mtu
Protocol-Specific Versions of the mtu Command
Changing the MTU value with the mtu interface configuration command can affect values for the
protocol-specific versions of the command (the ip mtu command, for example). If the value specified
with the ip mtu interface configuration command is the same as the value specified with the mtu
interface configuration command, and you change the value for the mtu interface configuration
command, the ip mtu value automatically matches the new mtu interface configuration command value.
However, changing the values for the ip mtu configuration commands has no effect on the value for the
mtu interface configuration command.
Examples The following example shows how to specify an MTU of 1000 bytes:
Router# configure terminal
Router(config)# vlan 20
Router(config-vlan)# name test20
Router(config-if)# mtu 1000
