5.16
dhcpclient set interfaceconfig autoip enabled|disabled
5.16.1 Syntax
dhcpclient set interfaceconfig {<name>|<number>} autoip
{enabled|disabled}
5.16.2 Description
This command enables/disables IP address auto-configuration (Auto-IP).
Auto-IP automatically configures an IP address when a DHCP client fails to
contact a DHCP server and cannot obtain a lease. An IP address on the
169.254 subnet is automatically created, and ARP requests are issued for the
suggested IP address. The address is abandoned if it already exists on the
network or if any other host on the network issues an ARP probe for that IP
address.
Once an IP address has been automatically configured, the DHCP client
continues to check whether or not it can contact a DHCP server. If the client
can contact a DHCP server and obtain a legitimate lease, the legitimate lease
will supersede the auto-configured IP address.
Note:
Even if you have enabled Auto-IP using this command, you will not be
able to use IP address auto-configuration if a DHCP server on the
same network does not allow it. See the
dhcpserver subnet add
option
command.
