Hi @AshokDaparthi ,

Thanks for a quick response, it helped a lot!

Hi @AshokDaparthi ,

Just one more additional scenario to be clear:

Example 2.

Create QoS Map 1, Dot1P (PCP or Vlan priority) -> TC [0->1, 1->2] (CREATE operation)
Apply QoS Map 1 on the Port 1. (SET operation)
Change QoS Map 1, Dot1P (PCP or Vlan priority) -> TC [2->3, 3->4] (SET operation)

Should we retrieve the same mapping as below?
[0->0, 1->0, 2->3, 3->4, 4->0, 5->0, 6->0, 7->0]

Thanks

Reopening since one more case needs to be cleared..

Set is expected to appended list.

Hi @AshokDaparthi ,

Ok, I see. So how it should handle duplications in old and new list? It`s very complicated implementation as per SAI wrapper...

So at least there is no info about the designed behavior of SAI_QOS_MAP_ATTR_MAP_TO_VALUE_LIST. We should explain to the end-point users what happens under the SET operation here.. I suggest to fix the saiqosmap.h comment,

Thanks

Hi @AshokDaparthi,

I have another question according to SAI_QOS_MAP_ATTR_MAP_TO_VALUE_LIST as appending list.
How can we clear the already configured mapping?

See Example 3:

1. Create QoS Map 1 with mapping [1->2;2->3]
2. Apply QoS Map 1 on the Port 1
3. Change QoS Map 1 with mapping [0->2]
4. Now retrieve QoS Map 1 (size = 3 items)
5. Change QoS Map 1 with empty mapping (as per design, it has no effect?)
6. Retrieve again QoS Map 1 (still size = 3 items) (Now it`s not possible to bring this map as it was on step 1 - with only 2 items)

Thanks
