CableLabs Option 122

isc dhcpd should work with it

class "xxxxxxxxxx" {
match if option agent.remote-id = x:xx:xx:xx:xx:xx;
}

pool {
range x.x.x.x x.x.x.x;
allow members of "xxxxxxxxxxxx";
}

Cisco Broadband Access Center works correct with option 122.

BACC supports both PacketCable DHCP option 122 (as specified in RFC 3495 and 3594) and the deprecated PacketCable DHCP option 177. BACC does not ignore DHCP requests when it cannot populate option 122 and/or 177 content. Whatever option 122/177 content is available is populated and the decision to ignore the option is left to the EMTA.

But it is far not freeeware :)

Though low performance issue, ISC DHCP server, but it's free!!!

You can try this:

## Define MTA's class
class "MTA-CPE"
{
match if substring (option vendor-class-identifier, 0, 5) = "pktc1";
}

option space TSP;
option TSP.prov-server code 3 = string;
option TSP.kerberos code 6 = string;
option TSP-encap code 122 = encapsulate TSP;
option TSP.prov-server 00:09:70:72:6f:76:69:73:69:6f:6e:06:73:65:72:76:65:72:06:64:6f:6d:61:69:6e:04:6e:61:6d:65:00;
# provision.server.domain.name in hex
# 00+9(length)+provision+6+server+6+domain+4+name+00
option TSP.kerberos 05:42:41:53:49:43:01:31:00;
# BASIC.1 No Auth.

hi, i've been trying to do the same and everywhere says the i have to do it just like that, but it doesn't work. this is my dhcpd.conf:

ddns-update-style none;
ignore client-updates;

option space docsis-mta;
option docsis-mta.dhcp-server-1 code 1 = ip-address;
option docsis-mta.dhcp-server-2 code 2 = ip-address;
option docsis-mta.provision-server code 3 = { integer 8, string };
option docsis-mta.as-req-as-rep-1 code 4 = { integer 32, integer 32, integer 32 };
option docsis-mta.as-req-as-rep-2 code 5 = { integer 32, integer 32, integer 32 };
option docsis-mta.krb-realm-name code 6 = string;
option docsis-mta.tgs-util code 7 = boolean;
option docsis-mta.timer code 8 = integer 8;
option docsis-mta-pkt code 122 = encapsulate docsis-mta;

i'm using sbv5120 and bsr1000 (both from motorola). what i'm doing wrong? perhaps the service flows on the cmts? my brain is on fire :twisted: . thanks

I have a good option122(sub 1,2,3,6) tool for windows(write by myself),if you have interesting,please give me mail.

I'm using docsis server . It is possible to run sbv5120E on this server?

Did you figure this out?

Frank

yes, i (stupidily) forgot to pass the option 'hostname' to the mtas, so just add:
use-host-decl-names on;
at the beginning of the configuration, and:
group {
filename "cm-mta";
option dhcp.bootfile-name "cm-mta";
host 0016b5db5c18 { hardware ethernet 00:16:b5:db:5c:18; }
...
}
after the other groups. i' should try to prepare something cleaner (with ldap would be nice) but i don't have much time right now.

Glad to hear...getting my DHCP configuration correct the first time (I was complete newbie) took me a small week or two on and off. It takes just one setting to be off to not work at all.

The encapsulation of the DHCP 122 options was what troubled me the most. The ISC-DHCP listserv helped me out there.

Hello everyone,

I have been experimenting with trying to boot an Aris voip cable modem using docsis server, but so far I have not been able to make it work. The MTA I have been using requires DHCP option 122 suboption 1. I have added this information to the config_opts table, but the modem still will not boot. Using Ethereal to capture the transaction between the server, and modem I get:

Option: (122) CableLabs Client Configuration
Length: 4
Value: 0C24AF09
subopt 12: unknown/reserved:

No matter what the sub_option value is set to in the config_options table, ethereal always shows "suboption 12". This incorrect suboption value is undoubtedly causing the problem. Has anyone been able to get suboption 122 to work from docsis server?

We have built a basic php web interface to provision modems, and clients in docsis server. It is still a bit rough but it includes many features found in high end provisioning systems.

* Add, delete, and modify modem, and dhcp leases.
* Search by host Mac, modem Mac, ip addresses, or customer name
* Search Log tables
* Poll real time modem and host information via docsis diag, and isg tools.
* Reset Modems and hosts

If you would like a copy of the web interface let me know.

Thank for your help!

Hi,

read my thread here: http://docsis.org/node/486

I wrote a patch for docsis_server_35 and it works great.

regards,

Michael
