Port MAC security configuration guidelines and considerations
A port mode change is not allowed when port security is enabled on the interface.
If a port-security-based change occurs when a port is shut down, the shutdown timer is not triggered. Consequently, the user must restore the full functionality of the port.
When port security causes a port to be shut down and the user manually changes the shutdown time, the shutdown timer is reset and the timer starts with the new shutdown time.
Static MAC addresses cannot be configured on a secure port. They must be configured as secure MAC addresses on the secure port.
