DHCP Relay
This chapter shows you how to set up DHCP relay.
17.1 DHCP Relay Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a DHCP server. You can configure the
AAM to relay client TCP/IP configuration requests to a DHCP server and the server's
responses back to the clients.
17.1.1 DHCP Relay Agent Information
The switch can add information to client TCP/IP configuration 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 TCP/IP configuration 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 TCP/IP configuration request frames that the switch relays
to a DHCP server. The following lists the DHCP relay agent option 82 information that the
switch may send 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).
