Chapter 1: Changes to Local Management Screens

Use the arrow keys to highlight the SAVE command at the bottom of 
the screen.

Press ENTER. The message “SAVED OK” displays and the setting is 
saved.

The Advanced Port Priority Configuration screen, 

set the Priority/Queue Mapping and Priority Regeneration for a particular 
port or change the default port priority. Priority/Queue Mapping is used to 
set the transmit (TX) queue (0 or 1, with 0 being the lowest level TX 
queue) for each frame priority. 

For example, if the TX queue is set to 1 for those frames with a priority 1, 
then those frames would be transmitted before any frames with a priority 
that has the TX queue set to 0.

Priority Regeneration is used to classify different types of traffic by 
reprioritizing received frames to a different transmit priority. For 
example, the frames associated with a particular type of traffic that have a 
received (RX) transmit priority, or a port default priority, of 3 could be 
changed to have a transmit priority of 5.

To access the Advanced Port Priority Configuration screen from the 
Priority/Multicast Configuration Menu screen, use the arrow keys to 
highlight the ADVANCED PORT PRIORITY CONFIGURATION 
menu item and press ENTER. The Advanced Port Priority Configuration 
screen displays.

The Advanced Port Priority Configuration screen does not 
display when the operational mode of the device is set to 
802.1D SWITCHING.
