IMPORTANT
15.4.4.2 Minimum/Maximum Bandwidth QoS Mode
QoS Rules can be assigned to up to 32 different types of flows to be defined by the user.
Flows can be defined by any combination of Protocol (FTP, UDP, RTP, etc.),
Source/Destination IP (specific or range), and/or Layer 3 Source/Destination Port.
Weighted Random Early Detection (WRED) – The Min/Max BW QoS mode allows
the user to select Weighted Random Early Detection (WRED). Without WRED, output
buffers fill during periods of congestion. When the buffers are full, tail drop occurs; all
additional packets are dropped. Since the packets are dropped all at once, global
synchronization of TCP hosts can occur as multiple TCP hosts reduce their transmission
rates. As the congestion clears, the TCP hosts increase their transmission rates, resulting
in waves of congestion followed by periods where the transmission link is not fully used.

Once the QoS Rules are defined, each type of traffic flow
should be isolated and sent to verify that it is being sent in
the intended QoS Rule.
