Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands
system mtu
The upper limit of the system routing MTU value is based on the switch or switch stack configuration
and refers to either the currently applied system MTU or the system jumbo MTU value.
If you enter a value that is outside the allowed range for the specific type of interface, the value is not
accepted.
Examples This example shows how to set the maximum jumbo packet size for Gigabit Ethernet ports to 6000 bytes:
Switch(config)# system mtu jumbo 6000
Switch(config)# exit
Switch# reload
You can verify your setting by entering the show system mtu privileged EXEC command.

ports of Catalyst 3750 members.
2. The system routing MTU value is the applied value, not the configured value.
