How to build Etherchannel between Procurve E2510G with 3Com 4800G?

[C3P]

Can someone help me on the comfig? I'm connecting the procurve(port 45, 46) to 3Com (port 11, 12) with 2 fiber. I would like to build a etherchannel between the 2 switches. However, I'd tried many combination trunk/ LACP configuration but it doesn't work. Now it is running on single link and the network seems to be stable. Once I plug in the second link on it, the network will flap. 

Thanks in advance.

Either configure Procurve trunk and 3Com static or Procurve LACP and 3Com LACP active.

Thank you for suggestion. Do you have any example on the 3Com Configuration for LACP Active?
