Prevent dropping of packets in a port-security / 802.1x environment
I have a dedicated laptop I use to display some features, when I change the wired connection from a switch to another switch, it drops the packets even though I do authenticate correctly, I have 802.1x configured in the access switches and port-security in the aggregation/core switch, I have configured port-security protect mode, otherwise the aggregation/core switch could just shutdown the port.

when you configure a port's violation mode in Protected mode, instead of shutting the port down, it drops packets with unknown source addresses until you remove a sufficient number of secure MAC addresses to drop below the maximum value.

Can you please post the port configuration of your aggregation/core switch. My view is you are using trunks in between the core/aggregation and access switches and obviously you wish to stay within the same Vlan with your laptop. I understand that you are using port-security at the core/aggregation switch ONLY in addition to 802.1X authentication with the access switches.
