Predefined user roles network-admin Parameters egress: Specifies the egress buffer. slot slot-number: Specifies a member device by its number in an IRF fabric. Without this option, the command applies to all member devices. cell: Specifies cell resources. queue-id: Specifies a queue by its number in the range of 0 to 7. ratio ratio: Specifies the fixed-area space ratio, in percentage. Usage guidelines When you manually configure the fixed-area ratios for queues, the sum of ratios of the queues cannot be greater than or equal to 100%, and queues 5, 6, and 7 must have available fixed area space. 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 have an equal share of 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 ratios configured for queues cannot be greater than or equal to 100%, and queues 5, 6, and 7 must have available fixed area space.

Parameters
egress
: Specifies the egress buffer.
slot
slot-number
: Specifies a member device by its number in an IRF fabric. Without this option, the
command applies to all member devices.
cell
: Specifies cell resources.
queue-id
: Specifies a queue by its number in the range of 0 to 7.
ratio
ratio
: Specifies the fixed-area space ratio, in percentage.
Usage guidelines
When you manually configure the fixed-area ratios for queues, the sum of ratios of the queues cannot be
greater than or equal to 100%, and queues 5, 6, and 7 must have available fixed area space.
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 have an equal share of 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 ratios configured for queues cannot be greater
than or equal to 100%, and queues 5, 6, and 7 must have available fixed area space.
Examples
# Configure queue 0 to use 15% fixed-area space of cell resources in the egress buffer of IRF member
device 2.
<Sysname> system-view

buffer queue shared
Use
buffer queue shared
to set the maximum shared-area ratio for a queue.
Use
undo buffer queue shared
to restore the default setting.
