3.2.3 Configuring the MTU of an Ethernet interface
The MTU is measured in bytes. The MTU range of Ethernet interfaces depends on the
physical devices. By default, the MTU is 1500 bytes.

NOTE
• After you change the MTU by using the mtu command on an interface, you need to restart the
interface to validate the newly configured value. To restart the interface, run the shutdown and undo
shutdown commands in succession, or run the restart command in the interface view.
• If subinterfaces exist, the shutdown and the undo shutdown commands must be run at an interval
of at least 15 seconds.
Configuring the IPv4 MTU

Step 1 Run:
system-view
