Is it possible to configure port security on multiple ports at a time? Looks at the steps, it looks like it’s not possible because I have to get into the interface I’m configuring then use the command. I’m just curious and if it’s not possible is there a reason it’s not allowed?
Also, am I missing a command that will show me more details on why the port went down or am I suppose to use my troubleshooting knowledge to figure out the possible reasons why the port went down?
An example, I configured the switch to only allow a laptops mac address on fa0/1. I put a hub between the laptop and fa0/1 so I can plug a PC into the hub and test the port security. The port goes down but I only get (%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to administratively down).
I was hoping to get something else like, port down due to security violation or something.
