Chapter 19 IP Configuration

19.5.3.1 DHCP Relay Agent Information

The switch can add information to client DHCP requests that it relays to a DHCP server. This helps provide authentication about the source of the requests. You can also specify additional information for the switch to add to the client DHCP requests that it relays to the DHCP server. Please refer to RFC 3046 for more details.

The DHCP relay agent information feature adds an Agent Information field to the option 82 field of the DHCP headers of client DHCP request frames that the switch relays to a DHCP server. The following lists the DHCP relay agent option 82 information that the switch sends to the DHCP server:

•Slot ID (1 byte)

•Port ID (1 byte)

•VLAN ID (2 bytes)

•System name (up to 32 bytes, this is optional)

Follow the steps below to set the switch as a DHCP server.
