A core switch is a switch placed in the core layer (backbone part of the network). It is located at the top layer of the three-layer network architecture, which is equivalent to the senior management of the company. Its main role is to quickly forward the data from the aggregation layer and provide a fast and reliable network architecture through high-speed data forwarding.
A core switch is a Layer 3 switch with network management functions. Generally speaking, the core switch has a large number of ports and high bandwidth. Compared with the access switch and aggregation switch, the core switch has higher reliability, redundancy, throughput, and relatively low latency. GXCOM can provide the 24 port L3 managed poe-switch

When choosing a core PoE switch, the following aspects should be considered:
Port Configuration
● Port Number: Estimate the number of devices to be connected, such as IP cameras, VoIP phones, and wireless access points, and choose a switch with sufficient ports to meet current and future expansion needs.
● Port Types: Ensure the switch has the appropriate combination of RJ45 ports for Ethernet connections and SFP/SFP+ ports for fiber optic connections to integrate with existing network infrastructure.
● Port Speeds: Select switches with multi-speed ports, like 100M/1G/2.5G/5G/10G auto-sensing ports, to support high-bandwidth devices and provide flexibility for network upgrades.
PoE Standards and Power
● PoE Standards: Check if the switch supports the common PoE standards, such as IEEE 802.3af (15.4W per port) or IEEE 802.3at (30W per port). Choose according to the power requirements of the connected devices.
● Single Port Power: Ensure the single port power of the switch can meet the highest power requirement of any device connected to it.
● Total Power Budget: Calculate the total power consumption of all connected PoE devices and select a switch with a sufficient total power budget to avoid overloading.
Network Performance
● Throughput and Bandwidth: The core PoE switch should have high throughput to handle large amounts of data traffic. Consider switches with higher gigabit or even 10-gigabit ports for better performance.
● Forwarding Capacity: Look for switches with advanced forwarding technologies, such as cut-through or store-and-forward, to minimize latency and ensure smooth data transmission.
● Quality of Service (QoS): QoS features help prioritize traffic, ensuring critical applications like video surveillance or VoIP calls receive sufficient bandwidth and low latency.
Management and Security Features
● Management Capabilities: Managed PoE switches allow for remote configuration, monitoring, and management, enabling you to control port settings, VLANs, and other parameters easily.
● Security Features: Consider features like access control lists (ACLs), port security, and DHCP snooping to enhance network security and prevent unauthorized access.
Reliability and Redundancy
● Redundant Power Supplies: To ensure continuous operation, choose a switch with redundant power supplies that can provide backup power in case of a power failure.
● Link Aggregation: Link aggregation allows you to combine multiple physical links into a single logical link, providing redundancy and increased bandwidth.
Brand and Support
● Reputable Brand: Select products from well-known and reliable brands with a good track record in the networking industry to ensure product quality and after-sales support.
● Warranty and Support: Check the warranty period and the availability of technical support, including online resources, customer service, and firmware updates.
