandwidth, QOS, ToS bit, load balance???

Thanks...
