L3 basic switching rj-45 ethernet ports quantity: 24 mac address table: 16000 entries switching capacity: 48 gbit s 1u rack mounting stackable the hp 5120 ei switch series is comprised of gigabit ethernet switches that support static layer 3 routing, diversified services, and ipv6 forwarding, as well as provide up to four 10-gigabit ethernet 10 gbe extended interfaces. Unique intelligent resilient framework irf technology creates a virtual fabric by managing several switches as one logical device, which increases network resilience, performance, and availability while reducing operational complexity. These switches provide gigabit ethernet access and can be used at the edge of a network or to connect server clusters in data centers. High scalability provides investment protection with two expansion slots, each of which can support two-port 10 gbe expansion modules. High availability, simplified management, and comprehensive security control policies are among the key features that distinguish this series.- Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic. Advanced classifier-based qos: classifies traffic using multiple match criteria based on layer 2, 3, and 4 information applies qos policies such as setting priority level and rate limit to selected traffic on a port, vlan, or whole switch. Powerful qos feature: supports the following congestion actions: strict priority sp queuing, weighted round robin wrr , ...
