Etherchannel and misconfiguration

Hi,

My 2 3750 are connected with 2 GiGe Link with etherchannel mode ON.

i wanted to add a VLAN on the trunk, so i did the "switchport trunk allowed vlan add" command on the 2 giga interface instead of the "logical port channel interface". so the 2 interfaces Giga have been immediatly "suspended" si the etherchannel was down

is it possible to devalidate this feature in order to avoid the type of probleme with a misconfiguration ?
