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.

When moving from OSPFv2 to OSPFv3, there are many changes in the format of the LSAs Type, but the most known changes are: IP prefix informations are no longer carried in Type-1 LSA and Type-2 LSA, new LSAs Type 8 and 9 are added to carry these prefixes.
