Use the "ipv6" command to display and configure the IPv6 settings.
View Setting
msh> ipv6
IPv6 stateless address
msh> ipv6 stateless {on|off}
If "on" is selected, IPv6 requests information required for maintaining stateful connection to the router for as long as the machine power is turned on. This setting allows information from the router to be obtained constantly, and periodically refreshes the effective period of the stateless address.
