queue-id: Specifies a queue by its ID in the range of 0 to 7.
ratio ratio: Specifies the maximum shared-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 shared area. You can set the shared-area ratio for
a queue. The unconfigured queues use the default setting. The shared-area ratio for each queue is
finally determined by the chip based on your configuration and the number of packets to be received
and sent.
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
# Configure queue 0 to use up to 10% shared-area space of cell resources in the egress buffer.
<Sysname> system-view
[Sysname] buffer egress cell queue 0 shared ratio 10
buffer total-shared
Use buffer total-shared to set the total shared-area ratio.
Use undo buffer total-shared to delete the total shared-area ratio setting.
Syntax
buffer egress [ slot slot-number ] cell total-shared ratio ratio
undo buffer egress [ slot slot-number ] cell total-shared
Default
The total shared-area ratio is 91%.

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.
ratio ratio: Specifies the ratio of the shared area, in percentage. The value range for ratio is 1 to 100.
Usage guidelines
After you set the total shared-area ratio, the remaining buffer space is automatically assigned to the
fixed area.
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
# Configure the shared area to use 50% space of cell resources in the egress buffer.
