cdxQosIfRateLimitShpGranularity The width in milliseconds of each element in shaping delay
queue, that is, the shaping granularity.
The shaping granularity is only applied to rate limit
algorithm: Token bucket algorithm with shaping. It controls
how accurately the algorithm quantizes the shaping delay for
a rate exceeded flow. If granularity is large, several shaping
delay values will all be quantized to the same element in the
queue resulting in less accurate rate shaping for the flows in
bits/sec. On the other hand, choosing too small granularity
causes more memory to be used for the shaper block, and also
can cost a bit more in runtime overhead.
If the rate limit algorithm is not Token bucket algorithm with
shaping, the value is always na(1) which is not applicable.
The enumerations for shaping granularity are:
• na(1): shaping granularity is not applied to the current
rate limit algorithm
• msec1(2): shaping granularity in 1 milliseconds
• msec2(3): shaping granularity in 2 milliseconds
• msec4(4): shaping granularity in 4 milliseconds
• msec8(5): shaping granularity in 8 milliseconds
• msec16(6): shaping granularity in 16 milliseconds
The downstream shaping granularity is configurable and the
default value is msec4(4). Whenever the downstream rate
limit algorithm is changed to Token bucket algorithm with
shaping from other rate limit algorithm, the value will be
reset to the default value.
The upstream shaping granularity is not configurable and it is
read-only value.
