A5120-48G SI SWITCH IN

Overview
The HP A5120G SI Switch Series are intelligent, manageable Gigabit Ethernet switches that provide high performance, high-density port access, and simplified installation to maximize the value of your network infrastructure investment. They are typically deployed at the access layer in enterprise networks that require Gigabit Ethernet to the desktop or at the distribution layer in metropolitan area networks (MANs). Wire-speed forwarding delivers optimal throughput and the bandwidth necessary for mission-critical data and high-speed communications. As part of their comprehensive security control, they employ 802.1X authentication to identify users who attempt to access the network. These switches are highly reliable, providing redundancy while eliminating loops in the network. They also offer a range of management protocols to simplify network administration.

Features
Quality of Service (QoS)

⁍ Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network


Management

⁍ Friendly port names: allow assignment of descriptive names to ports


Connectivity

⁍ Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports


Performance

⁍ Nonblocking architecture: up to 104 Gbps nonblocking switching fabric provides wire-speed switching with up to 77.4 million pps throughput


Resiliency and high availability

⁍ Separate data and control paths: increases security and performance


Layer 2 switching

⁍ 8K MAC address table: provides access to many Layer 2 devices


Layer 3 services

⁍ Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses
