PDF user manual for CopperEdge 150

When the netmodel is IP, the CPE or premise LAN host cannotobtain an IP address from the upstream DHCP server. TheCE150 simply drops the response it receives from the upstreamDHCP server.Cross-Connect, HDIA, VWAN, and CopperVPN NetmodelsWhen the netmodel is Cross-Connect, HDIA, VWAN, or Copper-VPN, you can configure the CE150 to act as a DHCP Server oras a DHCP Forwarding Agent for a port or VC.The CE150 as a DHCP ServerFor CMCP CPEs:• The CE150 responds to DHCP requests from CMCPCPEs for which there is an entry in the cmDHCPTable.• The CE150 generates a response based on theconfigured objects in the cmDHCPTable and sends theresponse back to the DSL port that it arrived on.For hosts on the premise LAN:• The CE150 forwards the DHCP requests to an upstreamDHCP router, which is responsible for sending therequest to the appropriate DHCP server.• The Forwarding function is described on page 85.For non-CMCP CPEs and hosts on the premise LAN:• The CE150 responds to DHCP requests from non-CMCPCPEs for which there is an entry in the cmDHCPTable.• However, the CE150 cannot differentiate between DHCPrequests coming from non-CMCP CPEs or hosts on thepremise LAN. It sends the same response for both.• Therefore, for non-CMCP CPEs, configure the CE150 asa Forwarding Agent instead of as a DHCP Server.
