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

display buffer usage

Use display buffer usage to display buffer usage.

Syntax

display buffer usage [ slot slot-number ]

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

slot slot-number: Specifies an IRF member device by its member ID (slot number). If you do not specify an IRF member device, this command displays buffer usage for all IRF member devices.

Examples
