DHCP Overview

DHCP is generally used between clients and servers for the purpose of

assigning IP addresses, gateways, and other network settings such as DNS and

SNTP server information.

DHCP Snooping is a security feature that monitors DHCP messages between

a DHCP client and DHCP server. It filters harmful DHCP messages and

builds a bindings database of (MAC address, IP address, VLAN ID, port)

tuples that are specified as authorized. DHCP snooping can be enabled

globally and on specific VLANs. For information about DHCP Snooping, see

"Snooping and Inspecting Traffic" on page 993.

Dell EMC Networking N-Series switches support a DHCP client for

obtaining the switch address from the network, an IPv4 DHCP server for

serving IPv4 addresses to DHCP clients in the network, layer-2 and layer-3

NOTE: The DHCP server is not available on the Dell EMC Networking N1500

Series switches.
