The default setting is No. Observe the following when setting the
Override Priority.
❑ When the Override is set to No and the Port Priority Level is set to
0, all incoming packets are directed to the queue indicated in the
Tag Priority Level.
❑ When the Override is set to No and the Port Priority Level is set to
1, all incoming packets are directed to “high” priority queue.
❑ When the Override is set to Yes and the Port Priority Level is set to
0, all incoming packets are directed to “low” priority queue.
For more information on the assignment of the priority queue,
refer to Class of Service Overview on page 162.
Note
The tagged information in a frame is not changed as the frame
traverses the switch. A tagged frame leaves a switch with the same
priority level that it had when it entered, regardless of the priority
queue that handled the frame.
