managed network switch

Enterprises recognize that all of the new technologies they want to deploy – IoT, edge computing, serverless, containers, hybrid cloud, and AI – require a robust, flexible, secure, self-healing, software-driven network.

And the industry has responded with fresh new approaches such as software-defined networking (SDN), SD-WAN, hyperconverged infrastructure (HCI) and intent-based networking.

NETGEAR Fully Managed Switches connect end-users, critical services, servers and storage across flexible core, distribution and access layers. Our Managed Infrastructure combines latest advances in hardware and software engineering for higher flexibility, lower complexity and stronger investment protection. A single-pane-of-glass management platform – NMS300 – increases overall operational efficiency.

Managed Ethernet switches have more capability than unmanaged switches, but they also require a skilled administrator or engineer to make the most of them. A managed switch enables you to have better control of your network and all the data frames moving through it. Unmanaged switches, on the other hand, enable connected devices to communicate with one another in their most basic form.

Unmanaged switches do maintain a media access control (MAC) address table, however. This table keeps track of dynamically learned MAC addresses and the corresponding switch port on which the MAC address was learned. The inclusion of a MAC address table means unmanaged switches do offer a separate, per-port collision domain. This is a key differentiator between an unmanaged Ethernet switch and an Ethernet hub.

Managed Ethernet switches
A major difference between managed and unmanaged switches is control. A managed switch lets you adjust each port on the switch to any setting you desire, enabling you to monitor and configure your network in many ways. It also provides greater control over how data travels over the network and who has access to it. Managed switches generally offer Simple Network Management Protocol, which enables you to monitor the status of the switch and individual switch ports and gives you statistics like traffic throughput, network errors and port status.

Features available on managed switches may vary among manufacturers and models, but they often include the following:

Below, we compare the differences between managed and unmanaged switches.

Unmanaged Ethernet switches
Unmanaged switches use autonegotiated ports to determine parameters such as the data rate and whether to use half-duplex or full-duplex mode. Additionally, unmanaged switches have no concept of virtual LANs (VLANs). Thus, all devices belong to the same broadcast domain.
