Hello everybody,
I am facing a problem by two of our customers who are using the same brand switches which are Cisco 4500 Series.
MAC security is applied to all of the ports on the switches. But when a user wants to migrate from a port to another I am facing a "security violation" problem. i.e. The user will migrate from GigabitEthernet6/3 to GigabitEthernet7/5 I am getting "security violation error" on the port GigabitEthernet7/5.
Let me type what I am doing before the migration:
First I am clearing the port security command from the port GigabitEthernet7/5 (new port) and then when I apply port security to the interface GigabitEthernet7/5 (new port) I am getting the same problem.
I have learnt a command which clears the MAC addresses from the ports which is "clear mac-address....(bla bla)". I also apply this command to the interface GigabitEthernet7/5 (new port). But then when I apply port security again I am getting the same port security violation error.
And unfortunately the result turned out to be that the migrated interface GigabitEthernet7/5 works without port security. But I am facing this problem not on all the ports of the switches. Only some ports behave like that.
Summary: A MAC address (user) migrates from port1 to port2. But when port security is applied to the new port (port2) a port security violation occurs.
Can that be an IOS bug or am I doing something wrong?
Regards...
