Parameters

egress: Specifies the egress buffer.

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 applies to all IRF member devices.

cell: Specifies cell resources.

queue-id: Specifies a queue by its ID in the range of 0 to 7.

ratio ratio: Specifies the fixed-area ratio in percentage. The value range for ratio is 1 to 100.

Usage guidelines

By default, all queues have an equal share of the fixed area. You can set the fixed-area ratio for a

queue. The other queues equally share the remaining part.

The fixed-area space for a queue cannot be used by other queues. Therefore, it is also called the

minimum guaranteed buffer for the queue. The sum of fixed-area ratio configured for all queues

cannot exceed the total fixed-area ratio. Otherwise, the configuration fails.

Inappropriate data buffer changes can cause system problems. Before manually changing data

buffer settings, make sure you understand its impact on your device. As a best practice, use the

burst-mode enable command if the system requires large buffer spaces.

Examples

# Set the fixed-area ratio to 20% of cell resources in the egress buffer for queue 0.

<Sysname> system-view

[Sysname] buffer egress cell queue 0 guaranteed ratio 20

buffer queue shared

Use buffer queue shared to set the maximum shared-area ratio for a queue.

Use undo buffer queue shared to delete the maximum shared-area ratio setting of a queue.

Syntax

buffer egress [ slot slot-number ] cell queue queue-id shared ratio ratio

undo buffer egress [ slot slot-number ] cell queue queue-id shared

Default

The maximum shared-area ratio for a queue is 33%.
