Scheduling Priority

J-series devices support per-unit scheduling that allows you to configure scheduler maps on each MLPPP or MLFR multilink bundle. You can also configure scheduler maps on constituent links, but you must maintain the same relative priority on the constituent links and on the multilink bundle.

Table 84 shows an example of correct and incorrect relative priorities on a multilink bundle and its constituent link. In this example, you have assigned a high priority to LFI packets and a low priority to data packets on the multilink bundle. To maintain the relative priority on the constituent links, you can assign a high priority to the LFI packets and a medium-high priority to the data packets, but you cannot assign a medium-high priority to LFI packets and a high priority to data packets.

Table 84: Relative Priorities on Multilink Bundles and Constituent Links

Multilink Bundle	Correct Constituent Link Priorities	Incorrect Constituent Link Priorities
LFI packets—High priority	LFI packets—High priority	LFI packet—Medium-high priority
Data packets—Low priority	Data packets—Medium-high priority	Data packets—High priority
