Interface Configuration
Common Interface Configuring Commands
This section describes common interface commands which support IP address and helper syntaxes in the C4/c CMTS.
Configure an IP Address on the CAM Interface
The following command is accepted only for provisioned CAM slot/port combinations in the system. This command assigns
an IP address to the CAM interface and determines its DHCP policy:
configure interface cable-mac <mac> ip address <ipAddr> <mask> [secondary] [dhcp-giaddr]
Secondary IP addresses become candidates for the dhcp-giaddr field if and only if the keywords secondary and dhcp-giaddr
are both used.
The command in the example below assigns an IP address of 10.10.1.1 to the specified CAM interface. It enables DHCP
policy for this interface — secondary IP addresses are candidates for the dhcp-giaddr field:
configure interface cable-mac 1 ip address 10.10.1.1 255.255.255.0 secondary dhcp-giaddr
Configure the Helper (DHCP) Addresses
The following command defines the cable-helper information for a CAM slot/port. This command assumes the default
route table:
configure interface cable-mac <mac> cable helper-address <DHCP Server Ip Addr>
[cable-modem|host|any]
If no host type is specified, this command defaults to a value of any.
Configure DHCP Relay Agent Mode for a Cable-mac
The DHCP Relay Agent needs to be enabled for each cable-mac as follows:
config interface cable-mac <mac> cable dhcp-giaddr {primary | policy}
