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.
Syntax
[no] ipv6 enable
Default Setting
IPv6 is disabled
Command Mode
Interface Configuration (VLAN, craft)
Command Usage
• 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 “ipv6
address eui-64” on page 609). 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.
Example
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.
Console(config)#interface vlan 1
Console(config-if)#ipv6 enable
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enable.
Link-local address:
FE80::2E0:CFF:FE00:FD/64
Global unicast address(es):
2001:DB8:2222:7273::72/96, subnet is 2001:DB8:2222:7273::/96
Joined group address(es):
FF02::1:FF00:72
