Hi everbody!
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.
Thanks in advance!

Hi
I don't understand what is you issue exactly
But it is some problem in your configuration
You have not use port security in you core and distribute layer
Let me know about your L3 or L2 packet switching. Maybe your packet drop issue is because of these.

Hi Ana,
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.
maybe thats why...
plz Rate if it helped.

I want to use the same laptop (and the same mac address if possible) when trying to display some ISE features in different switches, having both 802.1x and port-security enabled.
I want to know if it's possible, and how to make it possible.
So, I did know it's because the protect mode, but I want to prevent the dropping to happen even with port-security enabled.

Hi,
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.
Thanks & Regards,
Antonin
