Min/Max Qos Mode Example - Comtech EF Data CDM-570A Installation And Operation Manual

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.
QoS Rule Hierarchy – The QoS Rule Hierarchy is the same as Maximum Bandwidth/Priority
QoS.
QoS Statistics – QoS Statistics are displayed as Maximum Bandwidth/Priority QoS.
L.1.2.1 Min/Max QoS Mode Example
