Configuring Traffic Prioritization

QoS Classification

The EDS supports inspection of layer 3 TOS and/or layer 2 QoS tag information to determine how to classify traffic packets. (NOTE: The user interface for the EDS-408A shows 8 ports.)

Queuing Mechanism

	Setting	Description	Factory Default
		The EDS-408A/405A has 4 priority queues. In the
		weight fair scheme, an 8, 4, 2, 1 weighting is applied
	Weighted Fair	to the four priorities. This approach prevents the lower
		priority frames from being starved of opportunity for
		transmission with only a slight delay to the higher
		priority frames.	Weight Fair
		In the Strict-priority scheme, all top-priority frames
		egress a port until that priority’s queue is empty, and
	Strict	then the next lower priority queue’s frames egress.
		This approach can cause the lower priorities to be
		starved of opportunity for transmitting any frames but
		ensures all high priority frames to egress the switch as
		soon as possible.
Inspect TOS
	Setting	Description	Factory Default
	Enable/Disable	Select this setting to enable the EDS-408A/405A to	Enable
		inspect the Type of Service (TOS) bits in IPV4 frame
		to determine the priority of each frame.
