Switch port security is a feature that allows you to control which devices can access a switch port and prevent unauthorized access or attacks. There are two main ways to configure switch port security: static and dynamic. Static port security requires you to manually specify the MAC addresses of the devices that are allowed to connect to a port, while dynamic port security automatically learns and stores the MAC addresses of the devices that connect to a port. In this article, you will learn what are the benefits of using dynamic port security over static port security.

1 Simplicity and scalability
One of the benefits of using dynamic port security is that it simplifies the configuration and management of switch ports. You do not need to know or enter the MAC addresses of the devices that connect to a port, as the switch will learn them automatically and store them in a table. This also makes it easier to scale your network, as you do not need to update the configuration every time you add or remove a device from a port. You can also set a maximum number of MAC addresses that can be learned per port, to limit the number of devices that can access a port.

2 Flexibility and mobility
Another benefit of using dynamic port security is that it allows you to have more flexibility and mobility for your devices. You can move a device from one port to another without changing the configuration, as long as the new port has the same security settings and the device's MAC address is not already learned on another port. You can also use dynamic port security with sticky MAC addresses, which means that the switch will retain the learned MAC addresses even if the device is disconnected or the switch is rebooted. This way, you can have a balance between security and mobility, as the switch will only allow the devices that have previously connected to a port to reconnect to it.

3 Security and monitoring
A third benefit of using dynamic port security is that it enhances the security and monitoring of your network. You can enable violation modes and actions on your switch ports, to specify what happens when an unauthorized device tries to connect to a port. For example, you can shut down the port, drop the packets, or send a notification to the network administrator. You can also use dynamic port security with SNMP, syslog, or port security aging, to monitor the status and activity of your switch ports and the devices that connect to them. You can also use dynamic port security with 802.1x authentication, to verify the identity of the devices that connect to a port.
