Information About DHCP
DHCP Server
The DHCP server assigns IP addresses from specified address pools on a switch or router to DHCP clients
and manages them. If the DHCP server cannot give the DHCP client the requested configuration parameters
from its database, it forwards the request to one or more secondary DHCP servers defined by the network
administrator. The switch can act as a DHCP server.
DHCP Relay Agent
A DHCP relay agent is a Layer 3 device that forwards DHCP packets between clients and servers. Relay
agents forward requests and replies between clients and servers when they are not on the same physical subnet.
Relay agent forwarding is different from the normal Layer 2 forwarding, in which IP datagrams are switched
