8.4.6 Handling of traffic classes
For the handling of traffic classes, the device provides:
X Strict Priority
„
Description of Strict Priority
With the Strict Priority setting, the device first transmits all data packets
that have a higher traffic class before transmitting a data packet with the
next highest traffic class. The device transmits a data packet with the low-
est traffic class only when there are no other data packets remaining in
the queue. In some cases, a high level of data traffic can prevent packets
with lower traffic classes from being sent.
In applications that are time- or latency-critical, such as VoIP or video, this
method ensures that high-priority data is sent immediately.

mode” (see Switching:VLAN:Global)
