PurposeCommand or Action

(Optional) Change the MTU size for all interfaces on the

system mtu bytes

Example:

Switch(config)# system mtu 2500

Step 2

The range is 1500 to 1998 bytes; the default is 1500 bytes.

(Optional) Changes the MTU size for all Gigabit Ethernet

interfaces on the switch or the switch stack.

system mtu jumbo bytes

Example:

Switch(config)# system mtu jumbo 7500

Step 3

The range is 1500 to 9198 bytes; the default is 1500 bytes.

Step 5

Reloads the operating system.reload

Example:

Switch# reload

Step 6

Verifies your settings.show system mtu

Example:

Switch# show system mtu

Step 7

Configuration Examples for System MTU

This example shows how to set the maximum packet size for a Gigabit Ethernet port to 7500 bytes:

Switch(config)# system mtu jumbo 7500

Switch(config)# exit

Switch# reload

If you enter a value that is outside the allowed range for the specific type of interface, the value is not accepted.

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
