Add DHCP Interface Page
The
Add DHCP Interface Page contains the following field:
• Interface — Selects the interface to define DHCP Relay. The possible field
values are:
- Ports — Defines the DHCP Relay on the selected port.
- LAGs — Defines the DHCP Relay on the selected LAG.
- VLAN — Defines the DHCP Relay on the selected VLAN.
STEP 3 Select the Interface on which to define a DHCP Relay.
STEP 4 Click Apply. A DHCP Relay Interface is defined, and the device is updated.
Defining DHCP Relay (Layer 3)
The DHCP Server Page enables users to establish a DHCP configuration with
multiple DHCP servers to ensure redundancy. IP Addresses are controlled and
distributed one-by-one to avoid overloading the device.
The DHCP servers act as a DHCP relay if the parameter is not equal to 0.0.0.0.
DHCP requests are relayed only if their SEC field is greater or equal to the
threshold value. This allows local DHCP Servers to respond first.
To define the DHCP Relay (Layer 3) configuration:
