Hello.
I have a Super Micro server with Intel 10-Gigabit X540-AT2 ethernet
controller, which doesn't want to speak to Cisco Nexus Nexus5548 at
10GBit/s.
I've checked that cable is fine, I can use it to establish
server-to-server 10GB/s connection or cisco-to-cisco 10GB/s connection.
But cisco-to-server auto-negotiation happens only on 1GB/s.
I've tried to turn off en_1000fdx_cap and en_100fdx_cap, but it doesn't
help.
Can I somehow disable auto-negotiation and force adapter to use fixed
duplex and speed?
Something like
http://sysadminsjourney.com/content/2008/05/08/forcing-nic-speed-and-duplex-solaris-10/
doesn't work, and dladm doesn't allow me to set adv_100fdx_cap or
adv_1000fdx_cap to 0.
Now device properties look like this (tried to disable adv_autoneg_cap,
link just went down) :
