Usage Information
When you enter the release dhcp command, although the IP address that was dynamically-acquired from a
DHCP server is released from an interface, the ability to acquire a new DHCP server-assigned address remains in
the running conguration for the interface. To acquire a new IP address, enter either the renew dhcp command
at the EXEC privilege level or the
ip address dhcp command at the interface conguration level.
