24-Port PoE+ L2 Managed Switch | HSP-IO-24GE4XS-C2PAH

The key specifications are switching capacity, forwarding rate, and Power over Ethernet (PoE) capabilities. The switching capacity determines the maximum data the switch can handle simultaneously, and for a 24-port Gigabit switch, it should be at least 48 Gbps for optimal performance. The forwarding rate measures how quickly the switch can process packets; a rate of at least 35.7 Mpps is ideal. If you plan to power devices like IP phones or access points, consider a switch with sufficient PoE budget and the correct standard (PoE+ or PoE++).

Look for features that give you granular control and enhance network security. VLAN support is essential for segmenting your network into different broadcast domains. For security, prioritize features like Access Control Lists (ACLs) to filter network traffic, 802.1X port security to authenticate connected devices, and DHCP snooping to prevent unauthorized DHCP servers from disrupting your network.

A Layer 2 switch handles traffic at the data link layer, primarily using MAC addresses to forward data within a single network segment or VLAN. A Layer 3 switch has additional functionality to perform routing between different VLANs or subnets, much like a router. If your network is small and doesn't require routing between VLANs, a more affordable Layer 2 switch is sufficient. For larger, more complex networks with multiple subnets, a Layer 3 switch will simplify your network design by handling inter-VLAN routing directly.

A switch works by learning the MAC addresses of all connected devices and storing them in a MAC address table. When a data frame arrives, the switch reads the destination MAC address and forwards the frame only to the corresponding port, ensuring efficient and targeted data delivery.

The most important features of a managed switch are designed to enhance control, security, and performance.

• VLANs (Virtual LANs): Segments your network to isolate traffic and improve security.
• QoS (Quality of Service): Prioritizes specific data traffic, such as VoIP calls and video streams, to prevent lag.
• Network Security: Provides enhanced protection through features like port security and ACLs (Access Control Lists), which prevent unauthorized device access.
• Remote Management: Allows you to configure and troubleshoot the switch from a central location, saving time and effort.
• PoE (Power over Ethernet): Many managed switches can power devices like IP cameras and access points, simplifying installation by using a single cable for both data and power.
