Min/Max (Minimum/Maximum Bandwidth) QoS Mode

In Min/Max mode, up to 32 QoS rules can be configured using source/destination IP subnet,
Layer 3 source/destination port range, and protocol (FTP, UDP, RTP, etc.). 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.
Minimum Bandwidth – Minimum specification that allows a committed information rate (CIR)
to be applied to user-defined classes of traffic; otherwise, the default of no minimum bandwidth
can be selected.
Maximum Bandwidth – This can be assigned to a flow to restrict the Maximum Bandwidth that
any particular flow will utilize; otherwise, the default of no bandwidth restriction can be
selected.
WRED – The Min/Max QoS mode allows selection of Weighted Random Early Detection (WRED).
When WRED is enabled for a specific queue, QoS randomly drops packets after reaching 50% of
the QoS queue.
Filtering – Any specific flow can be designated as filtered (see Max/Pri QoS Mode).
When the FILTER option is enabled for a rule, QoS provides the ability to filter the packet
completely.
