Recommendations for good core switches

Top recommended core switches include Cisco Catalyst 9300L, Cisco C9500-16X-A, HPE Aruba CX 8360 v2, Arista 7500 Series, and NETGEAR 48-port managed switches, offering high performance, scalability, and advanced security.

Key Considerations for Choosing Core Switches

Core switches form the backbone of enterprise networks, connecting aggregation layers and ensuring high-speed, reliable data forwarding. When selecting a core switch, consider: Layer 3 capabilities for routing and network segmentation. High port density and support for 10G/40G/100G uplinks.

Redundancy with dual power supplies and failover features. PoE/PoE+ support for powering devices like access points and IP phones. Advanced security including MACsec, ACLs, and TrustSec.

SD

N compatibility and AI-driven traffic management for automation and monitoring.
