The 10Gb spec is autonegotiation only. You can limit the speeds a side will negotiate with, but there is no "turning it off" completely and nailing a speed as one could with older, slower ethernet protocols.
Have you verified that the Cisco switch is free and clear of any configuration which may impede natural autonegotiation? It could also be a cable issue; or even a card issue - since you have a -AT2 card, try the other socket as well as a verified working cat6a cabe (or cat6 if < 30 meters) to see if the situation is different. /dale > On Oct 26, 2016, at 5:23 AM, Alexander Pyhalov <[email protected]> wrote: > > 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) : > > # dladm show-linkprop ixgbe3 > LINK PROPERTY PERM VALUE DEFAULT POSSIBLE > ixgbe3 speed r- 0 0 -- > ixgbe3 autopush rw -- -- -- > ixgbe3 zone rw -- -- -- > ixgbe3 duplex r- unknown unknown half,full > ixgbe3 state r- down up up,down > ixgbe3 adv_autoneg_cap rw 0 1 1,0 > ixgbe3 mtu rw 1500 1500 1500-15500 > ixgbe3 flowctrl rw no no no,tx,rx,bi > ixgbe3 adv_100gfdx_cap r- -- 0 1,0 > ixgbe3 en_100gfdx_cap -- -- 0 1,0 > ixgbe3 adv_40gfdx_cap r- -- 0 1,0 > ixgbe3 en_40gfdx_cap -- -- 0 1,0 > ixgbe3 adv_10gfdx_cap r- 1 1 1,0 > ixgbe3 en_10gfdx_cap rw 1 1 1,0 > ixgbe3 adv_5000fdx_cap r- -- 0 1,0 > ixgbe3 en_5000fdx_cap -- -- 0 1,0 > ixgbe3 adv_2500fdx_cap r- -- 0 1,0 > ixgbe3 en_2500fdx_cap -- -- 0 1,0 > ixgbe3 adv_1000fdx_cap r- 1 1 1,0 > ixgbe3 en_1000fdx_cap rw 0 1 1,0 > ixgbe3 adv_1000hdx_cap r- -- 0 1,0 > ixgbe3 en_1000hdx_cap -- -- 0 1,0 > ixgbe3 adv_100fdx_cap r- 1 1 1,0 > LINK PROPERTY PERM VALUE DEFAULT POSSIBLE > ixgbe3 en_100fdx_cap rw 0 1 1,0 > ixgbe3 adv_100hdx_cap r- -- 0 1,0 > ixgbe3 en_100hdx_cap -- -- 0 1,0 > ixgbe3 adv_10fdx_cap r- -- 0 1,0 > ixgbe3 en_10fdx_cap -- -- 0 1,0 > ixgbe3 adv_10hdx_cap r- -- 0 1,0 > ixgbe3 en_10hdx_cap -- -- 0 1,0 > ixgbe3 maxbw rw -- -- -- > ixgbe3 cpus rw -- -- -- > ixgbe3 cpus-effective r- 0-4,7-19 -- -- > ixgbe3 pool rw -- -- -- > ixgbe3 pool-effective r- -- -- -- > ixgbe3 priority rw high high low,medium,high > ixgbe3 tagmode rw vlanonly vlanonly normal,vlanonly > ixgbe3 forward rw 1 1 1,0 > ixgbe3 default_tag rw 1 1 -- > ixgbe3 learn_limit rw 1000 1000 -- > ixgbe3 learn_decay rw 200 200 -- > ixgbe3 stp rw 1 1 1,0 > ixgbe3 stp_priority rw 128 128 -- > ixgbe3 stp_cost rw auto auto -- > ixgbe3 stp_edge rw 1 1 1,0 > ixgbe3 stp_p2p rw auto auto true,false,auto > LINK PROPERTY PERM VALUE DEFAULT POSSIBLE > ixgbe3 stp_mcheck rw 0 0 1,0 > ixgbe3 protection rw -- -- mac-nospoof, > restricted, > ip-nospoof, > dhcp-nospoof > ixgbe3 allowed-ips rw -- -- -- > ixgbe3 allowed-dhcp-cids rw -- -- -- > ixgbe3 rxrings rw -- -- -- > ixgbe3 rxrings-effective r- 8 -- -- > ixgbe3 txrings rw -- -- sw,hw,<1-7> > ixgbe3 txrings-effective r- 8 -- -- > ixgbe3 txrings-available r- 7 -- -- > ixgbe3 rxrings-available r- 0 -- -- > ixgbe3 rxhwclnt-available r- 0 -- -- > ixgbe3 txhwclnt-available r- 7 -- -- > > -- > С уважением, > Александр Пыхалов, > программист отдела телекоммуникационной инфраструктуры > управления информационно-коммуникационной инфраструктуры ЮФУ > ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
