Data Sheet
Granularity when Delay bound is used: QOSC08: 128 bytes, QOSC07: 256 bytes. QOSC06: 512 bytes. Granularity
when WFQ is used: QOSC08: 512 bytes, QOSC07: 512 bytes, QOSC06: 512 bytes.
13.7.27
Accessed by serial interface (R/W):
C - QOSC09 – BYTE_C31 (CPU Address 520)
B - QOSC10 – BYTE_C32 (CPU Address 521)
A - QOSC11 – BYTE_C33 (CPU Address 522)
QOSC09 through QOSC011 represents one set of values A-C for a 10/100 port when using the Weighted Random
Early Drop (WRED) scheme.
Granularity when Delay bound is used: QOSC11: 128 bytes, QOSC10: 256 bytes, QOSC09: 512 bytes.
Granularity when WFQ is used: QOSC11: 512 bytes, QOSC10: 512 bytes, QOSC09: 512 bytes
13.7.28
Accessed by serial interface and I²C (R/W):
F - QOSC12 – BYTE_C2_G1 (I²C Address h0C7, CPU Address 523)
E - QOSC13 – BYTE_C3_G1 (I²C Address h0C8, CPU Address 524)
D - QOSC14 – BYTE_C4_G1 (I²C Address h0C9, CPU Address 525)
C -QOSC15 – BYTE_C5_G1 (I²C Address h0CA, CPU Address 526)
B - QOSC16 – BYTE_C6_G1 (I²C Address h0CB, CPU Address 527)
A - QOSC17 – BYTE_C7_G1 (I²C Address h0CC, CPU Address 528)
QOSC12 through QOSC17 represent the values A-F for Gigabit port 1. They are per-queue byte thresholds for
random early drop. QOSC17 represents A, and QOSC12 represents F.
Granularity when Delay bound is used: QOSC17 and QOSC16: 256 bytes, QOSC15 and QOSC14: 512 bytes,
QOSC13 and QOSC12: 1024 bytes.
Granularity when WFQ is used: QOSC17 to QOSC12: 1024 bytes
