So i understand from that last two answers , we can do it by using a script file.
clear ip-security dhcp-snooping entries vlan "Default" ports 7
@Brandon ; we can clear the bindings using the following command .
I think if i can write correct script that finds the ports that goes down , i can do that.
Thanks for the ideas. I will try that , and if i succeed i will share.
