Related Commands
ipv6 address eui-64 (603)
ipv6 address autoconfig (602)
show ipv6 interface (608)
ip address (590)
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.
Syntax
[no] ipv6 address autoconfig
Default Setting
No IPv6 addresses are defined
Command Mode
Interface Configuration (VLAN)
Command Usage
• 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.
