What is the difference between sticky secure MAC addresses and dynamic secure MAC addresses?

What is the difference between sticky secure MAC addresses and dynamic secure MAC addresses?

Dynamic secure MAC addresses – are dynamically learned by the switch and stored in its MAC address table. They are removed from the configuration when the switch restarts. Sticky secure MAC addresses – like Dynamic secure MAC addresses, MACs are learned dynamically but are saved in the running configuration.

Is a MAC address dynamic?

The MAC address is pretty much static. It is integrated into the NIC hardware, but can often be changed by various methods. Each MAC address is usually globally unique but it needs to be only locally unique to work.

What is Aging of MAC address?

The MAC aging time specifies the time before an entry ages and is discarded from the MAC address table. The range is from 0 to 1000000; The default value is 300 seconds. Entering the value 0 disables MAC aging.

What does MAC address sticky mean?

Sticky MAC is a port security feature that dynamically learns MAC addresses on an interface and retains the MAC information in case the Mobility Access Switch reboots.

Why would you need to know a MAC address?

The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Changing a MAC address can be necessary in some cases to keep an Internet connection working.

How do I find a sticky MAC address?

To enable sticky learning, enter the switchport port-security mac-address sticky command. When you enter this command, 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.

What are dynamically learned MAC addresses stored?

When sticky learning is enabled, dynamically learned MAC addresses are stored in the running configuration in RAM and will be lost if the switch is rebooted or an interface goes down.

How do you configure sticky secure MAC addresses?

When you configure sticky secure MAC addresses by using the switchport port-security mac-address sticky mac-address interface configuration command, these addresses are added to the address table and the running configuration.

What does the second command in MAC address sticky do?

A theory for the second command: Is it possible that the switch only adds the address to the table and eventually raises the counted addresses (towards the maximum limit) if it is actually *seen* on the port?

How to disable sticky learning on a Mac?

Also, some additional information: If you disable sticky learning by using the no switchport port-security mac-address sticky interface configuration command or the running configuration is removed, the sticky secure MAC addresses remain part of the running configuration but are removed from the address table.

How to remove sticky option from MAC address table?

When you configure sticky option in a port-secure, the mac address is added to the Mac Address Table as Static. In order to remove this address from the Mac Address you can use the global config command
