Priority Mapping

Context

After priority mapping is configured, the switch determines the queues that received packets enter and output priorities of the received packets based on packet priorities or the default priority of the interface. By doing this, the switch provides differentiated services.

Only the S2720-EI, S5720I-SI, S5720-LI, S5720S-LI, S5735S-H, and S5736-S support this function.
