Specifications of a 24-port core switch

A 24-port core switch typically offers 24 Gigabit or higher ports, multiple uplink options, high throughput, stacking capabilities, and advanced management features suitable for enterprise networks.Cisco Catalyst 9300 Series (C9300-24T-E)Ports: 24 x 1G Ethernet (data only) with support for Multigigabit in some models .Uplinks: Flexible modular uplinks supporting 1G, 10G, 25G, 40G, and 100G .Stacking: Up to 1 Tbps StackWise-1T bandwidth, supporting mixed stacking with other Catalyst 9300/9300X switches .Throughput: 480 Gbps switching capacity .Power: Supports StackPower for power resiliency; some models offer up to 90W UPOE+ per port .Management: On-premises, virtual, or cloud-based management; supports Cisco DNA Center and advanced security features .Additional Features: Optimized for high-density 802.11ac Wave2, x86 CPU architecture for hosting containers and third-party applications .Cisco Catalyst 9500 Series (Core-Focused)Ports: 24 fixed ports with options for 10G, 25G, 40G, 50G, 100G, 200G, or 400G Ethernet depending on model .Uplinks: Nonblocking SFP-56 and QSFP-DD ports for high-capacity uplinks .Throughput: Up to 12.8 Tbps full-duplex switching capacity .Stacking/Virtualization: Supports Cisco StackWise Virtual for high availability and network virtualization .Management: Cisco Catalyst Center or Meraki cloud monitoring; advanced routing, MPLS, VPN, and SD-Access capabilities .High Availability: Redundant Platinum-rated power supplies, fans, and NSF/SSO support .UniFi 24-Port SwitchPorts: 24 x RJ45 Gigabit Ethernet ports .Uplinks: 2 x SFP ports for 1G uplinks; higher-end models may include SFP+ for 10G uplinks .Throughput: 26 Gbps non-blocking total throughput .Management: Managed via UniFi Controller software with centralized GUI for multiple sites .Features: Line-rate forwarding, VLAN support, QoS, and graphical monitoring .D-Link DGS-3024Ports: 24 x 10/100/1000BASE-T copper ports + 4 combo SFP for fiber uplinks .Throughput: Full Gigabit switching on all ports .Management: Layer 2 managed switch with VLAN, port trunking, priority queues, 802.1x access control, and broadcast storm control .Power: Redundant power supply support .Features: Auto MDI/MDIX, flexible fiber backbone attachment via SFP modules .Key Considerations for a 24-Port Core SwitchPort Speed and Type: Core switches often require 10G or higher uplinks; 1G may suffice for smaller networks.Stacking and Redundancy: Look for StackWise or virtual stacking for high availability.Throughput and Non-Blocking Capacity: Ensure the switch can handle full line-rate traffic on all ports.Power over Ethernet (PoE/UPOE): Important if powering devices like access points or IP phones.Management and Security: Advanced features like VLANs, QoS, SD-Access, and cloud management enhance network control.Future Scalability: Consider modular uplinks and compatibility with higher-speed switches for growth.These specifications provide a comprehensive overview of 24-port core switches suitable for enterprise or campus networks, highlighting options from Cisco, UniFi, and D-Link.
