I have a server in a data center, which has an Ethernet NIC card with Fibre support. I have a 1Gbps connection and my ISP asked me to make sure the settings on my device are as follows:
Full Duplex, 1000meg and NO Auto Negotiation
However, I just realized that my NIC only supports 10000T. Here is the output from ethtool eth2
Settings for eth2:
Supported ports: [ FIBRE ]
Supported link modes: 10000baseT/Full
Supports auto-negotiation: No
Advertised link modes: 10000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: Unknown!
Duplex: Unknown! (255)
Port: FIBRE
PHYAD: 0
Transceiver: external
Auto-negotiation: off
Supports Wake-on: d
Wake-on: d
Current message level: 0x00000014 (20)
link ifdown
Link detected: no
I haven't yet connected the cable to the NIC. Do you think there will be a "speed mismatch", as the ISP end is configured at 1000T and my NIC supports only 10000T?
PS: the make/model of NIC is: Mellanox ConnectX-3 En.
