accepted. 

Once the switch reloads, you can verify your settings by entering the show system mtu privileged EXEC 
command.

This example shows how to set the maximum packet size for a Gigabit Ethernet port to 1800 bytes:

Switch(config)# system mtu jumbo 1800

Switch(config)# exit

Switch# reload

This example shows the response when you try to set Gigabit Ethernet interfaces to an out-of-range 
number:

Switch(config)# system mtu jumbo 25000
