CDRouter Support


testvar version 12.8

Value Type


Default Value


This parameter specifies the IPv4 address that CDRouter will assign to the CM’s DHCP client on the WAN.

Note that CDRouter’s DOCSIS DHCP server will only respond to requests from CM DHCP clients, which are indentified by the presence of the string docsis in the Vendor Class Identifier option (option 60) of all received DHCP messages. All other clients will be serviced by CDRouter’s primary DHCP server.

CDRouter’s DOCSIS DHCP server can be configured to respond to a specific CM’s DHCP client by configuring the testvar docsisClientMac.

This testvar was added in CDRouter 10.3
