That is how it worked for me
root at debian:~# more /etc/dhcpd6.conf
option space docsis code width 2 length width 2 hash size 17;
option docsis.device-type code 2 = string;
option docsis.tftp-servers code 32 = array of
ip6-address;
option docsis.cablelabs-configuration-file code 33 = text;
option docsis.cablelabs-syslog-servers code 34 = array of
ip6-address;
option docsis.device-id code 36 = string;
option docsis.time-servers code 37 = array of
ip6-address;
option docsis.time-offset code 38 = signed integer 32;
option docsis.PKTCBL-CCCV4 code 2170 = { integer 16,
integer 16, ip-address, integer 16, integer 16, ip-address};
option vsio.docsis code 4491 = encapsulate docsis;
and in the cm subnet.... 1 is Suboption, 4 is Length (same for suboption 2).
option docsis.PKTCBL-CCCV4 1 4 255.255.255.255 2 4 255.255.255.255;

Subject: ISC Dhcp and CableLabs vendor specific option 2171
Hi,
I'm trying to configure the ISC dhcp server (4.2.3) to hand out option
2171 for cable modems.
I am using a configuration file like this:
option space docsis code width 2 length width 2 hash size 100; option
docsis.tftp-servers code 32 = array of ip6-address; option
docsis.cablelabs-configuraiton-file code 33 = text; option
docsis.syslog-servers code 34 = array of ip6-address; option
docsis.time-servers code 37 = array of ip6-address; option
docsis.time-offset code 38 = signed integer 32; option docsis.ip-prev code
39 = unsigned integer 8;
option space cccv6 code width 2 length width 2 hash size 100; option
cccv6.primary-dhcp code 1 = ip6-address; option cccv6.prov-server code 3 = {
ingeger 8, text }; option cccv6.krb-realm code 6 = text;
option docsis.cccv6 code 2171 = encapsulate cccv6; option vsio.docsis code
4491 = encapsulate docsis;
option cccv6.primary-dhcp <ipv6 address of the server>
When I start the DHCP server with this config, it does not complain about
the config.
But when a device requests option 2171, the server does not include the
option 2171 in the vendor specific options.
What am I doing wrong?
Best Regards,
