4. Check the current status of the NIC
Mii-tool "Usually used in the computer room after the network card connection check", cable connection, and the current transmission speed (1000BASET-FD)
Instance
[Email protected]:~# Mii-tool

Siocgmiiphy on ' eth1 ' Failed:resource temporarily unavailable
Siocgmiiphy on ' eth2 ' Failed:resource temporarily unavailable
Siocgmiiphy on ' Eth3 ' Failed:resource temporarily unavailable

5. Check the NIC driver
Ethtool

The above is a personal point of summary and understanding, the level is not high, the level of writing is very bad, please greatly forgive me.
Can exchange learning together.
