Don't see how this is possible. On what platform does this configuration exist?

Have you tried reloading the device to see if it clear things up?

Yes i reboot same result.

here's what i found something weird.

Upon login again today: noticed that there's only one Po1

!
interface Loopback0
 ip address 10.10.10.10 255.255.255.255
!
interface Port-channel1
 switchport mode trunk
!
interface FastEthernet0/0

but after shutting down.. theres 2 PO1 (i tried to removed as well but the PO1 w/ mode trunk remains)

Po1                            admin down     down     
Po1                            up                    down 

and the run config shows like this

!
interface Port-channel1
 no ip address
 shutdown
 hold-queue 0 in
!
interface Port-channel1
 switchport mode trunk
!
interface FastEthernet0/0

It is tough to find documentation but this may provide an answer. Look at the attached link, specifically the 7200 router config. The same may apply in that by defining the port-channel as a trunk you need the major interface and then the L3 sub interfaces in their respective VLANs.

Never had to do this myself, but hope it clears things up.
