Different card is the same as DUID

[yon]

my an client server has two NIC,but it is Different card is the same as DUID.

if I want to setup Static ipv6 address for that two NIC,How I do ?

[databeestje]

correct, the duid file is generated the 1st time the dhcp6 client launches. It identifies the host, not the network interface.

This is normal.

If you just want to assign a static IPv6 address the duid is irrelevant.

well.., then why DHCPv6: Edit static mapping show ?
DUID Identifier
Enter a DUID Identifier in the following format:
"DUID-LLT - ETH – TIME --- ---- address ----"
"xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"

How I do input it?  I can input MAC address like ipv4 ?
