1st, you want to gather the interface MTU size but this requires you to get a list of the network interfaces
As you can see, the interface is the set defacto 1500bytes. We will adjust the interface by using the setMTU command with a new value.
NOTE: beadvise the OS will prompt you for the admin user account similar to the below
And that's how easy it is for changing a mtu setting. Most network interface allows you to decrease the MTU size from the 1500bytes defacto setting, but rarely it will allow you to increase the interface MTU size.
