DHCP Handout from Cisco 3524 XL EN?

kmcintosh78kmcintosh78 Member Posts: 195
Trying to come up with a solution to the following design.
I have a Cisco ASA 5505 and a Cisco 3524 XL EN. Need to have DHCP handed out from 2 VLAN pulls. One to run the PC, the other to run the VoIP Phones.
I have been doing this on 3560s with no issue, but I have hit a roadblock. I can't seem to build the config on the switch to run the DHCP.
Any chance anyone know how to go about this? Can I hand out DHCP from the ASA?

What I am working on
CCNP Route (Currently) 80% done
CCNP Switch (Next Year)
CCNP TShoot (Next Year)

    Yeah the ASA will do DHCP no problem - if you dont have the license to do 802.1q on the ASA interface then you can setup 2 access ports (voice/data) on your switch and connect them to two ports on the asa configured the same

    here's an example: PC/Phones behind Verizon FIOS/Road Runner

    interface Vlan1
    description Vlan for Voice
    nameif inside
    security-level 100
    ip address
    interface Vlan2
    nameif outside
    security-level 0
    ip address dhcp setroute
    interface Vlan12
    description Vlan for Data
    nameif Data
    security-level 50
    ip address

    global (outside) 1 interface
    nat (inside) 1
    nat (Data) 1
    dhcpd dns
    dhcpd lease 14460
    dhcpd ping_timeout 100
    dhcpd auto_config outside
    dhcpd address inside
    dhcpd dns interface inside
    dhcpd enable inside
    dhcpd address Data
    dhcpd enable Data

    interface Ethernet0/0
    description Connection to Internet Provider
    switchport access vlan 2
    speed 100
    duplex full

    interface Ethernet0/1
    description Data Uplink
    switchport access vlan 12

    interface Ethernet0/2
    description Voice Uplink

    With that though, I can't set up Site to Site VPN tunneling.
