Changing Interface State Using IP Command
Example 1: Bringing an Interface Up
To bring an interface up (activate it), you can use the `ip link` command with the `set` action. For example:
sudo ip link set eth0 up
This command brings the `eth0` interface up, enabling it to send and receive network traffic.
Example 2: Changing MTU (Maximum Transmission Unit)
To change the MTU (maximum transmission unit) of a network interface, you can use the `ip link` command with the `set` action and the `mtu` parameter. For instance:
sudo ip link set eth0 mtu 1500
This command sets the MTU of the `eth0` interface to `1500` bytes.
