QoS Configuration

QoS
Different applications make different demands on networks. For pure file transfer, the overall
throughput is decisive, while the individual latency and loss rate is less significant. For real-
time communication, for example Voice over IP, on the other hand, latency, jitter and the
loss rate are much more important because they directly affect understandability.
Transmission priorities
The X-300/400 IE switches support CoS to Queue and DSCP to Queue Mapping, with which
packets from different sources with different priority can be forwarded. To allow downward
compatibility with earlier firmware versions, DSCP Mapping is disabled in the default setting.
