Priority Tag ¾ : The priority tag defined in IEEE802.1p.
Corresponding Priority Class ¾ : 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 tag1, the port's default priority tag will be inserted into the
frame before any other process.
