I think you have your etherchannel concepts confused. In a single connection between two switches, you can either have an L2 connection, or an L3 connection but not both. An etherchannel is no different, it can be L2 or L3 but not both.

I agree with the other comment that posting your configs would be helpful. Look at the port-channel interface configuration. Is there a 'switchport mode' command present? What does it say? An L2 interface would say "switchport mode trunk" or "switchport mode access". An L3 interface shouldn't have any 'switchport' configs and it would just have an IP Address assigned to it.

My other question still stands though... Where does the router/default gateway on the 192.168.1.0/24 subnet live? Is it on the switch or the router?
