Hi Henrique, yes I did. The agent I spoke with confirmed the command I used, and mentioned it shouldn't have cause any problem given the configs on the switch. He was going to look into it further but he had to close the case because he realized my company's support had expired a month ago. I will have to wait for support to be renewed before I can open the case again. Thank you for asking for updates on this.
However, I do have a question: Is it bad that I removed those ports from Default vlan while they were actively passing traffic? This baffles me because I have had to always to this with no issues.
