ip mtu
To set the IP maximum transmission unit (MTU) size of routed packets on all routed ports of the switch or
switch stack, use the
ip mtu
command in interface configuration mode. To restore the default IP MTU size,
use the
no
form of this command.
ip mtu bytes
no ip mtu bytes
Syntax Description
MTU size, in bytes. The range is from 68 up to the system MTU value (in bytes).
bytes
Command Default
The default IP MTU size for frames received and sent on all switch interfaces is 1500 bytes.
Command Modes
Interface configuration
Command History
Modification
Release
This command was introduced.
Cisco IOS XE 3.3SE
Usage Guidelines
The upper limit of the IP value is based on the switch or switch stack configuration and refers to the currently
applied system MTU value. For more information about setting the MTU sizes, see the
system mtu
global
configuration command.
To return to the default IP MTU setting, you can apply the
default ip mtu
command or the
no ip mtu
command
on the interface.
You can verify your setting by entering the
show ip interface interface-id
or
show interfaces interface-id
privileged EXEC command.
Examples
The following example sets the maximum IP packet size for VLAN 200 to 1000 bytes:
Device(config)#
interface vlan 200
Device(config-if)#
ip mtu 1000
The following example sets the maximum IP packet size for VLAN 200 to the default setting of 1500 bytes:
Device(config)#
interface vlan 200
Device(config-if)#
default ip mtu
This is an example of partial output from the
show ip interface interface-id
command. It displays the current
IP MTU setting for the interface.
Device#
show ip interface gigabitethernet4/0/1
GigabitEthernet4/0/1 is up, line protocol is up
Internet address is 18.0.0.1/24
Broadcast address is 255.255.255.255
