What are some 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.
• SDN compatibility and AI-driven traffic management for automation and monitoring .
