PoE Deployment at the Edge Ideal for IDFs in K-12 and SMB networks, horizontal or vertical ring stacking simplifies PoE deployments at the edge while providing distributed 10G uplinks to the core.

Top-of-Rack and Server Installations Two half-width M4300 switches can pair in a single rack for redundant top-of-rack setups. Non-stop switching and routing stacking ensure no single point of failure for connected servers.

Spine and Leaf Topologies M4300 10G models can stack with 1G models to form high-performance spine-and-leaf architectures, reducing oversubscription and enabling line-rate aggregation to the spine.

Performance and Flexibility Serves as a cost-effective 1G access or high-performance 10G distribution layer. Supports mixed 1G/10G stacking for scalable, resilient deployments suitable for WiFi, IP video, and voice applications.

Advanced Software Features Includes Layer 2/3/4 functions, Policy Based Routing, RIP, VRRP, OSPF, and PIM with no licensing fees. Provides security, traffic prioritization, and optimal routing flexibility.

Software Capabilities Granular QoS and security controls at MAC, IP, and transport levels. Supports flexible port-channeling, VLAN/QoS auto-detection, advanced routing, and secure multicast options.

Deployment Flexibility Supports dynamic port state management, robust stacking, link failover without traffic interruption, and compatibility with legacy PVSTP/PVRSTP networks.
