Usage Guidelines
If you have used the system mtu or system mtu jumbo global configuration command to change the
MTU setting, the new setting does not take effect until you reset the switch.
The system MTU refers to ports operating at 10/100 Mbps; the system jumbo MTU refers to Gigabit
ports; the system routing MTU refers to routed ports.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.

Switch# show system mtu
