Layer 2 IP network switches use VLANs to segment a local network and forward Ethernet traffic within each VLAN, with features such as IGMP snooping helping manage multicast traffic without routing between VLANs. Layer 3 IP network switches add routing functions, including inter-VLAN routing and, on supported models, static, policy-based, dynamic, or multicast routing, so traffic can move between VLANs and multicast streams can follow a more controlled path.

Choose a port count by adding the ports required for cameras, access points, phones, AV devices, and other wired endpoints, then allow room for future expansion. Size the Power over Ethernet (PoE) capacity by totaling the power needs of connected devices, and select uplink speeds based on network traffic, with higher-speed 10G SFP+ uplinks supporting demanding video-over-IP, AV, and multi-switch deployments.

Look for a managed IP network switch with sufficient port capacity, multigigabit or 10G uplinks, and Layer 2 or Layer 3 features such as VLANs, IGMP, and multicast routing for AV over IP and video traffic. If the switch will power cameras, access points, or other endpoints, choose a model with the appropriate Power over Ethernet (PoE) type and power budget, along with monitoring or remote-management features that support troubleshooting.

IP network switches with managed Layer 2 or Layer 3 control, plug-and-play setup options, and rack-mount, desktop, or wall-mount designs can simplify installation and configuration. Built-in monitoring through a network controller or remote-management platform, per-port Power over Ethernet (PoE) controls, and SFP or SFP+ uplink ports can support ongoing maintenance and future network expansion.
