| + | To increase the number of units the port can request from the shared pool, increase the SoftMax threshold using the command qos queue-softmax-multiplier <100-1200>. The highest value is 1200 and will increase by a multiple of 12 the ability of a single port queue to absorb micro-bursts. This command will uplift the port queue thresholds so that the port queue can consume additional buffer units from the shared pool. The shared pool is a limited resource, as it is physical memory, and hence not all ports can consume from the shared pool all units they need to handle all micro-bursts. The buffer sharing itself assumes that the micro-bursts will not happen on all ports on the switch at the same time. If micro-bursts happen in random moments, the shared buffer will be able to dedicate additional buffer units to absorb them. By using DTS in this way, the UADP ASIC makes the use of the PBC buffer very efficient. |
