Jumbo frames are larger than standard Ethernet frames and can be used to boost network performance and throughput. To configure jumbo frames on a Linux system, you will need to follow these steps:
Verify that jumbo frames are supported: Make sure that your network hardware and switches support jumbo frames. You will also need to ensure that your Linux kernel has the CONFIG_NET_JUMBO_FRAMES option enabled. You can check the kernel configuration by running the cat /boot/config-$(uname -r) command.
Set the MTU size: Set the maximum transmission unit (MTU) size to the desired jumbo frame size using the ip command. For example, to set the MTU size to 9000 bytes (the maximum jumbo frame size), you can use the following command:
sudo ip link set mtu 9000 dev eth0
Replace eth0 with the name of the network interface that you want to configure. You will need to repeat this step for each network interface that you want to use with jumbo frames.
ip command to verify that the MTU size has been set correctly. For example, to check the MTU size for the eth0 interface, you can use the following command:ip link show eth0 | grep mtu
