This example shows how to configure the Layer 2 Ethernet port 3/1 with the default MTU size (1500):
switch# configure terminal
switch(config)# interface ethernet 3/1
switch(config-if)# switchport
switch(config-if)# mtu 1500
switch(config-if)#
Configuring the System Jumbo MTU Size
You can configure the system jumbo MTU size, which can be used to specify the MTU size for Layer 2
interfaces. You can specify an even number between 1500 and 9216. If you do not configure the system
jumbo MTU size, it defaults to 9216 bytes.

Configuring the Basic Interface Parameters
Purpose
Specifies to use Layer 2 or Layer 3.
For a Layer 2 interface, specifies either the
default MTU size (1500) or the system
jumbo MTU size (9216 unless you have
changed the system jumbo MTU size).
For a Layer 3 interface, specifies any even
number between 576 and 9216.
Displays the interface status, which
includes the MTU size.
Exits the interface mode.
(Optional) Copies the running
configuration to the startup configuration.
