Hello,
I'm in the process of migrating an ISC DHCP server to Kea. I'm trying to
re-create a feature that we use in the ISC DHCP config to set a boot file name
if a specific vendor-class-identifier is met. The ISC DHCP share-network looks
like:
shared-network FOOBAR {
allow bootp;
subnet 10.10.10.0 netmask 255.255.255.0 {
# default PXE boot
if substring(option vendor-class-identifier, 0, 20) =
"PXEClient:Arch:00000" {
filename "ipxe/netboot.xyz.kpxe";
} else {
filename "ipxe/netboot.xyz.efi";
}
For Kea I can create the client class just fine, but how can I restrict these
client classes to apply only to this subnet? I have other subnets that use a
different boot file name. It doesn't seem like using "client-class" in the
"subnet4" config would work as that would require a client to meet the
classification, when that's not necessary.
"client-classes": [
{
"name": "ipxe_legacy_netbootxyz",
"test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00000'",
"next-server": "10.10.10.5",
"boot-file-name": "ipxe/netboot.xyz.kpxe"
},
{
"name": "ipxe_efi_netbootxyz",
"test": "substring(option[60].hex,0,20) == 'PXEClient:Arch:00007'",
"next-server": "10.10.10.5",
"boot-file-name": "ipxe/netboot.xyz.efi"
}
],
Thanks,
