QoS scheduler port configuration.
Committed information rate per iteration in cirType units
int32_t Qmss_QosSchedPortCfg::cirMax |
Max committed information rate credit in cirType units
Determines if committed information rate and peak information rate are specified in bytes or packets
Determines if congestion thresholds are specified in bytes or packets
Configuration for up to 5 groups
Number of logical groups in group
Output/egress queue associated with this port
uint16_t Qmss_QosSchedPortCfg::outThrotThresh |
Number of bytes or packets allowed in the output queue at any given time. Once this limit is reached, no further packets will be forwarded for this port on this tick. However, unused credits are stored the cir to be used on the next tick (up to cirMax) A value of 0 indicagtes no limit.
Determines if output throttle threshold is specified in bytes or packets
Number of bytes of wire overhead to account, beyond packet size in QM. This is often set to 24. This only affects credits deducted, not statistics. It also only has effect on credits configured as bytes, not packets. 0 is valid. This could be used to charge credits for preamble, start of frame, interframe gap, and CRC on ethernet. Note that both overheadBytes and removeBytes are applied to each packet if they are nonzero.
Number of bytes of accounting to remove from each packet in QM. This is often set to 24. This only affects credits deducted, not statistics. It also only has effect on credits configured as bytes, not packets. 0 is valid. This can be used to remove accounting for L1 or L2 headers in order to do L3 or L4 based shaping. Warning: if any packet enters QoS with a size less than this value, it will cause QoS to break. This is typically cuased by passing, unintentionally, a 0 value. Make sure the "C" register gets set for all packets before using this parameter. Note that both overheadBytes and removeBytes are applied to each packet if they are nonzero.
Determines if weighted round robin parameters are specified in bytes or packets
