Huawei AR3200 Series - Optional) Configuring VLAN Damping

run the shutdown command and then the undo shutdown command, or run the restart
command in the interface view.
l If you change the MTU of an interface, you must use the mtu command to change the MTU
of the peer interface to the same value; otherwise, services may be interrupted.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif vlan-id
The VLANIF interface view is displayed.
Step 3 Run:
mtu mtu
The MTU of the VLANIF interface is set.
The MTU of a VLANIF interface ranges from 46 to 1500, in bytes. The default value is 1500.
NOTE
If the MTU is too small whereas the packet size is large, the packet will probably split into many fragments.
As a result, the packet may be discarded due to insufficient QoS queue length. To avoid this situation,
lengthen the QoS queue accordingly.
