The NETGEAR M4300-12X12F is a high-performance half-width stackable managed switch engineered for enterprise edge, SMB core, and AV-over-IP deployments requiring high-density 10GbE copper and fiber connectivity in a compact half-width 1U form factor. Delivering 12 x 10GBASE-T RJ-45 ports supporting 100M/1G/10G speeds and 12 x 10GbE SFP+ fiber ports, it provides 480 Gbps of non-blocking switching capacity with a forwarding rate of 357.14 Mpps and sub-microsecond latency for demanding high-bandwidth network environments. Equipped with 32 MB of packet buffer and 128,000 MAC address entries, it handles large-scale Layer 2 and Layer 3 forwarding with policy-based routing and no license required. NSF virtual chassis stacking supports up to 8 units with hitless failover, seamlessly stacking with other M4300 models in spine-and-leaf topologies. SDVoE-ready with IGMP Plus for zero-touch AV-over-IP multicast management. Layer 3 feature set includes OSPF, RIP, VRRP, and PIM. ACL, 802.1X, DHCP Snooping, IP Source Guard, and DoS protection deliver enterprise-class security. Managed via Web GUI, CLI, SNMP v1/v2c/v3, SSH, HTTPS, OpenFlow 1.3, and sFlow.
