Maximum bandwidth
By entering a maximum bandwidth you can limit the bandwidth for each
traffic class to a maximum value, regardless of whether you selected
"Weighted Fair Queuing" or "Strict Priority".
X Weighted Fair Queuing (see page 24) requires that the maximum
bandwidth is at least as big as the minimum bandwidth.
X With "Strict Priority", individual high-priority packets with low latency
are processed (see page 24). If the maximum bandwidth is configured
to a value less than 100%, even data packets will lower traffic classes
can be sent in periods of high-priority overloading.
The weighting values range from 0% to 100% of the available band-
width, in steps of 5%.
Description of Traffic Shaping
With Traffic Shaping you have the option of restricting the maximum
bandwidth of an interface.
The values for the bandwidth restriction range from 0% to 95%, in steps
of 5%.
X The value "0" is equivalent to a "no bandwidth restriction" setting.
X The value "95" means that 95% of the bandwidth is available.
If the bandwidth set is temporarily exceeded, the Switch saves the data
and sends it when the bandwidth load has decreased again. Traffic Shap-
ing thus smooths out any overload situations.
If Traffic Shaping is active on an interface, the Switch ignores the band-
widths guaranteed for Weighted Fair Queuing.
