QoS > 802.1p/DSCP/ToS
QoS is an implementation of the IEEE 802.1p standard that allows network administrators to reserve
bandwidth for important functions that require a larger bandwidth or that might have a higher priority, such as
VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing.
Thus with larger bandwidth, less critical traffic is limited, and therefore excessive bandwidth can be saved.
The following figure displays the status of Quality of Service priority levels of each port, higher priority means
the traffic from this port will be first handled by the switch. For packets that are untagged, the switch will
assign the priority depending on your configuration.
