6.4 QoS/Priority
Communication networks transmit a number of applications at the same time
that have different requirements as regards availability, bandwidth and
latency periods.
QoS (Quality of Service) is a procedure defined in IEEE 802.1D. It is used to
distribute resources in the network. You therefore have the possibility of
providing minimum bandwidth for important applications. Prerequisite for this
is that the end devices and the devices in the network support prioritized data
transmission. Data packets with high priority are given preference when
transmitted by devices in the network. You transfer data packets with lower
priority when there are no data packets with a higher priority to be
transmitted.
The device provides the following setting options:
You specify how the device evaluates QoS/prioritization information for
inbound data packets.
For outbound packets, you specify which QoS/prioritization information
the device writes in the data packet (e.g. priority for management packets,
port priority).
Note: Disable flow control if you use the functions in this menu. The flow
control is inactive if in the

the "Activate Flow Control" checkbox is
