User Guidelines
• An IP address cannot be configured for a range of interfaces (range context).
Example
The following example configures VLAN 1 with the IP address 131.108.1.27 and subnet mask
255.255.255.0.
ip address dhcp
The ip address dhcp Interface Configuration mode command acquires an IP address on an interface
from the Dynamic Host Configuration Protocol (DHCP) server. Use the no form of this command to
deconfigure any acquired address.
The no ip address dhcp command deconfigures any IP address that was acquired, thus sending a
DHCPRELEASE message.
