I have a problem with a switchport on an N2048P. The port is not working anymore. This is my test port. The last thing I did, was reconfigure it from trunk to access while it was up. After that the port would forward any traffic. I tried:
- Update from 6.1.2.4 to 6.2.1.6 (i.e. a reload)
- going from trunk to access to general and back to access
- Hot-Swapping the affected switch in the stack with another one
The Problem persists. The swapped switch has the problem and kept it until it was reset to factory defaults. The current output of the switch is:

The combination of State: Forwarding and Role: Disabled seems strange to me. Interesting is also, that interface detail misses two lines after Flow Control compared to another normal port.
Flow Control: Enabled
Port: Gi4/0/4
VLAN Membership mode: Access Mode
Any ideas on where the config is borked?
