HAPTER 12: CONFIGURING DHCP RELAY
Match Criteria DHCP Policies allow matching on several
parameters in the DHCP packet, including:
■ Agent-Options – Determines whether the
DHCP request is from a cable modem, CPE
device, or MTA device.
■ Cable Modem MAC Address – Allows you
to match on the cable modem MAC
address contained in the request.
■ Interface – Enables you to match on the
specific interface on which the DHCP offer
was received.
■ MAC Address – Allows you to match on
the source MAC address of the cable
modem. You can also wildcard any or all
octets of the MAC address.
Policy Action Specifies the action that you want the system
to take upon finding a matching DHCP
request. You can configure the interface to do
the following:
■ Permit the packet to be forwarded to up to
32 DHCP servers
■ Deny (drop) the packet without forwarding
it
Forward-Internal Specifies that the current cable interface
forwards DHCP requests internally (meaning,
to a DHCP server on the local Cuda 12000).
Optionally, you can specify the disable
keyword to disable internal forwarding.
