Usage
Information
You must be in INTERFACE mode in order to configure an interface to dynamically acquire an IP address
from a DHCP server.
Use the no ip address dhcp in INTERFACE mode to:
● Release the IP address that was dynamically acquired from a DHCP server from the interface.
● Disable the DHCP client on the interface so it cannot acquire a dynamic IP address from a DHCP
server.
● Stop DHCP packet transactions on the interface.
To release the IP address dynamically acquired from a DHCP server and allow an interface to acquire a
new DHCP server-assigned address, enter the release dhcp interface type slot/port
command in EXEC Privilege mode. To acquire a new server-assigned IP address, enter the renew dhcp
interface type slot/port command in EXEC Privilege mode or the ip address dhcp
command in INTERFACE Configuration mode.
ip address dhcp relay information-option
Include the relay-information option (option 82) in DHCP packets sent by the client. Some DHCP servers can be configured to
allocate IP addresses based on option 82.
