Usage guidelines
The Burst feature is especially useful for reducing packet losses under the following circumstances:
· 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.
Examples
# Enable the Burst feature.
<Sysname> system-view
[Sysname] burst-mode enable
