Configure DHCP L2 Relay, DHCP Snooping, and Dynamic
ARP Inspection
This section describes how to configure the DHCP L2 Relay, DHCP snooping and Dynamic
ARP Inspection (DAI) features on the switch. DHCP snooping and DAI are Layer 2 security
features that examine traffic to help prevent accidental and malicious attacks on the switch or
network.
From the Services configuration menu, you can access pages that are described in the
following sections:
• DHCP L2 Relay on page 96
• DHCP Snooping on page 100
• Dynamic ARP Inspection on page 107
DHCP L2 Relay
DHCP relay agents eliminate the need to connect to a DHCP server on each physical
network. Relay agents populate the giaddr field and also append the Relay Agent Information
option to the DHCP messages. DHCP servers use this option for IP addresses and other
parameter assignment policies. These DHCP relay agents are typically IP routing-aware
devices and are referred to as Layer 3 relay agents. In some network configurations, a need
might exist for Layer 2 devices to append the Relay Agent Information option as they are
closer to the end hosts.
These Layer 2 devices typically operate only as bridges for the network and might not include
an IPv4 address on the network. Lacking a valid IPv4 source address, they cannot relay
packets directly to a DHCP server located on another network. These Layer 2 devices
append the Relay Agent Information option and broadcast the DHCP message.
