Specifying DHCP Servers 249
Specifying DHCP Servers
You must specify the DHCP server to which you want the cable interface to
forward DHCP Requests. The DHCP server is configured on a per interface
basis. You may add up to 32 DHCP servers.
If a DHCP server is not configured, then the DHCP server drops all DHCP
requests as it does not know where to forward them.
DHCP servers fall into two categories:
■External — DHCP servers that reside on systems other than the Cuda
12000 that has the cable interface that you are configuring. DHCP
messages are forwarded over the network to a remote, external DHCP
server.
■Internal — A FastFlow Broadband Provisioning Manager DHCP server
that resides on the same Cuda 12000 that has the cable interface you are
configuring (that is, the local Cuda 12000). DHCP requests are forwarded
internally to the DHCP server.

Specifying External DHCP Servers

To specify an external DHCP server, you configure the DHCP Relay Agent on
the cable interface to point to the IP address of a remote DHCP server. To do
so, perform the following tasks.
Example
The following example configures cable interface 1/1/1 to forward DHCP
messages to the DHCP server at address 201.1.13.1:
cli:172.16.19.10:root# interface 1/1/1
mode: interface:cable:csi(1/1/1)
cli:172.16.19.10:interface:cable:csi(1/1/1)# dhcp-policy
default permit 201.1.13.1
Task Command
1. Enter cable interface mode. interface cable <c/s/i>
2. Specify an external DHCP server. dhcp-policy default permit
<ip-address>
