vLan Tagging won't stick, changes to back to untagged immediately

[PAiSteve]

Trying to setup interface 49 as a trunk, when I Tag the port, the switch immediately changes it to Untagged. 

Below is my current config

@PAiSteve,

Welcome to the community! 🙂

I suggest to activate image 2 (if ever image 1 is currently the active image).  Once image 2 is activated, make sure to update the firmware on it.  Then, try again to configure interface 49 as a tagged port.  Observe if the same problem will occur.

Regards,
