Advanced Port Priority Configuration Screen Fields
The following information briefly explains each Advanced Port Priority
Configuration Screen field.
Priority (Read-Only)
This field displays the eight priorities, 0 through 7.
TX Queue (Selectable)
This field enables the frames with a certain priority to be mapped to transmit
according to one of four TX queues (0 through 3) with 0 being the lowest transmit
level. Table 11 lists the TX Queue default values according to frame priority.
RX Priority (Read-Only)
This field displays the eight priorities, 0 through 7.
TX Priority (Selectable)
This field enables the frames with a certain RX priority to be changed to transmit
according to a different TX priority (0 through 7). For example, all frames with an
RX priority of 3 could be regenerated with a TX priority of 5. The new value
would also be inserted in the VLAN tag if the frame is tagged as outbound.
The regenerated priority determines the correct queue as defined in the
Priority/Queue Mapping. Table 12 lists the default values for the TX Priority
settings according to RX priority.
Port # (Modifiable)
This field allows a user to enter the number of the port to be configured. After
entering a port number, use the arrow keys, or press ENTER, to refresh the screen
and show the current settings for that port.
Default Port Priority (Selectable)
This field sets the default port priority (0 through 7) of the port selected in the Port
command.
