Abstract

   This document defines a new sub-option for the CableLabs Client
   Configuration (CCC) Dynamic Host Configuration Protocol (DHCP) option
   code for conveying the network addresses of Key Distribution Center
   (KDC) servers.

1.  Introduction

   A CableLabs Client Configuration (CCC) Dynamic Host Configuration
   Protocol (DHCP) Option code providing the Key Distribution Center
   (KDC) server address will be needed for CableHome-compliant
   residential gateways configured to use Kerberos for authentication as
   the first step in establishing a secure SNMPv3 link between the
   Portal Service (PS) logical element [2,3] in residential gateways,
   and the SNMP entity in the cable operator's data network.

   The CCC DHCP option code will be used to address specific needs of
   CableLabs client devices during their configuration processes.  This
   document proposes a sub-option for the CCC DHCP option.
