QoS > 802.1p/DSCP Default Priority
Quality of Service (QoS) is an implementation of the IEEE 802.1p standard that allows network
administrators to manage traffic for important functions that require more bandwidth or 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. This means that the
Switch will handle traffic from higher priority ports first. For packets that are untagged, the Switch will assign
the priority depending on your configuration.
