QOSC36~39 - Classes WFQ Credit Set 3
Accessed by CPU and serial interface
W0 - QOSC36[5:0] – CREDIT_C30 (CPU Address 53b)
W1 - QOSC37[5:0] – CREDIT_C31 (CPU Address 53c)
W2 - QOSC38[5:0] – CREDIT_C32 (CPU Address 53d)
W3 - QOSC39[5:0] – CREDIT_C33 (CPU Address 53e)
QOSC39 through QOSC36 represents one set of WFQ parameters for a 10/100 port. There are four such sets of
values. The granularity of the numbers is 1 and their sum must be 64. QOSC39 corresponds to W0 and QOSC36
corresponds to W0.
QOSC36[7:6]: Priority service type for the ports select this parameter set. Option 1 to option 4.
QOSC37[7]: Priority service allow flow control for the ports select this parameter set.
QOSC37[6]: Flow control pause best effort traffic only

[7:6]: Priority service type. Option 1 to 4.
W1 - QOSC41[5:0] – CREDIT_C1_G1 (CPU Address 540)
[7]: Priority service allow flow control for the ports select this parameter set.
[6]: Flow control pause best effort traffic only
W2 - QOSC42[5:0] – CREDIT_C2_G1 (CPU Address 541)
W3 - QOSC43[5:0] – CREDIT_C3_G1 (CPU Address 542)
W4 - QOSC44[5:0] – CREDIT_C4_G1 (CPU Address 543)
W5 - QOSC45[5:0] – CREDIT_C5_G1 (CPU Address 544)
W6 - QOSC46[5:0] – CREDIT_C6_G1 (CPU Address 545)
W7 - QOSC47[5:0] – CREDIT_C7_G1 (CPU Address 546)
QOSC40 through QOSC47 represents the set of WFQ parameters for Gigabit port 24. The granularity of the
numbers is 1 and their sum must be 64. QOSC47 corresponds to W7 and QOSC40 corresponds to W0.
12.3.6.35

[7:6]: Priority service type. Option 1 to 4
W1 - QOSC49[5:0] – CREDIT_C1_G2(CPU Address 548)
[7]: Priority service allow flow control for the ports select this parameter set.
[6]: Flow control pause best effort traffic only
W2 - QOSC50[5:0] – CREDIT_C2_G2(CPU Address 549)
W3 - QOSC51[5:0] – CREDIT_C3_G2(CPU Address 54a)
W4 - QOSC52[5:0] – CREDIT_C4_G2(CPU Address 54b)
