Access Switch MAC Restriction
MAC filtering is a network access control method where a router or switch allows or blocks devices based on their MAC (Media Access Control) address. When a device tries to join a network, the router or access point checks the device's MAC address against the configured filtering. UniFi makes it easy to employ a MAC-based access control list in order to restrict unfamiliar devices from accessing your network. Navigate to. Yes, ISE is a radius and tacacs server and it is expensive. Learn how to improve the security and manageability of your local network.

Broadband Management Switch Port Aggregation
Link aggregation, also known as port aggregation or NIC teaming, is a technique used in layer 2 and layer 3 network switches to combine multiple physical links into a single logical link. This logical link provides increased bandwidth, redundancy, and load balancing. Port aggregation is useful for implementing load balancing and provides a redundant link. Link aggregation is a term used to describe various implementations and underlying technologies. While there are many approaches, this article aims to highlight the. Switch-to-Switch Aggregation: This is useful in scenarios where you need to interconnect multiple switches to increase the bandwidth available between them and ensure network redundancy. It helps in managing higher traffic loads between switches. APs and wireless clients can continue to send and receive data.

How to perform aggregation using a switch
Configuring port aggregation on a UniFi switch is straightforward using the UniFi Network Controller (or UniFi OS Console). This arrangement increases throughput beyond what a single relationship could sustain, offers redundancy in case one of the links. An aggregate switch is a high-capacity network switch that consolidates connections from multiple access switches, acting as a central point for managing network traffic and providing enhanced bandwidth capabilities. It essentially acts as a traffic cop.
