Setting The Fixed-Area Ratio For A Queue; Applying Data Buffer Configuration; Displaying And Maintaining Data Buffers - HP FlexFabric 5700 series Configuration Manual

Setting the fixed-area ratio for a queue

By default, all queues have an equal share of the fixed area. This task allows you to change the fixed-area
ratio for a queue. The unconfigured queues equally share the remaining part.
The fixed-area space for a queue cannot be used by other queues. It is also called the minimum
guaranteed buffer.
When you set the fixed-area ratio for a queue, follow these restrictions and guidelines:
The sum of ratios configured for all queues cannot be greater than or equal to 100%. Queues 5, 6,
•
and 7 must have available fixed-area space.
After you configure the fixed-area ratios for some queues, the other queues each are assigned an
•
equal share of the remaining part of the fixed area. The display buffer queue command displays
the preceding whole number for each assignment result. Therefore, the sum of the ratios for all
queues might be less than 100%.
To set the fixed-area ratio for a queue:
Step
1. Enter system view.
2. Set the fixed-area ratio for a
queue.

Applying data buffer configuration

Perform this task to apply the data buffer configuration.
You cannot directly modify the applied configuration. To modify the configuration, you must cancel the
application, reconfigure data buffers, and reapply the configuration.
To apply data buffer configuration:
Step
1. Enter system view.
2. Apply data buffer configuration.

Displaying and maintaining data buffers

Execute display commands in any view.
Task
Display data buffer configuration.
Display data buffer usage.
Command
system-view
buffer egress [ slot slot-number ] cell
queue queue-id guaranteed ratio

The default setting is 12.5% for
each queue, but the default value
in the display buffer queue
command output is 13%.
