N-Command User Manual
A policer typically drops traffic.
Differentiated Services Code Point (DSCP) values can be configured in N-Series devices if QOS is required on the
network.
A shaper typically delays excess traffic using a buffer, or queueing mechanism, to hold packets and shape the flow when
the data rate of the source is higher than expected.
Cannot be used with N2300 series.
Note that this command has to be assigned individually per port that is assigned to that VLAN. However it is not
necessary with ports on the same switch that will not be set up on the same VLAN as the N-Series devices.
