Port Classification
Port classification is another way to manage network traffic through the device. Port classification 
allows you to configure one or more device ports to prioritize and forward untagged frames 
according to a specific protocol type classification rule. By default, when a frame is received that 
already contains an 802.1Q frame tag, frame classification is not implemented. Instead, the frame 
is processed by the Matrix E1 device according to the information contained in the 802.1Q frame 
tag. 
When configuring the ports, you can
display the current classification, and entries of each classification rule, 
assign priorities to classification rules, 
assign an 8-bit Type of Service (ToS) value to incoming IP frames, 
add/delete a priority and associated protocol entry, 
overwrite default precedence levels assigned in an 802.1Q tagged frame, and 
overwrite an existing ToS value. 
NOTE: When the priority tag override feature is enabled on a port, 802.1Q frame tags 
received on that port are assigned a lower precedence, allowing MAC address matching 
and other types of priority classifications to receive higher precedence
