Efficiency and cost-effectiveness are of utmost importance in the field of networking. Introducing the KSZ8995MAI/FQ, a Layer 2 managed switch that offers excellent integration and is specifically designed to minimize bill of materials (BOM) costs for 10/100Mbps switch systems with a low port count and cost-sensitive requirements. This switch is truly remarkable, as it offers a wide range of features.

Some of these features include VLAN support, quality of service (QoS) prioritization, extensive management capabilities, MIB counters, dual MII interfaces, and CPU control/data interfaces. Welcome to this comprehensive guide where we will explore the key features, benefits, and applications of the KSZ8995MAI/FQ switch. By understanding its capabilities, you will be able to effectively utilize its power for both existing and future fast Ethernet applications.

Key Features

● Integrated Design

The KSZ8995MAI/FQ has five media access control (MAC) units and five fast Ethernet transceivers that all meet the IEEE 802.3u standard. This connection makes setting up your network easier and simplifies things.

● Non-blocking Configuration

A switch fabric that doesn’t block traffic makes sure that data can move between all ports at the same time without causing problems. It’s an important part of keeping a network running well, especially when there’s a lot of data flow.

The KSZ8995MAI has a memory speed of 1.4Gbps, which is very good. This makes sure that the switch can handle large amounts of data without any latency, which is what current applications that use a lot of data need.

● Dual MII setup

The MII-Switch (PHY mode MII  or MAC ) and MII-P5 (PHY mode MII) are both part of the dual MII setup. MII means “Media Independent Interface.” It is a standard interface used to connect Ethernet MAC devices to PHY devices.

Having two MII connections makes it possible for different network parts to work together. It lets you set up the switch in a way that fits the needs of your network. This makes the switch more flexible and able to work with different setups.

● QoS and Rate Limiting

The switch can be set to limit rates from 0Mbps to 100Mbps for both incoming and outgoing connections, with choices for high and low priority. This function makes sure that bandwidth is used well. Flow control or limiting the rate at which packets can be dropped on ingress ports helps handle the traffic.

● MIB Replies

Integrated MIB counters collect fully compliant statistics, and each port has 34 MIB counters. This gives you important information about how your network is running and makes troubleshooting easier.

● Multicast Management

IGMP v1/v2 snooping makes it possible to effectively filter multicast packets, which improves network efficiency and cuts down on traffic that isn’t required.

● Management Interfaces

The switch has serial management interfaces for both SPI slave (full) and MDIO (MII PHY only), making it easy to set up registers.

● Frame Size Flexibility

The switch gives you an “Enable/Disable” choice for frame sizes up to 1916 bytes, so you can use larger frames when you need to.

Understanding these key features of the KSZ8995MAI switch is important if you want to use it to improve network performance, make sure data transfers go smoothly, and make the switch work in a wide range of networking situations.


The KSZ8995MAI/FQ is an excellent choice for various network scenarios, including:

  1. Cost-Sensitive Deployments: The KSZ8995MAI is made for projects with a small number of ports and a limited budget. Its optimized Bill of Materials (BOM) cost makes sure that projects that are sensitive to costs can still use high-quality managed switch features without going over budget.
  2. Network Segmentation: The KSZ8995MAI’s VLAN functionality makes network segmentation effective. This function is essential for managing distinct network segments, improving security, and isolating traffic. Additionally, the switch is adaptable for various network situations since its frame size flexibility supports larger data packets. The main benefits of network segmentation are enhanced security and performance. You can prevent unwanted access and lessen the effects of network outages by placing sensitive devices or departments into different VLANs. As a result, the network becomes more organized and effective, reducing congestion and improving overall network performance.
  3. Quality of Service: QoS becomes essential in situations where bandwidth is constrained or where specific applications need guaranteed bandwidth. For instance, maintaining call quality even during periods of high network usage requires that VoIP conversations be given a higher priority than non-essential web browsing in a corporate setting.
  4. You can design QoS policies that give priority to important apps using the KSZ8995MAI switch. This guarantees a smooth user experience by ensuring that important services like VoIP, video conferencing, or mission-critical data transmission always receive the required bandwidth.
  5. Multicast Optimization: The importance of IGMP (Internet Group Management Protocol) v1/v2 snooping for filtering and enhancing multicast traffic cannot be overstated. The efficiency of the network is increased because it doesn’t swamp the network with pointless multicast packets.

Multicast communication is frequently used in sectors including video streaming, online gaming, and the delivery of multimedia material. Multicast traffic may be used in business settings to simultaneously stream many people with software upgrades or live events.

  1. Fast Ethernet: Both existing and future fast Ethernet applications benefit greatly from the KSZ8995MAI. The switch offers the essential infrastructure to allow fast Ethernet connectivity as businesses continue to seek faster data transmission rates.

The KSZ8995MAI’s high-performance memory bandwidth and effective data handling capabilities provide seamless and uninterrupted data flow in data-intensive environments like video surveillance, high-definition media streaming, or big file transfers.

The importance of the KSZ8995MAI switch in numerous network settings, from cost-conscious installations to guaranteeing optimal performance for crucial applications and data-intensive jobs, is highlighted by understanding these practical applications.


In conclusion, the KSZ8995MAI/FQ stands as a true game-changer in the world of networking, offering a harmonious blend of efficiency, affordability, and a wide array of features. Whether you’re aiming to streamline network operations, optimize segmentation, or ensure the smooth flow of critical applications, this switch is your ultimate solution. With its adaptable design, advanced management capabilities, and support for various media types, it’s a vital tool for any network.
