Enabling the Burst feature
The Burst feature enables the device to automatically allocate cell and packet resources. It is well
suited to the following scenarios:
•
Broadcast or multicast traffic is intensive, resulting in bursts of traffic.
•
Traffic enters a device from a high-speed interface and goes out of a low-speed interface.
•
Traffic enters a device from multiple same-rate interfaces and goes out of an interface with the
same rate.
To enable the Burst feature:
Step Command
Remarks
1.
Enter system view.
