Figure 5-43 802.1p Priority
Priority Tag: The priority tag defined in IEEE802.1p.
Corresponding Priority Class: Indicates the inner priority classes of switch. The tagged frames are classified into four classes inside the switch: lowest, lower, higher and highest. When the “Weighted” priority rule is configured, a 1,2,4,8 weighting is applied to forward these four classes of packets.
Further explanation
In IEEE802.1p priority mode, when a switch port receives an untagged frame (a frame without priority tag), the port's default priority tag will be inserted into the frame before any other process.
