I have a 3650-24 switch that I just cut out of the box to do some software upgrade tests on. I upgraded it from 3.6.8 Bundle mode to 16.6.5 Install mode. The upgrade went well. Now I want to get the switch on the network so I can scan it for vulnerabilities.
I connected the switch to a production switch so the 3650 can pull an IP via DHCP. The production switch port is an access port on vlan 100. The 3650 has no config with the exception of a vlan 1 interface set to DHCP.
The port, 1/0/24 on the 3650 keeps going to spanning-tree blocked.
This is what I always do and it always works when testing new software updates.
What is different about 16.6.5 that is causing this access port to go down? How do I get around this new behavior?
