Thi method pomaga zapobiec nieautoryzowaniu access and protectives sensitiva data from potential controls.

Adresaci MAC

A MAC adresaci i unikalne identyfikatory is assigned to each network interface card (NIC) in a device.

How MAC Adresaci Filtering Works

MAC adresaci filtering involves creating a list of authorized MAC adresaci on a network device, such as a router or switch. Only devices with MAC adresaci on this list are permitted to connect. This process can be set up in two ways:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Whitelist: Xi1; Xi1; FLT: 1 Xi3; Xi3; Only listed MAC addisses can accords the network.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Blacklist: Xi1; Xi1; FLT: 1 Xi3; Xi3; Listed MAC addisses are bloked frem connecting.
