The set l3-interface vlan-interface mtu command configures the maximum transmission unit (MTU) of a Layer 3 VLAN interface.
NOTE: The MTU value takes effect only on the outbound interface of the Layer 3 VLAN interface. |
Command Syntax
set l3-interface vlan-interface <interface-name> mtu <mtu-value>
Parameter
Parameter | Description |
interface <interface-name> | Specifies a Layer 3 VLAN interface. The value is a string. |
mtu <mtu-value> | Specifies the MTU of an interface. The value is an integer that ranges from 68 to 65535, in bytes. The default value is 1500 bytes. |
Usage Guidelines
An MTU value determines the maximum number of bytes in the IP layer packet that can be sent at a time. If the size of the data packets of the IP layer packet exceeds the MTU supported by a transit node or a receiver, the data packet is fragmented at the sender's IP layer, and the received fragments are reassembled at the receiver's IP layer.
Example
- Configure the MTU of the VLAN interface vlan10 as 2000.
