In Huawei switches, traffic suppression (also known as storm control) can be configured in the VLAN view or interface view. This function controls the traffic rate of certain types of packets to prevent broadcast storms or excessive flooding.

In the VLAN view, suppression is typically supported for:

✅ Broadcast packets

✅ Unknown multicast packets

✅ Unknown unicast packets

❌ Known unicast packets are generally not subject to suppression because they are correctly forwarded based on MAC address learning.

✅ Official Reference from Huawei:

" The traffic suppression function on a switch limits the rate of broadcast, unknown multicast, and unknown unicast traffic. This function can be configured in the VLAN view to control traffic types by bit rate. "
