DHCP Relay

The DHCP Relay Page provides information for establishing a DHCP configuration with multiple
DHCP servers to ensure redundancy. IP Addresses are controlled and distributed one-by-one to avoid
overloading the device

opens:
The DHCP Relay Page contains the following fields:
• DHCP Relay— Enable or Disables DHCP on the device.
• DHCP Server — Adds a DHCP Server to the DHCP Relay Table. 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.
2. Click the Add button. The Add DHCP Server Page opens:
