Setting the Protocol MTU
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 “Configuring the Media MTU” on page 53.
To modify the MTU for a particular protocol family, include the mtu statement:
mtu bytes;
You can include this statement at the following hierarchy levels:
