ehter channel issue...

Hello All,

             I have a query regarding ether channel layer 2.

In The network (STP running on) I firm the the layer 2 ether channel in
between switches. I want to know when the Root bridge sent the BPDU on which
port it will receive because STp assume this is as one interface. as per my
observation it sent the bpdu on first physical interfce in etherchannel
group. why is it so.
