6.1 Meters and queues
Meters
Meters are used to limit the bandwidth for a certain interface.
This is done by setting a drop and a mark rate. How this is done will be discussed
later on in this chapter.
Queues
As seen before in
the SpeedTouch™ supports up to 6
queues. These queues are used to prioritize data. Each queue handles a range of
internal classes. As seen before a packet is associated with an internal class by
means of embedded priority indicators as DSCP, VLAN priority or by defining your
own specific rules.
The table below shows these relations more in detail.
