Parameters
ipv6-address/prefix-length: Specifies an IPv6 address and IPv6 prefix length. The ipv6-address and
prefix-length arguments jointly specify the prefix of an EUI-64 IPv6 address. The value range for the
prefix-length argument is 1 to 64.
Usage guidelines
An EUI-64 IPv6 address is generated based on the specified prefix and the automatically generated
interface ID. To display the EUI-64 IPv6 address, use the display ipv6 interface command.
The prefix length of an EUI-64 IPv6 address cannot be greater than 64.
Examples
# Configure an EUI-64 IPv6 address for VLAN-interface 100. The prefix of the address is the same
as that of 2001::1/64, and the interface ID is generated based on the MAC address of the device.
Method 1:
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 address 2001::1/64 eui-64
Method 2:

Parameters
ipv6-address: Specifies an IPv6 link-local address. The first 10 bits of an address must be
1111111010 (binary). The first group of hexadecimals in the address must be FE80 to FEBF.
Usage guidelines
Manual assignment takes precedence over automatic generation.
If you use automatic generation, and then use manual assignment, the manually assigned link-local
address overwrites the one that is automatically generated.
If you use manual assignment and then use automatic generation, both of the following occur:
