We need to connect orin’s 10Gb(mgbe1_0\rj45) network with another storage device’s 10Gb network for big data transmission, so we need to set the mgbe1_0’s MTU to 9000 to achieve better performance.
However, we found that the MTU of mgbe1_0 cannot be set to 9000(default value 1466).

How can I set the MTU to 9000 of mgbe1_0 successful?

Dear @xiaolei.qin,
Does that mean sudo ifconfig mgbe1_0 mtu 9000 up is not working?

Hello @SivaRamaKrishnaNV ,
Yes, after I execute the set MTU command, it will fail to execute.
But I tried other methods that seemed to work:

sudo ifconfig mgbe1_0 down
sudo ifconfig mgbe1_0 mtu 9000 up

Thanks for your replay.

Dear @xiaolei.qin ,
I got the issue. You might have tried to update when port is active. You need to down the port first to update the MTU
