What is MAC in itil?
Moves, adds and changes (MAC) is a set of tasks that IT teams regularly perform to keep computing equipment up-to-date and aligned with user requirements.
MAC move allows 802.1X or MAC authenticated users to move between ports on a device. For example, if an authenticated 802.1X user moves to another 802.1X-enabled port on the device, the authentication session is deleted from the first port. The user is reauthenticated on the new port.
Moves, adds and changes (MAC) is the general term for the routine work performed on computer equipment in an enterprise, including installations, relocations and upgrades.

Sets the maximum amount of time a MAC address remains in the MAC address table. When this time expires, the MAC address is removed. The no form of this command resets the MAC aging timer to the default value (300 seconds).
Persistent MAC learning or sticky MAC is a port security feature where dynamically learned MAC addresses are retained when a switch or interface comes back online.
MAC Address Aging
The expected MAC address expiration timer is between 300 and 600 seconds, depending on the number of MAC addresses learned. You can configure the amount of time an entry remains in the MAC table. You can also configure MAC aging time in interface configuration mode or in VLAN configuration mode.
The full form of IMAC is internet Macintosh.

How Many Macs Exist? Currently, there are 12 Medicare Part A and B MACs that assist with Original Medicare (Medicare Parts A and B). Four of these MACs also process home health and hospice claims in addition to their typical Medicare Part A and Part B claims. There are also four durable medical equipment (DME) MACs.
A Medicare Administrative Contractor (MAC) is a private health care insurer that has been awarded a geographic jurisdiction to process Medicare Part A and Part B (A/B) medical claims or Durable Medical Equipment (DME) claims for Medicare Fee-For-Service (FFS) beneficiaries.

Why is aging time important?
From a public health perspective, aging is also the critical risk factor for a variety of human pathologies, including neurodegenerative diseases such as Alzheimer's, many forms of cancer and metabolic disease/type II diabetes, which have become much more prevalent in the elderly.
The MAC address table is where the switch stores information about the other Ethernet interfaces to which it is connected on a network. The table enables the switch to send outgoing data (Ethernet frames) on the specific port required to reach its destination, instead of broadcasting the data on all ports (flooding).
A Static MAC address is one that has been manualy input (typed via a command) into the CAM or MAC address table. A dynamic MAC address is one that has been learned via an arp request. For example if a switch learns the MAC address from another device then it has dynamically sourced the MAC address.
Persistent randomization
Android generates a persistent randomized MAC address based on the parameters of the network profile including SSID, security type, or FQDN (for Passpoint networks). This MAC address remains the same until factory reset.
To delete a sticky secure MAC addresses from the address table, use the no switchport port-security sticky mac-address mac_address command. To delete all the sticky addresses on an interface or a VLAN, use the no switchport port-security sticky interface interface-id command.
