		• In this example, the low-latency queue is restricted to
	Example:	250 kbps to protect low-priority traffic from starvation
	RP/0/RP0/CPU0:router(config-pmap-c)# police cir	and to release bandwidth.
	250 exceed-action drop
Step 5
	priority	Specifies priority to a class of traffic belonging to a policy
		map.
	Example:
	RP/0/RP0/CPU0:router(config-pmap-c)# priority
