Interface Configuration mode
User Guidelines
This command enables IPv6 on an interface (if it was disabled) and causes
the switch to perform IPv6 stateless address auto-configuration to discover
prefixes on the link and then to add the eui-64 based addresses to the
interface.
Stateless auto configuration is applied only when IPv6 Forwarding is disabled.
When IPv6 forwarding is changed from disabled to enabled, and stateless
auto configuration is enabled the switch stops stateless auto configuration
and removes all stateless auto configured ipv6 addresses from all interfaces.
When IPv6 forwarding is changed from enabled to disabled and stateless auto
configuration is enabled the switch resumes stateless auto configuration.
Using the no ipv6 address autoconfig command to disable stateless auto
configuration and to remove all stateless auto configured IPv6 addresses from
an interface.
Example
The following example assigns the IPv6 address automatically:
console(config)# interface vlan 100
console(config-if)# ipv6 address autoconfig
console(config-if)#
exit
ipv6 address eui-64
Use the ipv6 address eui-64 command in Interface Configuration mode to
configure an IPv6 address for an interface and enables IPv6 processing on the
interface using an EUI-64 interface ID in the low order 64 bits of the address.
To remove the address from the interface, use the no form of this command.
Syntax
ipv6 address ipv6-prefix / prefix-length eui-64

ipv6-prefix / prefix-length eui-64]
