Configuring DHCP Service DHCP L2 Relay Configuration Circuit ID Customization Circuit ID Remote ID Customization Remote ID 2) Click Apply. Enable or disable Circuit ID Customization. Enable it if you want to manually configure the circuit ID. Otherwise, the switch uses the default one when inserting Option 82 to DHCP packets. The default circuit ID is a 4-byte value which consists of 2-byte VLAN ID and 2-byte Port ID. The VLAN ID indicates which VLAN the DHCP client belongs to, and the Port ID indicates which port the DHCP client is connected to. For example, if the DHCP client is connected to port 1/0/1 in VLAN 2, this field is 00:02:00:01 in hexadecimal. Enter the customized circuit ID with up to 64 characters. The circuit ID configurations of the switch and the DHCP server should be compatible with each other. Enable or disable Remote ID Customization. Enable it if you want to manually configure the remote ID. Otherwise, the switch uses its own MAC address as the remote ID. Enter the customized remote ID with up to 64 characters. The remote ID configurations of the switch and the DHCP server should be compatible with each other. 4.2 Using the CLI 4.2.1 Enabling DHCP L2 Relay Follow these steps to enable DHCP L2 Relay: Step 1 Step 2 Step 3 Step 5 Step 6 Step 7 configure Enter Global Configuration Mode. ip dhcp l2relay Enable DHCP L2 Relay. ip dhcp l2relay vlan vlan-list Enable DHCP L2 Relay for specified VLANs. vlan-list: Specify the vlan to be enabled with DHCP L2 relay. show ip dhcp l2relay Verify the configuration of DHCP Relay. end Return to Privileged EXEC Mode. copy running-config startup-config Save the settings in the configuration file.
