correct.

Yes, you need to configure the neighboring switch as well, take a look
at
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1214ea1/3550sc
g/swethchl.htm.
Please make sure to configure the switch with "mode on" (i.e. disable
PAgP/LACP) via "channel-group 1 mode on" since the router does not
support PAgP/LACP..
