Configuring burst
The burst function improves packet buffering and forwarding performance in the following scenarios:
•
Dense broadcast or multicast traffic and massive burst traffic are present.
•
High-speed traffic is forwarded over a low-speed link or traffic received from multiple interfaces
at the same speed is forwarded through an interface at the same speed.
By enabling the burst function on your device, you can improve the processing performance of the
device operating in these scenarios to reduce packet loss.
Make sure that you are fully aware of the impacts when enabling the burst function, because the
burst function may affect the QoS performance of your device.
Configuration prerequisites
Make sure that the burst function is necessary for addressing your problem.
Configuration procedure
To enable the burst function:
Step
1.
Enter system view.
2.
Enable the burst function.
Burst configuration example
Network requirements
In the customer network shown in
Ethernet interface. The server sends dense broadcast or multicast traffic to the hosts irregularly.
Each host connects to the switch through a 100 Mbps network adapter.
Configure the switch to process dense traffic from the server to guarantee that packets can reach the
hosts.
