Trying to Prevent Router/Firewall from Connecting to Cisco Switch

 

Is there a way to configure a switch port on a Cisco Switch to disable when a router/firewall (used in homes ie Linksys, Dlink etc ) is plugged into it. I would like to use port lever IOS commands.

We are running the following code:

WS-C3750X-48       12.2(53)SE2           C3750E-UNIVERSALK9-M

Hello, There is no such a

Hello,

 

There is no such a command that can dynamically do this kind of stuff.

 

What you can do is get the MAC address of the box you want to block and then create a L2 ACL blocking all of the traffic comming from that specific box but no way you can say "block access from future boxes that are either a Cisco ASA Firewall o Juniper SRX Firewall" No way my friend.
