The 3850 uplink is on Port-channel4, which is connected to the Po1 of a 2960x (10.50.50.41), both configured as trunk, allowing "All".
The 2960x uplink for the router is on the Gi2/0/19 interface, configured as trunk, allowing VLANs 1 and 50.
From my station I can manage (webui and telnet) this 2960x normally at its IP address 10.50.50.41. My station is connected to another edge switch that has an uplink for the 3850 and consequently for the 10.50.50.41.
Sorry for the long information below:
