Default scheduling configuration for the SX-FI48GPP module

The default scheduling configuration for Weighted Round Robin (WRR), Strict Priority (SP), and mixed
WRR and SP mode for the eight QoS priority (qosp) queues mapped to the four hardware queues is
described in the following table.

Default configuration for 8 to 4 queues for the SX-FI48GPP module

Note that the above table includes values for default, non-jumbo mode WRR. The hardware queues
are calculated using default qosp values from the Default values for scheduling type for stacking and
stand-alone systems (for FCX and ICX 6450 platforms)
table as follows:

Front end queue 3= 75% (qosp7) + 7% (qosp6) = 82%

Front end queue 2 = 3% (qosp4) + 3% (qosp5) = 6%

Front end queue 1 = 3% (qosp2) + 3% (qosp3) = 6%

Front end queue 0 = 3% (qosp0) + 3% (qosp1) = 6%

The hardware queues for mixed WRR and SP mode are calculated as follows:

Front end queue 3 is Strict Priority as default values for qosp7 and qosp6 are SP

Front end queue 2 = 25% (qosp4) + 15% (qosp5) = 40%

Front end queue 1 = 15% (qosp2) + 15% (qosp3) = 30%

Front end queue 0 = 15% (qosp0) + 15% (qosp1) = 30%
