IPv6 on your Switch
This section describes the switch’s support for IPv6, and how to configure IPv6 on the
switch.
Enabling IPv6
The switch’s implementation of IPv6 is disabled by default. To enable IPv6 forwarding, use
the
ipv6 forwarding command on page 27.7 .
To display information about IPv6 settings, use the show ipv6 interface brief command
on page 27.22 .
Because the switch implements IPv6 as a dual stack, implementing IPv6 does not affect
IPv4 functionality.
IPv6 Stateless Address Autoconfiguration (SLAAC)
The switch’s implementation of IPv6 supports SLAAC on an interface. To enable IPv6
SLAAC on an interface, use the
ipv6 address autoconfig command on page 27.4 . SLAAC
automatically applies the MAC address of the interface to an IPv6 address for the interface
specified.
ipv6 address autoconfig enables automatic configuration of IPv6 addresses on an
interface using stateless autoconfiguration, and enables IPv6 processing on an interface.
IPv6 EUI-64 Addressing
The switch’s implementation of IPv6 supports EUI-64 addressing. EUI-64 applies an IPv6
address that is based on the MAC address of the interface. The EUI-64 identifiers from the
MAC address are used as the least significant 64 bits of a unicast address.
To enable IPv6 EUI-64, use the ipv6 address command on page 27.2 specifying the
optional eui64 parameter for an interface.
When configuring SLAAC you must ensure that you set the prefix length to 64 bits on the
switch that is advertising the RAs used for address configuration via SLAAC.
Prefix information received in an RA (Router Advertisement) will not be applied to form an
IPv6 address via SLAAC unless the prefix length is 64. Since the EUI is 64 bits long, the IPv6
prefix of the advertising device must also be 64 bits. This prefix length setting and
behavior is in accordance with RFC 4864, section 5.5.3.
