MTU (Maximum Transmission Unit) is a networking term that refers to the largest possible size of a data packet that can be transmitted over a network. MTU is measured in bytes and is typically set to the smallest common denominator of all the links on a network path. In Windows, you can check the MTU size of a network interface by using the following steps:
- Click on the Start menu and type “cmd” in the search bar.
- Right-click on the Command Prompt icon and select “Run as administrator”.
- Type the following command and press Enter:“`netsh interface ipv4 show subinterfaces“`
The MTU size is important because it can affect the performance of network applications. If the MTU size is too small, packets may be fragmented, which can lead to performance degradation. If the MTU size is too large, packets may be dropped, which can also lead to performance degradation.
