QoS Configuration for a Management Station
Introduction
As stated previously, the QoS feature enables prioritization of traffic and allocation of the available bandwidth based on
that prioritization. The system is designed in such a way that higher priority traffic preempts lower priority traffic, keeping
lower priority traffic on hold until higher priority traffic finishes. This mechanism ensures that the available bandwidth is
always given first to the higher priority traffic; if all the bandwidth is not consumed, the remaining bandwidth is given to the
lower priority traffic.
If QoS is not configured properly, the system can become difficult to access in heavily loaded networks. One of the side
effects of this misconfiguration is ping time-out, which is usually interpreted as a disconnection of the pinged node.
However, with the correct QoS configuration, every node in the network can be reached at any moment.
The configuration instructions that follow explain how to configure the system so that configuration parameters can
always be changed, and ping requests and responses get higher priority in order to show the actual connectivity of the
pinged node.
The configuration suggested here assumes that the whole network is managed from a single work station, called the
management station. This station can be connected anywhere in the network, and can be recognized by either its IP
address, or by its MAC Ethernet address if the network uses DHCP.
In this configuration, any traffic coming from or going to the management station is treated as management traffic.
Therefore, the management station should be used only for configuration of the TMP.11 nodes in the network and to
check connectivity of the nodes, but it should not be used for any throughput measurements.
CAUTION: While this QoS configuration is used, the TCP or UDP throughput should not be measured from the
management station.
