DHCP overview
NOTE:
fter the DHCP client is enabled on an interface, the interface can dynamically obtain an IP address and
other configuration parameters from the DHCP server. This facilitates configuration and centralized
management. For more information about the DHCP client configuration, see "Interface management."
The Dynamic Host Configuration Protocol (DHCP) provides a framework to assign configuration
information to network devices.
DHCP uses the client/server model.

2. Creating an address pool for the DHCP server
î™» Creating a static address pool for the DHCP
server
î™» Creating a dynamic address pool for the DHCP
server
Required

IMPORTANT:
If the DHCP server and DHCP clients are on the same
subnet, make sure the address pool is on the same
network segment as the interface with the DHCP server
enabled; otherwise, the clients fail to obtain IP
addresses.
