The Quality Of Service General Screen - ZyXEL Communications VMG Series User Manual

Traffic Policing
Traffic policing is the limiting of the input or output transmission rate of a class of traffic on the basis of
user-defined criteria. Traffic policing methods measure traffic flows against user-defined criteria and
identify it as either conforming, exceeding or violating the criteria.
Traffic Rate
(Before Traffic Policing)
The Zyxel Device supports three incoming traffic metering algorithms: Token Bucket Filter (TBF), Single
Rate Two Color Maker (srTCM), and Two Rate Two Color Marker (trTCM). You can specify actions which
are performed on the colored packets. See
metering algorithm.

Click Network Setting > QoS > General to open the screen as shown next.
Use this screen to enable or disable QoS and set the upstream bandwidth or assign traffic priority. See
Section 10.1 on page 211
When one of the following situations happens, the current WAN linkup rate will be used instead:
WAN Managed Upstream Bandwidth is set to 0
1
WAN Managed Upstream Bandwidth is empty
2
WAN Managed Upstream Bandwidth is higher than the current WAN interface linkup rate
3
Note: Manually defined QoS is ignored when Upstream Traffic Priority is selected.
Note: Upstream Traffic Priority automatically assigns a traffic priority level based on the
selected criteria.
Note: To have your QoS settings configured in other QoS screens take effect, select None in
the Upstream Traffic Priority field.
