Hello all,
When trying to boot-up an Intel Mohon Peak CRB, it seems that the 'vendor-encapsulated-options' is not treated in the same way as, for example, when I try to boot-up an IBM Appliance Server (with the same dhcpd.conf file).
Our DHCP server:
[root at kteam-infra ~]# /usr/sbin/dhcpd -?
Internet Systems Consortium DHCP Server 4.1.1-P1
I tried to declare the 'vendor-encapsulated-options' as standalone in the dhcpd.conf file:
<...>
# PXE Class
class "PXEClient" {
default-lease-time 1800;
max-lease-time 1800;
}
group {
allow booting;
allow bootp;
next-server 172.25.27.90;
default-lease-time 1800;
max-lease-time 1800;
# Mohon Peak
host mohon_pag {
hardware ethernet 00:80:9F:FF:FF:FC; # ETH0
filename "/bootp/linux/106.000-pre/pxe/pxeloader_mohon";
fixed-address 172.25.27.80;
option vendor-encapsulated-options "S/tel/L2960.fr";
}
}
This end up in the debug logs (with DEBUG=dhcp,dhcpopts,pxe_preboot):

In that case, tcpdump+wireshark show no errors.
I tried also to encapsulate it, with following configuration in the dhcpd.conf:
<...>
# Define vendor space
option space PXE;
option PXE.option-129 code 129 = text;
<...>
group {
allow booting;
allow bootp;
next-server 172.25.27.90;
default-lease-time 1800;
max-lease-time 1800;
# Mohon Peak
host mohon_pag {

filename "/bootp/linux/106.000-pre/pxe/pxeloader_mohon";
fixed-address 172.25.27.80;
option vendor-class-identifier "PXEClient";
vendor-option-space PXE;
option PXE.option-129 "S/tel/L2960.fr";
}
}

In that case, tcpdump+wireshark show an "Unknown suboption 129" in the DHCPOFFER and DHCPACK transactions.
I replaced 'text' by 'string' with the same result.
In both cases, our installer does not see the string "S/tel/L2960.fr".
For iPXE, what should be used ? Encapsulated or not ?
Is there maybe anything to add on iPXE side ?
Any hint is welcome.
Thanks in advance.
Kind regards,
