Configuring Interface Encapsulation on Physical Interfaces
Setting the Protocol MTU on page 65
When you initially configure an interface, the protocol maximum transmission unit (MTU)
is calculated automatically. If you subsequently change the media MTU, the protocol
MTU on existing address families automatically changes.
For a list of default protocol MTU values, see
To modify the MTU for a particular protocol family, include the
mtu bytes;
You can include this statement at the following hierarchy levels:
