ARAMETERS

These parameters are displayed:

◆

Relay Mode

- Enables or disables the DHCP relay function.

(Default: Disabled)

◆

Relay Server

- IP address of DHCP server to be used by the switch's

DHCP relay agent.

◆

Relay Information Mode

- Enables or disables the DHCP Relay Option

82 support. Note that Relay Mode must also be enabled for Relay

Information Mode to take effect. (Default: Disabled)

◆

Relay Information Policy

- Sets the DHCP relay policy for DHCP

client packets that include Option 82 information.

■

Replace

- Overwrites the DHCP client packet information with the

switch's relay information. (This is the default.)

■

Keep

- Retains the client's DHCP information.

■

Drop

- Drops the packet when it receives a DHCP message that

already contains relay information.

NTERFACE

To configure DHCP Relay:

Click Advanced Configuration, Security, Network, DHCP, Relay.

Enable the DHCP relay function, specify the DHCP server’s IP address,
enable Option 82 information mode, and set the policy by which to

handle relay information found in client packets.

Click Save.
