Cisco’s Port Security feature just happens to be one of those switch features that can confuse people until they’ve configured and tested it a few times. One challenge comes from the fact that you can enable port security with one command on an interface (switchport port-security), with many default settings, but then you can also re-configure a variety of other settings. Understanding each setting, and remembering them all (and when to use each) poses a challenge.
In this post, you’ll get to enable port security with some basic features, just to get more exercise with choosing which options to leave as defaults, and which to configure.
Hello Mr, Wendell, the requirements text state that the interfaces to be configured are F0/3 & F0/0, but the diagram shows otherwise.
Hi,
Yep, all true. Several mistakes in the lab. I’ve reviewed it, and I think I caught them all. All text, examples, etc should refer to the various switches’ F0/1 ports. Thanks for letting me know.

Hi sir,
I downloaded CPT version but, it was incompatible with the ver I’m using(7.2.0.0226). Paper/editor & Cisco modeling labs versions don’t work as well. I recommend to type commands in .txt file and upload for us.
Thanks
Hi Davood,
Thanks for the input and suggestion. Two responses:
1) What would you like to see in the text file you suggested that’s not already available on the page? This page includes all the initial config for each device as well as the configuration needed to answer the lab. I’m not sure what else I could supply for you to do the lab – please clarify.
2) If you update to a more recent version of Packet Tracer, you can do the labs in packet tracer. I believe you’d have a much more useful experience doing that rather than making these a paper exercise. Here’s a page that details how to get the latest Packet Tracer for free. https://blog.certskills.com/ptinstall/
Hope this helps,
Wendell
When I try to add the mac-addresses as a maxium of 2 it does not let me enter two mac addresses. I have to raise the max to 3 to enter the mac address. Why does this happen?
Hi Rob,
I am wondering if you bumped into a Packet Tracer bug/feature. I’ll take a look in a few days – teaching for the next few. In the mean time, on a hunch:
First shutdown the port (that is, get into config mode, then interface mode, and issue the “shutdown” command.
Then configure port security.
Then issue a “no shutdown” command.
I’m wondering if the switch is learning the attached PC’s MAC, and then PT is not letting you configure the 3rd MAC address.
More in a few days.
