ways to configure a network interface for 802.1x mac sierra

If you save the sticky secure MAC addresses in the configuration file, when the switch restarts, the interface does not need to relearn these addresses. The sticky secure MAC addresses do not automatically become part of the configuration file, which is the startup configuration used each time the switch restarts. All sticky secure MAC addresses are added to the running configuration. After you’ve enabled sticky learning, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses. You can configure an interface to convert the dynamic MAC addresses to sticky secure MAC addresses and to add them to the running configuration by enabling sticky learning. If these addresses are saved in the configuration file, when the switch restarts, the interface does not need to dynamically reconfigure them. These can be dynamically learned or manually configured, stored in the address table, and added to the running configuration. These are dynamically configured, stored only in the address table, and removed when the switch restarts. These are manually configured by using the switchport port-security mac-address mac-address interface configuration command, stored in the address table, and added to the switch running configuration. Secure MAC Addresses Types of secure MAC Addresses

A secure port and static MAC address configuration are mutually exclusive.

If you try to change an 802.1X-enabled port to a secure port, an error message appears, and the security settings are not changed. If you try to enable 802.1X on a secure port, an error message appears, and 802.1X is not enabled.

A secure port cannot be an 802.1X port.A secure port cannot belong to an EtherChannel port-channel interface.A secure port cannot be a destination port for Switch Port Analyzer (SPAN).Enable/Disable to send a SNMP Trap if there is any violation detected.This feature, remove and add PCs on a secure port without manually deleting the existing secure MAC addresses while still limiting the number of secure addresses on a port. Set aging time and type for secure MAC Addresses.The port inserts MAC Address dynamically to the configuration when a new device has plugged in until it reach the maximum allowed MAC Addresses. Restrict a number of MAC Addresses on a certain port.Devices that have other MAC Addresses can’t connect to the network. Restrict only specified MAC Addresses on a certain port.If a user attempts to connect a new device (E.g, laptop) on the port which has already enabled port security and the port has reach the maximum allow MAC Addresses, the device won’t have access to the network until an administrator changes the configuration on the swtich. So only defined MAC Addresses can have accessed to the network. Port Security is a feature on Cisco’s products that help you to protect unauthorized access to the network by restrict MAC Addresses that can be connected to interface on the switch. In this post, I’ll talk about a feature on Cisco’s products which is “Port Security”. Thus, limiting the potential damage from emerging security threats and risks. This will allow only certain devices such as PC, laptop, PDA, etc.

It is a challenge task for network administrators to harden the network to be secure as possible.One way to enhance network security, you can implement Network Access Control (NAC) or Network Admission Control. I’m using the word ‘decrease’ mean that there is no way to completely secure the network without any threat and risk. Hence, reduce the loss of damage from them. Having a strong network security means you have decreased a success chance of hackers or malicious people that try to break into your network. In every organization or even a home that has a network, security is one of the important issue.
