DSCP values range from 0 to 63. Some common values include Default (0), which is used for best-effort traffic, AF31 (26), AF32 (28), and AF33 (30), which are used for priority traffic, and EF (46), which is used for expedited forwarding of voice over IP (VoIP) traffic. The specific use of these values can vary depending on the network’s QoS policy.
