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 10/100 ports; the system jumbo MTU refers to Gigabit ports.
Examples
This is an example of output from the
show system mtu
command:
Switch#
show system mtu
System MTU size is 1500 bytes
System Jumbo MTU size is 5000 bytes
System Alternate MTU size is 2000 bytes
Routing MTU size is 1500 bytes
This is an example of output when you have defined an alternate MTU size, but not reloaded the switch:
Switch#
show system mtu
System MTU size is 1500 bytes
System Jumbo MTU size is 5000 bytes
System Alternate MTU size is 1500 bytes
On next reload, System Alternate MTU will be 2000 bytes
