What kind of module is in the 2800. You may want to check out the following link which discusses etherchannel only being manual and for link-redundancy on high-speed WAN cards:
Q. Is Cisco EtherChannel supported? A. Yes. Cisco EtherChannel is supported for link redundancy, and can only be set up manually. Negotiation protocols such as Link Aggregation Control Protocol (LACP) (802.ad) and Port Aggregation Protocol (PAgP) are not supported.
Additionally, I don't even think one of those routers will support that kind of bandwidth. This link also has some more information if the card is not the WAN card:

Thanks for replies. I am just starting to think if it is supported on this router version and modules?
While I agree with Merv based on my above post indicating that the router doesn't support what you need, I am also still pretty sure that router will not handle that kind of throughput. So while I would do the equal cost load sharing via layer 3, you may want to check the specs of the router as 2811s may not push that kind of routed throughput.
The Etherchannel on builtin ports of 1800/2800/3800 series routers is not supported. Therefore, it may be configurable, it may show signs of actually working (or not) but when it's not supported - it may not work (and usually doesn't).
You may get some info about this here:
"Q: Do the LAN interfaces on the platforms support aggregation through EtherChannel or PAGP technologies?")
"except that Cisco EtherChannel? is not supported on the on-board Gigabit Ethernet interfaces")
