I am receiving a PPPoEoQinQ mirrored traffic from another Huawei switch to 3560G switch. I am able to see this traffic on 3560G port. When I mirror this traffic (SPAN Configuration) to destination port, the traffic is zero on destination port. i.e I am not able to mirror this traffic. Where is the limitation. When the traffic is received as normal L3 packets the 3560G mirrors it and same traffic as available on destination port.
