LACP on 3Com 3CDSG8

[theonek]

Hi! I recently bought one of these switches. So the idea was to use a 2Gb lan with this link aggregation supported by this model switch. I have a 3PCs with dual lan capability. Two of them are with Realtek 8111DL lan chips which supports link aggregation by teaming. The last one is nforce network controllers with the same teaming functionality. But when I connect all PCs to the switch with runing LACP protocol on switch there is no lan, only connected to 2Gb and that is. No browse network sharings or internet. If someone can tell me is this scenario possible to connect every of PCs with 2Gb link aggregation on this switch and if it is possible how to configure the switch to work with these 3 PCs in 2Gb link aggregation or is it better to use only trunking? Thanks!
