made with an address prefix of FE80 and a host portion based the switch’s MAC
address in modified EUI-64 format.)

If a duplicate address is detected, a warning message is sent to the console.
Example
This example specifies a full IPv6 address and prefix length.

autoconfig
This command enables stateless autoconfiguration of IPv6 addresses on an
interface and enables IPv6 on the interface. The network portion of the address is
based on prefixes received in IPv6 router advertisement messages; the host portion
is based on the modified EUI-64 form of the interface identifier (i.e., the switch’s
MAC address). Use the
no
form to remove the address generated by this command.
