How to make portchannel between layer 2 and layer 3 switch?

[rrairineo1]

No it needs to match both sides c, cant be ip based on l3 and not on l2,so it has to be layer 2 each side only

just bundled trunk ports really like below , far side would be channel-group active if using lacp

interface Port-channel10
 description xxxxxxxxxx
 switchport trunk allowed vlan 1-1005
 switchport mode trunk

interface GigabitEthernet1/0/3
 switchport trunk allowed vlan 1-1005
 switchport mode trunk
 channel-group 10 mode desirable

interface GigabitEthernet1/0/4
 switchport trunk allowed vlan 1-1005
 switchport mode trunk
 channel-group 10 mode desirable

Nope, fraid not.

You can have a L2 both sides.

You can't have a L2 Trunk one side and a L3 interface the other side.

Just because its a L3 doesn't mean it only does L3 functions, you can happily have a L2 etherchannel between a L2 switch and a L3 switch.
