[@abdulhaquemohammed6478]

Hi there, Thank you very much for uploading this video. It was to the point and informative. However, when I was practicing, I could not see any violations occurring. The security violation count is '0' while the security action is 'Restrict'. The link is not going down. I switched my PC with a laptop and vice-versa (in the Cisco packet tracer) yet no changes. Please advise. Thanks!

[@Corswain]

Did you set the allowed MAC address to something like he did in the video around 3mins in?

[@RebazCh]

Every Time I Understand With Your Videos Very Simply & Easy , Thanks Man.😍

[@Certbros]

[@RebazCh]

[@benardnassary5054]

I will appreciate if you can finish the part of recovering port from secure down to secure up after violation occur.

[@TechnicalMalayalam]

Can you recommend a good book to learn more about Cisco IOS? Not doing any exams or anything, just curiosity...I've got a few managed switches to play with.

[@3jadon]

Nice Thank You

[@zuliano05]

what is the funtion the command with stiky included???

[@Certbros]

The sticky command learns the mac addresses and stores them in the running config. Check out the below link.

[@diogo8500]

Question: When setting port-security violation to protect or restrict and the interface goes down due to a violation, does it go back up after a while? Or does it have to be manually brought up?
Thanks!

[@virescon]

Restrict & protect violations will recover automatically given they meet the requirements. Shutdown will result in the interface going into the err-disable state which will need to be rectified.

[@jakescott9214]

It returns the error when I enter the mac:
Switch(config-if)#switchport port-security mac-address 4444.4444.4444
Total secure mac-addresses on interface FastEthernet0/1 has reached maximum limit.
