146 CHAPTER 2: CUDA 12000 BASE SYSTEM COMMANDS
Arguments
{enable | disable} Specifies one of the following values:
■ enable – Enables DHCP on the current cable interface.
■ disable – Disables DHCP on the current cable interface.
cpe-gateway <gi-address> Configures the IP gateway for CPE devices connected to
the current interface. You must enter one of the IP
addresses (interfaces) that you have added to the current
physical interface.
The relay agent on the card places this address in the
giaddr field of the DHCP packet before forwarding the
requests to the DHCP server. The server then checks the
LDAP database to see if you have configured subnets for
this network, and then selects the network address based
on the subnet definition.
Note that you must define subnets for the address that
you specify in this field; if the DHCP server cannot find a
corresponding subnet for this network, it will not assign IP
addresses.
cm-gateway <gi-address> Configures the IP gateway for cable modems connected to
the current interface. You must enter one of the IP
addresses (interfaces) that you have added to the current
physical interface.
The relay agent on the card places this address in the
giaddr field of the DHCP packet before forwarding the
requests to the DHCP server. The server then checks the
LDAP database to see if you have configured subnets for
this network, and then selects the network address based
on the subnet definition.
Note that you must define subnets for the address that
you specify in this field; if the DHCP server cannot find a
corresponding subnet for this network, it will not assign
the requesting device an IP address.
add-agent-options
{enable | disable}
Add additional DHCP relay agent functionality. Enable
this parameter if you have specified two different IP
gateways – one for modems and a different one for CPE
devices.
drop-mismatch
{enable | disable}
Used to authenticate DHCP client-to -server
communication. If enabled, configures the system to drop
DHCP server replies that do not contain an Agent ID
suboption that identifies origination from the DHCP server.
