Set up X99 on Ubuntu and optimize its speed to reach 1Gbps.
Set up X99 on Ubuntu and optimize its speed to reach 1Gbps.
You have four systems connected via a D-Link switch. Two x99 switches are set to 100Mb/s, and one MSI Z270 SLI and a Supermicro X10DRX are running at 1Gbps. The cables you're using are CAT 6. On Ubuntu 16.04.6 the lights stay orange during boot, which might not be related to the OS. If you want the x99 switches to operate at 1Gbps, check the cable type or configuration settings.
Reversing the cable connections will change the link speeds accordingly. The 10/100 link will transition to 10/100/1000, and the 10/100/1000 link will drop to 10/100. Try a newer Ubuntu release like 18.04.3 or 18.04.4 to see if the interface stabilizes.
I'm dealing with issue 16 because of the size of vast.ai. They need it. I'll attempt to change the cables and use a Cat 7 connection. The drivers from Intel's site didn't resolve the problem, though they mention support for up to 1 gigabit per second. However, at 100 meters this is causing issues. $ sudo lshw -class network * Network details: Ethernet interface product: Ethernet Connection (2) Vendor: Intel Physical ID: 19 logical name: eno1 version: 05 serial: 9c:5c:8e:4f:58:5f size: 100Mbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz features: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation config: autonegotiation=on broadcast=yes driver=e1000e driverversion=3.2.6-k capacity: 1Gbit/s link: yes multicast=yes port: twisted pair speed: 100Mbit/s resources: irq:61 memory:f5200000-f521ffff memory:f5222000-f5222fff ioport:f000 size: 32 * Network description: Ethernet interface product: I210 Gigabit Network Connection vendor: Intel Physical ID: 0 logical name: enp16s0 version: 03 serial: 9c:5c:8e:4f:58:60 capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi msix pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation config: autonegotiation=on broadcast=yes driver=igb driverversion=5.3.0-k firmware=3.25, 0x800005cf latency=0 link: no multicast=yes port: twisted pair
I've swapped in the new cat 6 cables and connected them to a Dlink DES-1210-28P switch. I also tried using my Dlink DIR -825ACG1 router, which has 1Gbps ports too. Both devices have GPS ports, but I'm puzzled why the two 1Gbps connections aren't working at full speed.
The DGS-1210 supports gigabit speeds, though you mentioned using a DES-1210—a 100Mbps device with a few 1Gbps links for uplink.
