HPE JE074A Network Switch Networking

Overview
The HP 5120 SI Switch Series comprises intelligent, fully managed Gigabit Ethernet switches that provide high performance, high port density, and simplified installation to improve the value of your network infrastructure investment. The 5120 SI series is enhanced for 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 more effective throughput and the bandwidth necessary for mission-critical data and high-speed communications. As part of their comprehensive security control, 5120 SI switches 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 network broadcast traffic

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
