ipv6 enable
This command enables IPv6 on an interface that has not been configured
with an explicit IPv6 address. Use the
no form to disable IPv6 on an
interface that has not been configured with an explicit IPv6 address.

◆
This command enables IPv6 on the current VLAN interface and
automatically generates a link-local unicast address. The address prefix
uses FE80, and the host portion of the address is generated by
converting the switch’s MAC address to modified EUI-64 format (see
page 1088 ). This address type makes the switch accessible over IPv6
for all devices attached to the same local subnet.
◆
If a duplicate address is detected on the local segment, this interface
will be disabled and a warning message displayed on the console.
◆
The no ipv6 enable command does not disable IPv6 for an interface
that has been explicitly configured with an IPv6 address.
E
XAMPLE
In this example, IPv6 is enabled on VLAN 1, and the link-local address
FE80::2E0:CFF:FE00:FD/64 is automatically generated by the switch.
