I have a 6509 with many VLANs and a seperate DHCP server to provide addresses. I need to create an additional VLAN (VLAN 20) and I would like to use the 6509 as the DHCP Server for the new VLAN.
I know to set up:
ip dhcp excluded-address 20.20.20.1 20.20.20.5
!
ip dhcp pool VLAN-20
network 20.20.20.0.0 255.255.255.0
default-router 20.20.20.1
But what I am unsure of is how do I make sure the 6509 does NOT respond to DHCP requests on any of the existing VLANs?

It won't. It will only hand out addresses for the 20.20.20.x network ie. clients in that vlan.
Having said that it is not a good idea to use the 6500 this way. I would always recommend using a separate DHCP server such as Windows or Unix. 6500 switches and switches in general are best left to do what they are meant to do ie. switch at L2 and L3. In addition, i'm not sure about this, but i suspect this would have to be done in software and the less you do in software on a hardware switch, especially something like the 6500, the better.
