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 space 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 space configured for all queues cannot exceed the total fixed-area space. Otherwise, the configuration fails.
Examples
# Configure queue 0 to use 20% fixed-area space of cell resources in the egress buffer.
