Mellanox 100G CX456A not autoconfiguring link local ipv6 address


I am using CX456A Mellanox 100G cards. I have two cards. in one card Link local address is configuring after boot automatically.

But on other card it is not happening. Any configuration parameter need to set ?

enp9s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

inet6 fe80::e61d:2dff:fea3:aca4 prefixlen 64 scopeid 0x20

ether e4:1d:2d:a3:ac:a4 txqueuelen 1000 (Ethernet)

RX packets 0 bytes 0 (0.0 B)



all is well that ends well…:-)

Thanks for your information. this is problem with our X86 machine. On another x86 machine. the issue resolved

I’m not sure I fully understand your problem description.

Is it that one adapter is showing up and exposed properly after reboot, while the other one is not?

what do you mean by “boot automatically” is it a self reboot or am initiated reboot?

what is the Operating Sytem? have you installed proper driver & adapter firmware properly?

try to be more specific and provide full issue-scenario and relevant technical information.
