Default Value



This parameter specifies the DUID of the DUT’s CM DHCPv6 client. If specified, CDRouter’s DOCSIS DHCPv6 server will only respond to requests from the specific CM DHCPv6 client whose DUID matches this value; requests from other CM DHCPv6 clients will be ignored. When this parameter is set to “auto”, CDRouter’s DOCSIS DHCPv6 server will respond to any CM DHCPv6 client.

Note: Prior to CDRouter 13.9 CDRouter’s DOCSIS DHCPv6 server would only process DHCPv6 packets that matched the expected MAC address found in the docsisClientMac testvar. This testvar replaces that functionality by filtering on the DUID instead of MAC address.

This testvar was added in CDRouter 13.9
