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. 34
