Ipv6 Address Eui-64 - HP E4510-48G Command Reference Manual

aggregatable global unicast address configured, the interface still has a link-local address. If the
interface has no IPv6 site-local address or aggregatable global unicast address configured, it will
have no link-local address.
Manual assignment takes precedence over automatic generation. That is, if you first adopt
automatic generation and then manual assignment, the manually assigned link-local address will
overwrite the automatically generated one. If you first adopt manual assignment and then
automatic generation, the automatically generated link-local address will not take effect and the
link-local address of an interface is still the manually assigned one. If you delete the manually
assigned address, the automatically generated link-local address is validated. For manually
assignment of an IPv6 link-local address, refer to the ipv6 address link-local command.
Examples
# Configure VLAN-interface 100 to automatically generate a link-local address.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 address auto link-local

Default Level
2: System level
Parameters
ipv6-address/prefix-length: IPv6 address and IPv6 prefix. The ipv6-address and prefix-length
arguments jointly specify the prefix of an IPv6 address in the EUI-64 format.
Description
Use the ipv6 address eui-64 command to configure a site-local address or global unicast address in
the EUI-64 format for an interface.
Use the undo ipv6 address eui-64 command to remove the configured site-local address or global
unicast address in the EUI-64 format for the interface.
By default, no site-local or global unicast address in the EUI-64 format is configured for an interface.
An EUI-64 IPv6 address is generated based on the specified prefix and the MAC address of the local
device and can be displayed by using the display ipv6 interface command.
Note that you cannot specify the prefix length of an IPv6 address in the EUI-64 format to be greater
than 64.
