Implications of SIP and SPA Slot Mapping
Interfaces and sessions that have an egress QoS have their schedules and queues present in the QFP-3rd-Gen
ASIC that services the particular slot. Since there is a limitation of 29000 schedules and 116000 queues per
QFP-3rd-Gen ASIC, multiple QFP-3rd-Gen ASICs should be targeted by placing the SIP and SPA in the
correct order, in order to achieve full system scalability for schedules and queues.
For example, A 5xGE SPA supports more than 32000 point-to-point protocol (PPP) sessions depending on
the ESP. However, if QoS is applied to these sessions, the QFP-3rd-Gen ASIC that supports the SIP and SPA
slot can support only 29000 schedules, and these sessions share the 116000 queue limit. To support PPP
