Configuring Quality of Service (QoS)
Three methods of traffic classification are supported:
• 802.1 priority mapping
• DSCP priority mapping, using tag values
• Priority mapping per bridge port.
• Queue profiles
The classification method is chosen using the Priority Classification menu.
Four traffic queues are supported, which can be assigned priorities using the
Priority Mapping menu.
Class 0 (default) has the lowest priority and Class 3 has the highest priority.
These queues are priority queues, that is, packets arriving with lower priority will
only be transmitted after all packets with higher priority have been transmitted. It
implies possible starvation of the lower priority traffic in case the higher priority
traffic uses all of the available bandwidth.
