ipv6 address
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 in 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.

If a link local address has not yet been assigned to this interface, this
◆
command will dynamically generate a global unicast address (if a global
prefix is included in received router advertisements) and a link local
address for the interface. (The link-local address is 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.
When DHCPv6 is restarted, the switch may attempt to acquire an IP
◆
address prefix through stateful address autoconfiguration. If the router
advertisements have the "other stateful configuration" flag set, the
switch may also attempt to acquire other non-address configuration
information (such as a default gateway) when DHCPv6 is restarted.

This example assigns a dynamic global unicast address of
2001:DB8:2222:7272:2E0:CFF:FE00:FD to the switch.
