Hello,
I spotted a problem while creating network in Packet Tracer. I've connected 3650-24PS switch to ISR4321 router by two copper straight-through cables and then tried configuring EtherChannel on both devices. Setup is working fine until I save and reopen PT. Then Port-Channel 5 on switch has status of down, but router's one keeps being up. I don't know if I made some mistake during the configuration, but I found this discussion which faces same problem. I hope there is something I can do to make this working without changing the switches. I attach project file if someone finds it useful.
