ip mtu

Sets the MTU.

Synopsis ip mtu size

no ip mtu

Operands size Specifies the size of the maximum transmission unit (MTU) of an interface.

Defaults MTU size is 1500 bytes.

Command Modes Interface subtype configuration mode

Description Use this command to specify the MTU on a specific interface.

Usage Guidelines The entire fabric acts like a single switch. Therefore, MTU is applicable only on edge ports and not

on an ISL.

The allowed MTU size is from 576 to 9018 bytes.

Enter no ip mtu to reset the MTU size to the default.

Examples To set the MTU size to 2000 bytes on a specific 10-gigabit Ethernet interface:

switch(config)# interface tengigabitethernet 178/0/9

switch(conf-if-te-178/0/9)# ip mtu 2000
