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.
After the Burst feature is enabled, the following data buffer settings are changed:
Fixed-area space for a queue.
Shared-area space for a queue.
Total shared-area space.
You can display the data buffer setting changes by using the display buffer command.
Disabling the Burst feature might cause the PFC function to be on longer in effect or to operate incorrectly. For information about PFC configuration commands, see Layer 2—LAN Switching Command Reference.
