Layer 3 Ethernet interface configuration commands
mtu
Syntax
mtu size
undo mtu
View
Layer 3 Ethernet interface view
Default level
2: System level
Parameters
size: Sets the maximum transmission unit (MTU) in bytes, which ranges from 46 to 1560.
Description
Use mtu to set the MTU for a Layer 3 Ethernet interface.
Use undo mtu to restore the default.
By default, the MTU of a Layer 3 Ethernet interface is 1500 bytes.
Examples
# Set the MTU to 1430 bytes for the Layer 3 Ethernet interface Ethernet 1/0/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet 1/0/1] mtu 1430
