I am using 3560G to receive traffic consisting PPPOE from another switch. Now I want to mirror (SPAN) this traffic to a destination port. But this switch does not show any traffic on destination port for PPOE traffic.

Hello Manish,
this is strange PPPoE frames are still ethernet frames it shouldn't make any difference.
May you provide more details on how you have configured SPAN ?
It is the source port a trunk port ?
Hope to help

Thanks, We have tried making the source port as trunk port also. In both cases it shows the traffic on source port in packets and bits but on destination port traffic is zero.
We are receiving the traffic from a Huawei switch. We also tested by putting a Dlink converter (Gigabit optical to gigabit copper) in between Huawei switch and a server. The tcpdump clearly shows the PPPOE packets and its details. But in place of server when we connected the 3560G port and tried it to mirror there was no traffic on destination. In same environment the traffic received from other non-Huawei switch, we are able to mirror.
