DHCP Relay Settings

Use these parameters to define the DHCP client behavior for your test.

In WiFi Offload Gateway Node, the Second Relay Agent tab displays when you select Dual DHCP Relay Agent Nodes on the Emulator Configuration tab. The configuration on this tab corresponds to the Second DHCP Relay Agent Node on the Network Devices tab.

In AMF Node, gNB CU SA Nodal and SMF Node test cases, the Second Agent(v6) tab displays when you select both UE DHCPV4 IP Address and UE DHCPv6 IP Address on AMF Node Emulator Cnfg or gNB CU SA Nodal Test Configuration or SMF Node Emulator Cnfg. The configuration on this tab corresponds to the Second (v6) DHCP Relay Agent Node on the Network Devices tab.

IMPORTANT: Input correct DHCPv4 Server and DHCPv6 Sever information individually in the Relay Agent and Second Relay Agent tabs corresponding to the DHCP Relay Agent Node and Second DHCP Relay Agent Node.

Measurements collected for DHCP client processing are reported on the DHCP Relay Agent report tab.

You define the following parameters for your emulated DHCP Relay Agent in the DHCP Relay Agent Settings tab.

DHCP Server Address	The DHCP Server's IP address. Tcl parameter: DhcpServerAddr Tcl parameter: SecondDhcpServerAddr
Server Port	Enter the DHCP Server Port Tcl parameter: DhcpSrvPort Tcl parameter: SecondDhcpSrvPort
Circuit ID	An agent-local identifier of the circuit from which a DHCP client-to-server packet is received. You can use an Auto-Increment format in this field. Default is cid#. Tcl parameter: DhcpRelayCircuitId
Set GiAddr In DHCP Relay	In Wifi Offload Gateway Nodal test case, enter the Gi Address used in the DHCP Message forwarded by Relay Agent (The Relay Agent on Nodal). When selected, the DHCP Relay Agent’s address is populated, when not selected, the parameter in the DHCP message would be 0.0.0.0. (See RFC 2131). Tcl parameter: DhcpRelayAddGiAddrEn
Lease Query	Enable to Support DHCP Lease Query Message as defined in RFC 4388. Tcl parameter: DhcpRelayLeaseQueryEn Tcl parameter: SecondDhcpRelayLeaseQueryEn
Query Type	Three Lease Query Types are supported. Select one. IP Address - Supply an IP address in DHCP Lease Query Message. MAC Address - Supply a MAC address in DHCP Lease Query Message. Client Identifier - Supply a Client Identifier in DHCP Lease Query Message. Tcl parameter: DhcpRelayLeaseQueryType Tcl parameter: SecondDhcpRelayLeaseQueryType
SubOptions	Click to add rows to the table and enter the optional DHCP Relay Agent Sub Options (as described in RFC 3046). Enter a number of Type/Value suboption pairs. Click to display Tcl Parameter Information. The suboption entries are optional. If you enter a Type, you must enter a corresponding Value and vice versa. A byte counter displays the remaining bytes available as you add entries. Type: Enter any value from 2-255 Value: Enter any string value. A maximum of 255 bytes of suboptions are allowed.
