IOS DHCP server option 60 for use with SCCM

[hypnocarrot]

Hi

i've hit a little bit of a problem, to do with an SCCM deployment, basically, option 60 ascii "PXEClient" is configured and boots all devices that use UEFI, however, some legacy devices are still requiring SCCM deployment, devices with BIOS's dont PXE boot with option 60 included in DHCP pool, remove this and legacy devices boot. Hence the problem

ip dhcp pool test-pool
   network 192.168.1.0 255.255.255.0
   next-server sccmserverip
   default-router 192.168.1.254
   dns-server dns1 dns2
   netbios-name-server wins1 wins2
   domain-name domain.local
   option 42 ip ntp1 ntp2
   netbios-node-type h-node
   option 66 ascii "sccmserverip"
   option 67 ascii "\smsboot\x64\wdsnbp.com"
   option 60 ascii "PXEClient"
   lease 0 8
  

we need something like, to take into account UEFI(x64), UEFI(x32) and BIOS(x32/64)

option 60 ascii "PXEClient:Arch:00007|PXEClient:Arch:00006|PXEClient:Arch:00000"

but, obviously this doesn't work

any thoughts, is this even possible?

Hi hypnocarrot, 

I'd like to do this too but, as far as I'm aware, it's not currently possible to offer a different bootfile name depending on the client using IOS DHCP. 

A workaround would be to have a DHCP pool for Legacy/BIOS clients offering one bootfile and another pool giving the UEFI bootfile. Not ideal though.
