With Violation Protect mode, When the number of port secure MAC addresses reaches the maximum limit allowed on the port, packets with unknown source addresses are dropped.You have to remove the secure mac-addresses below the maximum allowed number in order to learn a new MAC or allowing a host on the port.You are not notified that a security violation has occurred.
With Violaion restrict, the same process happens but a, SNMP trap is sent, syslog message is logged in the syslog server and the voilation counter increases.
I use two PCs in my scenario. One is the PC that I want to use port f0/5, for example. And another PC that acts like a non-secure that wants to attach to a port that I designated it for PC 1.
Note I use "protect" option for the violation in the example.
I use the MAC address of the PC 1 to setup a secure switch port. I then takes off the PC 1 and take in PC 2 in the f0/5.
As expected, the port is received a violation. Right?
But I can ping or telnet the switch with PC 2, actually. However, I cannot ping another IP address. It seems that the switch is dropping the packets. Is it normal?
I pull out the PC 2 and take in the PC 1 in its port again. I can ping or telnet the switch, but I cannot ping another IP address. It seems that the switch is dropping the packets for a PC that I setup its MAC address for security (PC 1). Is it normal?
