Can a switch generate PFC Pause?

Can a switch generate PFC Pause?

I want my EXOS 670 switch to generate pause frames when it receives certain traffic or when its buffer is full. currently when i send the traffic from both ends it passes by without dropping. All packets sent are received. How to make one end stop sending one the other end is sending packets? in other words how to enable PFC on switch .

It seems that you are using an older EXOS code.

This command was first available in EXOS 15.6.2.

Hi Danial, did you try the same command for rx-pause as well?

Do you see any counter incrementing to the commands below?

show port 1,2 flow-control tx-pauses
show port 1,2 flow-control rx-pauses

No i tried this but its not working. I have the two ports in a single vlan and i applied the same command but both the ends can still receive the frames..

Hi Danial, I haven't tried that yet, but I guess you can accomplish that with the command below:

enable flow-control tx-pause priority 3 ports 2

The default dot1p priority values are:

802.1p Priority Value QOS Profile
1 QP1
2 QP1
3 QP1
4 QP1
5 QP1
6 QP1
7 QP8

Yes thank you! what i am doing here is attach a test center to exos on ports say 1 and 2. now i want is if port 1 and 2 sends frames simultaneously port 1 should be paused for a while. how can i do it inside the switch because both ports can have priority 3 traffic how should i pause priority 3 traffic of say port 2.
