QOSC56~57 - Class 6 Shaper Control Port G1
Accessed by CPU and serial interface
QOSC56[5:0] – TOKEN_RATE_G1 (CPU Address 54f).
Programs the average rate for gigabit port 1. When equal to 0, shaper is disable. Granularity is 1.
QOSC57[7:0] – TOKEN_LIMIT_G1 (CPU Address 550).
Programs the maximum counter for gigabit port 1. Granularity is 16 bytes.
Shaper is implemented to control the peak and average rate for outgoing traffic with priority 6 (queue 6). Shaper is
limited to gigabit ports and queue P6 when it is in strict priority. QOSC41 programs the peak rate for gigabit port 1.
See Programming QoS Registers Application Note for more information.
12.3.6.37
QOSC58~59 - Class 6 Shaper Control Port G2
Accessed by CPU and serial interface
QOSC58[5:0] – TOKEN_RATE_G2 (CPU Address 551).
Programs de average rate for gigabit port 2. When equal to 0, shaper is disable. Granularity is 1.
QOSC59[7:0] – TOKEN_LIMIT_G2 (CPU Address 552).
Programs the maximum counter for gigabit port 2. Granularity is 16 bytes.
Shaper is implemented to control the peak and average rate for outgoing traffic with priority 6 (queue 6). Shaper is
limited to gigabit ports and queue P6 when it is in strict priority. QOSC49 programs the peak rate for gigabit port 2.
