Nếu các đường truyền của bạn được sử dụng 1000Mb/s nhưng port mạng chỉ nhận 100Mb/s các bạn chạy lệnh sau để up full port.
1. Kiểm tra port mạng đang có speed bao nhiêu (vd: port eno1)
ethtool eno1
Thông số trả về

2. Set port mạng speed lên speed 1000
ethtool -s eth0 speed 1000 duplex full autoneg on
Sau đó kiểm tra lại port thêm lần nữa
ethtool eno1
