Set the timer during which the

The port-security timer disableport command is used in conjunction with the port-security
intrusion-mode disableport-temporarily command to set the length of time period during which the
port remains disabled.
If you configure the NTK feature and execute the port-security intrusion-mode blockmac command
on the same port, the switch will be unable to disable the packets whose destination MAC address is
illegal from being sent out that port; that is, the NTK feature configured will not take effect on the packets
whose destination MAC address is illegal.
