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
Powerful QoS feature: supports the following congestion actions: strict priority (SP) queuing, SDWRR, and SP+SDWRR
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 per-port basis

Management

Friendly port names: allow assignment of descriptive names to ports
Remote configuration and management: is available through a secure Web browser or a command-line interface (CLI)
Manager and operator privilege levels: enable read-only (operator) and read/write (manager) access on CLI and Web browser management interfaces
Command authorization: leverages RADIUS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail
Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS

Connectivity

Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Flow control: using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations
Jumbo packet support: supports up to 10k byte frame size to improve performance of large data transfers
High-density port connectivity: provides up to 48 fixed 10/100/1000BASE-T ports in an entry-level static Layer 3 switch
Ethernet OAM: provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network convergence times

Performance

Nonblocking architecture: up to 104 Gbps nonblocking switching fabric provides wire-speed switching with up to 77.4 million pps throughput
Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM-based) helps ensure high levels of security and ease of administration without impacting network performance
