Defining DHCP Relay Interfaces

This page enables configuring the port, LAG, or VLAN interfaces that support the DHCP Relay functions. For the DHCP Relay to function, it also must be activated globally in the Properties page.

To define the DHCP Relay interfaces:

  1. Click IP Configuration > DHCP Relay (Layer 2 or Layer 3) > DHCP Relay Interfaces. The DHCP Relay Interfaces page opens.
  2. This page displays the interfaces where DHCP Relay is defined, and their IP addresses. In Layer 3, port, LAG, or VLANs are offered; in Layer 2 only VLANs are offered.

  3. To add an interface, click Add. The Add DHCP Interface (Layer 2) page opens.
  4. Enter the Interface value.
    • If the switch is in Layer 2 mode, select the VLAN that is to be DHCP Relay enabled.
    • If the switch is in Layer 3 mode, select whether the interface is for a port, VLAN, or LAG.
  5. Click Apply. A DHCP Relay interface is defined, and the Running Configuration file is updated.
