ip-link:tldr:13015

This command is used to set the Maximum Transmission Unit (MTU) value for a specific network interface.

Here's a breakdown of the command:

• ip is the command-line utility for managing network interfaces in Linux.
• link specifies that we want to configure a network link (interface).
• set indicates that we want to modify the settings of the specified network interface.
• ${ethN} is a placeholder for the network interface name. You would replace ${ethN} with the actual name of the network interface you want to modify (e.g., eth0, eth1).
• mtu is a parameter that specifies we want to change the MTU value.
• ${9000} is a placeholder for the desired MTU value. Here, it is set to 9000 bytes. You can replace ${9000} with any other value you prefer, depending on your network requirements.

Overall, this command sets the MTU value for a specified network interface, allowing you to adjust the maximum size of data packets that can be transmitted through that interface.
