Layer 3 QoS Min-Max Mode

In Min-Max mode, up to 32 QoS rules can be configurable using source IP subnet, destination IP
subnet, source port range, destination port range, and protocol. For each created rule, you can
also set the QoS treatment, such as guaranteed minimum bandwidth, maximum clipping
bandwidth, WRED enable or disable, and filter rule.
When WRED is enabled for a specific queue, QoS randomly drops packets after reaching 50% of
the QoS queue.
When the FILTER option is enabled for a rule, Layer 3 QoS provides the ability to filter the packet
completely.
