Cable Modem and MTA Code 122

[Frank Bulk]

Daniel:

There's a lot more you need to add.  Here's my config:

option space cable-labs;
option cable-labs.tsp-primary-dhcp-server code 1 = ip-address;
option cable-labs.tsp-secondary-dhcp-server code 2 = ip-address;
option cable-labs.tsp-provisioning-server code 3 = { integer 8, string };
option cable-labs.tsp-as-backoff-retry code 4 = { unsigned integer 32,
unsigned integer 32, unsigned integer 32 };
option cable-labs.tsp-ap-backoff-retry code 5 = { unsigned integer 32,
unsigned integer 32, unsigned integer 32 };
option cable-labs.tsp-kerberos-realm-name code 6 = string;
option cable-labs.tsp-ticket-granting-server-utilization code 7 = boolean;
option cable-labs.tsp-provisioning-timer code 8 = unsigned integer 8;
option cable-labs-encapsulation code 122 = encapsulate cable-labs;

and in my subnet definition:

        option cable-labs.tsp-primary-dhcp-server 199.a.b.c;
        option cable-labs.tsp-secondary-dhcp-server 199.a.b.c;
        option cable-labs.tsp-kerberos-realm-name
05:42:41:53:49:43:01:31:00;
        option cable-labs.tsp-provisioning-server 0
"\007charlie\006mtcnet\003net\000";

The realm name, just in case your super-secret cereal box decoder doesn't
work, its BASIC.1.  Here's a website that helps encode the regular text, you
just have to use the proper encoding (decompose the realm by its levels, in
this case, "BASIC" and "1", and then prefix that section with string length,
which is why you see '5' and '1', and then close it with a '0'.  For
example, secure.acme.net would be 06 73 65 63 75 72 65 04 61 63 6D 65 03 6E
65 74 00

Subject: Cable Modem and MTA Code 122

I use the Scientific Atlanta DPC2203 Cable modem with MTA . I tried to
use the following configuration and it didn't solve:

Under your global options
 option voip122 code 122 = string;

under your subnet options
 option voip122 01:04:0a:00:00:02;

Somebody can help me?

Thanks

Daniel
