[pdf] In allow list mode, the network permits access only to devices whose MAC addresses are explicitly approved by the administrator. In allow. I have about ten Cisco switches in my company. I'd like a way to easily apply and centrally manage rules to only allow specific MAC addresses to access any of the ports for any of the VLANs on any of my Cisco switches. Its primary use is to deter the addition by users of “dumb” switches to. Switch Port Security is a Layer 2 security feature available on Cisco switches (and other vendors too) that allows you to control access to a switch port based on the MAC address of devices connected to it. It's mainly used to prevent unauthorized devices from accessing the network. This can be a security risk when users connect.
[pdf] In this layer, the layer 2 switches are installed to distribute the data packets to the addressed group of access devices. When planning an enterprise access network, one of the most common dilemmas is whether to deploy Layer 2 (L2) or Layer 3 (L3) switches. The access layer plays a critical role in connecting end devices—such as computers, printers, IP phones, and wireless access points—to the rest of the enterprise. A Layer-2 switch works at the Data Link layer or Layer 2 of the OSI reference model.
