Layer 3 Ethernet interface and subinterface
commands
mtu
Use mtu to set the MTU for an Ethernet interface or subinterface.
Use undo mtu to restore the default.
Syntax
mtu size
undo mtu
Default
The MTU of a GigabitEthernet interface or subinterface is 1500 bytes and of a Ten-GigabitEthernet
interface is 9216 bytes.
Views
Layer 3 Ethernet interface view, Layer 3 Ethernet subinterface view
Default command level
2: System level
Parameters
size: Sets the maximum transmission unit (MTU) in bytes. The value range for a GigabitEthernet interface
or subinterface is 46 to 1500, and the value range for a Ten-GigabitEthernet interface is 46 to 9216.
Examples
# Set the MTU to 1430 bytes for the Layer 3 Ethernet interface GigabitEthernet 0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] mtu 1430
# Set the MTU to 1400 bytes for the Layer 3 Ethernet subinterface GigabitEthernet 0/1.1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1.1
[Sysname-GigabitEthernet0/1.1] mtu 1400
promiscuous
Use promiscuous to configure a Layer 3 Ethernet interface to operate in promiscuous mode.
Use undo promiscuous to cancel the promiscuous operating mode.
Syntax
promiscuous
undo promiscuous
Default
A Layer 3 Ethernet interface does not operate in promiscuous mode.
