Configures
Maximum transmission unit (MTU)
Default
Depends on media type (defaults for some common media are listed in
Table 15-10, under the ip mtu
command)
Description
This command allows you to modify the MTU for any interface. The default MTU depends on the media you are using (FDDI, Ethernet, etc.); for example, Ethernet has an MTU of 1500.
Performance considerations may lead you to modify this value; a smaller MTU might give better performance on a lossy or noisy line.
Example
