Configuring DHCP Server Port-Based Address Allocation
Command

Step 8 copy running-config startup-config
After enabling DHCP port-based address allocation on the switch, use the ip dhcp pool global
configuration command to preassign IP addresses and to associate them to clients. To restrict
assignments from the DHCP pool to preconfigured reservations, you can enter the reserved-only DHCP
pool configuration command. Unreserved addresses that are part of the network or on pool ranges are
not offered to the client, and other clients are not served by the pool. By entering this command, users
can configure a group of switches with DHCP pools that share a common IP subnet and that ignore
requests from clients of other switches.
Beginning in privileged EXEC mode follow these steps to preassign an IP address and to associate it to
a client identified by the interface name.

Chapter 22 Configuring DHCP Features and IP Source Guard
Purpose
Automatically generate a subscriber identifier based
on the short name of the interface.
A subscriber identifier configured on a specific
interface takes precedence over this command.
Specify the interface to be configured, and enter
interface configuration mode.
Configure the DHCP server to use the subscriber
identifier as the client identifier on all incoming
DHCP messages on the interface.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter DHCP pool configuration mode, and define the
name for the DHCP pool. The pool name can be a
symbolic string (such as Engineering) or an integer
(such as 0).
Specify the subnet network number and mask of the
DHCP address pool.
Reserve an IP address for a DHCP client identified by
the interface name.
string—can be an ASCII value or a hexadecimal
value.
(Optional) Use only reserved addresses in the DHCP
address pool. The default is to not restrict pool
addresses.
Return to privileged EXEC mode.
Verify DHCP pool configuration.
(Optional) Save your entries in the configuration file.
