I am trying to utilize an old Dell R710 server that used to be in our
ESX cluster. To replace an even older FreeBSD server I have been
running. Because it's pretty stupid to throw massively better system in
the recycle pile while keeping the slower system online.
The problem I have is that the new server has 10G Ethernet adapters
connected with Cisco Twinax Cables.
Adapters are Intel 8259EB 10Gigabit AF Dual Port Adapters
We have Cisco Twinax Cables connecting them to an Avaya VSP 7000 series
switch
However I have been unable to get the interfaces to show any status
other than no carrier. I have tried everything including building a
custom kernel without the if_ix device and compiling the latest version
from Intel and installing that.
I have done an up command on the interfaces, tried setting an IP, but
nothing changes the status. Am I missing something or is the FreeBSD
Driver just not compatible with these Twinax Cables? The cards of course
were used with these cables on VMWare?
Here is the output from some commands below, there maybe some errors I
can't copy and past from the remote kvm console, so I had to type this
from reading the screen. this is just the first of the 4 interfaces.
dmesg:
