I am working in an AVB project with a Summit X440-8t switch (EXOS 126.96.36.199). I have a question about the AVB class priorities assigned to Class A and Class B, and the possibility to change them.
IEEEE P802.1p defines default attributes for traffic classes:
- for Class A the ClassPriority 5
- for Class B the ClassPriority 4
The ClassPriorities are encoded in the VLAN tags in the corresponding PCP values.
It looks like the switch has the following default attributes for traffic classes:
- for Class A the ClassPriority 3
- for Class B the ClassPriority 2
My question is:
Is it possible to change in the switch the class priorities for Class A and Class B? I would like to have for Class A the ClassPriority 5 and for Class B the ClassPriority 4.
The reason why I would like to increase the class priorities is that I want to run the AVB streams with higher priorities than other TCP traffic that runs in the same AVB domain on priorities 3 and 2.
Help would be appreciated!
