on the router you have no physical interface assigned to the port channel like you have on the switch

interface Port-channel1

switchport mode trunk

!

interface GigabitEthernet3/1

switchport mode trunk

channel-group 1 mode on

Hello,

 

post the zipped Packet Tracer project (.pkt) file...

And next problem is: Why i cannot create sub onterface on port channel? 

 

 

Hello

What are you trying to achieve here, multilink two rtrs interfaces or this it a switch with L3 routing as a rtr doesn't have PC capabilities

Also it look likes one side is a L2 aggregation and the other is L3 which will not work.
