FC to queue map can be defined, this allows user to assign the packets classified into a
particular FC to any one of the queues configured for the SAP.
Both unicast traffic and BUM traffic share a single queue per FC. In other words, unlike
service ingress policy, it is not possible to assign different queues for BUM traffic and
unicast traffic.
The queue parameters such as queue shaper rate (CIR/PIR), cbs and mbs, queue priority
and weight can be defined. The assigned priority and weight is used to determine the
priority and weight of the queue in both the CIR and PIR scheduling loop.
Allow configuration of WRED slopes (per queue) - high-slope and low-slope. Depending
on the queue mode and the profile assigned to the packet on SAP ingress classification,
one of the configured WRED slopes is used to evaluate if a buffer can be allocated to the
packet. In-profile packets use the high-slope and out-of-profile packets use the low-slope.
Supports Strict priority (SP) scheduling and Weighted-Fair Queuing (WFQ) scheduling
for SAP ingress queues. For more information about service ingress scheduling see the
Chapter , Schedulers on 7210 SAS-K, on page
