The following table describes the labels in this screen.

27.3 DHCP Relay

Configure DHCP relay on the Switch if the DHCP clients and the DHCP server are not in the
same broadcast domain. During the initial IP address leasing, the Switch helps to relay
network information (such as the IP address and subnet mask) between a DHCP client and a
DHCP server. Once the DHCP client obtains an IP address and can connect to the network,
network information renewal is done between the DHCP client and the DHCP server without
the help of the Switch.
The Switch can be configured as a global DHCP relay. This means that the Switch forwards all
DHCP requests from all domains to the same DHCP server. You can also configure the Switch
to relay DHCP information based on the VLAN membership of the DHCP clients.

27.3.1 DHCP Relay Agent Information

The Switch can add information about the source of client DHCP requests that it relays to a
DHCP server by adding

Relay Agent Information

. This helps provide authentication about

the source of the requests. The DHCP server can then provide an IP address based on this
information. Please refer to RFC 3046 for more details.
The DHCP

Relay Agent Information

feature adds an Agent Information field to the

Option

82

field. The

Option 82

field is in the DHCP headers of client DHCP request frames that the

Switch relays to a DHCP server.

Relay Agent Information

can include the

System Name

of the Switch if you select this

option. You can change the

System Name

in

Basic Settings

>

General Setup

.

The following describes the DHCP relay

information that the Switch sends to the DHCP

server:

LABEL

DESCRIPTION

Relay Mode

This field displays:
•

None

- if the Switch is not configured as a DHCP relay agent.

•

Global

- if the Switch is configured as a DHCP relay agent only.

•

VLAN

- followed by a VLAN ID if it is configured as a relay agent for specific

VLAN(s).

DESCRIPTION

Slot ID

(1 byte) This value is always 0 for stand-alone switches.

Port ID

(1 byte) This is the port that the DHCP client is connected to.
