Note:
1. 4-priority scheduler for Gen-3 adapter card or platform.
3.5.3.1 Network Ingress 4-Priority Scheduling
The adapter cards listed in Table 12 under “4-Priority” can receive network ingress
traffic. One or more ports on the card is configured for PPP/MLPPP for this purpose.
The implementation of network ingress scheduling on the cards listed in Table 12
under “4-Priority” is very similar to the scheduling mechanisms used for adapter
cards that are configured for access ingress traffic. That is, 4-priority scheduling is
used (queue-type scheduling combined with profiled scheduling).
