2 dhcp pools, 2 VLANs

All,

I have an ASA 5505 w/security plus license, a 3560 8 port switch and an 1131 AP. The ASA will have an outside static IP and a L2L tunnel back to HQ. I need two VLANs, 1 for our company data and 1 for guest traffic. I'm curious as to where I should setup the dhcp pools. Should they be on the switch or on the ASA? I do not have a server at this location so I have to use one of these devices for dhcp. Anyone have any ideas and/or config examples? Thanks in advance.

Is the 3560 acting as a L2 or L3 switch ie. your 2 vlans, are they being routed on the 3560 or the ASA ?

Is there a way to do it on both? If not, I would rather have the switch do the routing.

Well if your 3560 is doing the inter-vlan routing -

ip dhcp-excluded address 192.168.100.1 192.168.100.10

ip dhcp-excluded address 192.168.101.1 192.168.101.10

ip dhcp pool vlan100

network 192.168.100.0 255.255.255.0

default-router 192.168.100.1

dns-server x.x.x.x

ip dhcp pool vlan 101

network 192.168.101.0 255.255.255.0

default-router 192.168.101.1

dns-server x.x.x.x
