Executing the command switch port port-security mac-address 00C0.35F0.8301 on a port (F01) in interface configuration mode enables port security and sets a specific MAC address as the allowed device for that port. This means only the device with the MAC address 00C0.35F0.8301 will be permitted to send traffic through the port. If another device attempts to connect, the switch will either drop the traffic or shut down the port, depending on the configured violation action. This enhances network security by preventing unauthorized access.
Yes, By default port security is disabled on a Cisco switch. If it is enabled the default violation mode is shutdown with a maximum MAC address count of 1. Even if port-security is enabled it will not place a port into the shutdown state until either MAC address sticky or a static MAC address is configured on the port.

The switchport port-security protect command is used in Cisco switches to enable port security on a specific switch port. When this command is configured, the port will allow traffic only from MAC addresses that are already learned and stored in the port's memory. If an unauthorized MAC address tries to connect, the switch will drop the traffic from that address, effectively preventing unauthorized access while allowing legitimate traffic through. This security measure helps to mitigate risks associated with MAC flooding and unauthorized devices.

Yes, most protocols have the ability in a configuration file to state which port they will use (as a default),but this can be changed, and is frequently changed for security purposes.
