How can I force the NIC to full duplex?

ethtool -s eth0 speed 100 duplex full autoneg off

Note that the switch you're connected to will also have to be forced to full
duplex -- if one side is set to autonegotiate, the fallback is half duplex.

Chloe] how can I put it in boot time? ls it in rc.local ?




and change the mtu

ifconfig


chloe] Do you know whether there is any network issue if we don't change MTU as same as our provider? eg: our upstream provider router is using mtu 1600 but our end is 1500.

where the file should I set it in boot time?

depends...

chloe] can you give me example?

have you tried to force 10G full duplex?

Wait, hold on. What hardware do you have and what are you trying to do?

chloe] I will use the fedora as router. the NIC is "myrim 10G network card"


Thank you for your help
