Hi
I want to apply security to a switch allowing to connect several machines in different ports of the same switch.
To do this, I issued the command
# switchport port-security
# switchport port-security maximum 3
# switchport port-security mac-address sticky
# switchport port-security mac-address sticky X.X.X
# switchport port-security mac-address sticky Y.Y.Y
# switchport port-security mac-address sticky Z.Z.Z
When I do this on the first interface, I have no problems. Doing in the second, I get a message saying that the MAC address is already used. What I want is that in the same room, computers (which are always the same) can switch places with each other.
