Cuda 12000 IP Access Switch CLI Reference Guide
dhcp-relay 145
dhcp-relay
Configures DHCP parameters on the current cable (CMTS) interface. DHCP is used within a
DOCSIS-compliant network to allocate IP addresses and configure modems with other IP
parameters. DOCSIS modules function as DHCP relay agents and forward DHCP requests from
modems and connected CPE devices to a DHCP server. Use this command to specify the DHCP
server that you want the cable interface to use, as well as configure other DHCP relay
parameters, such as gateways for cable modems, CPE devices, and MTAs.
Use the no form of the command to remove a gateway or server.
