You can configure priority mappings on switches.
When packets are sent to the inbound or outbound interface of a device, the device determines the queues and priorities of packets according to 8021.p, DSCP or the IP precedence field. The S2750, S5700EI,S5700SI, and S5700LI switches support priority mappings for incoming packets. The S5700HI, S5710EI and S6700 series switches support priority mappings for incoming packets and outgoing packets.
