Figure 99 QoS Mode
QoS Burst
Options: Enable/Disable
Default: Disable
Function: When multiple source ports forward traffic to one destination port or a high-speed
port forwards traffic to a low-speed port, the traffic received by the port exceeds the capacity
of the port. As a result, excess data will be lost. After the function is enabled, the cache
capacity of the port is increased, so that excess data will not be lost.
Caution:

When a high-speed port forwards traffic to a low-speed port or multiple ports forward traffic to
one port with little or no traffic transmitted among these ports, QoS Burst is recommended to
reduce data losses. When traffic is being transmitted among multiple ports, the function may
affect forwarding capability. In this case, you are recommended to disable QoS Burst.

When QoS Burst is enabled, traffic control does not work. Therefore, use the function with
caution.
