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.
