Trying to configure PAgP with IPv6 but there is no needed command.

I need configure PAgP and IPv6 on L3 switches, but I Can`t do this.

Hi @gastrit 

On L3 switches you must first encapsulate the interface and then leave it in trunk mode:

SW2(config-if)#switchport trunk encapsulation dot1q

SW2(config-if)#switchport mode trunk

If you have other questions, just post them to try to help you

There is no such command as switchport trunk encapsulation dot1q

HI @gastrit 

Compress (winzip) and attach your exercise to check the settings you have entered.

Hi @gastrit 

I've made these changes:
1-In SW2 change the interface that connects to your LAN, in this way, both switches have interface g1/0/1 towards their LAN.
2-Only g1/0/1 interfaces maintain IPv6 addressing.
3-You should remember that all interfaces that are members of a PortChannel must have the same configuration.
4-You should remember that when you enter the no switchport command, you disable the layer2 functions of that interface, including trunk mode.
An interface cannot be a routed port (no switchport) and at the same time be in trunk mode.
5-Once the PortChannel is created, the changes must be made on the PortChannel interface.

I attach the file with these fixes and with the PortChannel1 UP

firstly configure trunk dot1q under interface. "switchport trunk encapsulation dot1q"

There is no such command as switchport trunk encapsulation dot1q

Change switch model on PACKET tracert or you can use other tools like: GNS3, EVE-NG, VIRL and so on :)
