Information
Only the software-based trigger for retrieving and calculating the snapshots of the
statistical counters of the buffer space is supported. Collection of snapshots of
buffer statistical counters based on hardware threshold settings is not supported,
which can be used to specify the type of hardware threshold and the threshold
profile templates.

service-class buffer shared-threshold-weight
Create a service class and associate the threshold weight of the shared buffer with each of the queues
per port in the egress direction. A global buffer pool that is a shared buffer pool accessed by multiple
queues when the minimum guaranteed buffers for the queue are consumed can be configured on the
S6000 and Z9000 platforms.
