You canleave the CircuitID object at the default (the system name andthe PII of the port or VC).CRAFT> set cmdhcp [1.4.1.0] function=dhcpforwardserveripaddr=204.20.20.30Set SuccessfulCRAFT> get cmdhcp [1.4.1.0]Group: cmDHCPTableInstance: [1.4.1.0]PII = 1.4.1.0RowStatus= ActiveIpAddress = 10.1.2.3NetMask = 255.255.255.255DefaultRoute = 204.20.20.10DNSServer = 204.20.20.30Function= DHCPForwardServerIPAddr = 0.0.0.0CircuitID= CMTN-1.4.1.0The CE150 performs the following functions when it receives aDHCP request:1. For a CMCP CPE, the CE150 modifies the DHCPrequest by inserting the CircuitID from thecmDHCPTable into the Relay Agent Information andClient Identifier fields in the DHCP request message.For a non-CMCP CPE or a host on the premise LAN, theCE150 modifies the DHCP request by inserting theCircuitID only into the Relay Agent Information field.&KDSWHU$GYDQFHG&RQILJXUDWLRQ
