HP 3100 EI series switches are Layer 2 Ethernet switches designed for enterprise networks demanding high security and intelligence. They provide 10/100 Mbps downlink and 1000 Mbps uplink Ethernet ports, and serve as access devices for 100 Mbps-to-desktop applications in enterprise networks.

In metropolitan area networks or various industry networks, they connect end users or aggregate client devices with 10/100 Mbps connections, converging at a higher-capacity switch with 1000 Mbps interfaces. Features include advanced Quality of Service (QoS), rate limiting, QinQ (virtual LAN [VLAN]/VPN), SSHv2, Multicast VLAN Registration (MVR), Virtual Cable Tester (VCT), HGMP V2, GARP VLAN Registration Protocol (GVRP), access control list (ACL), media access control (MAC)-IP-port binding, Endpoint Admission Defense, voice and protocol-based VLAN, Internet Group Management Protocol snooping, and Power over Ethernet (PoE).        

Funkce

Quality of Service (QoS)

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 per-port or per-VLAN basis
Powerful QoS feature: supports the following congestion actions: strict priority queuing (SP), weighted round robin (WRR) queuing, and SP+WRR
Traffic policing: supports Committed Access Rate (CAR) and line rate

Management

Friendly port names: allow assignment of descriptive names to ports
Remote configuration and management: is available through a secure Web browser or a 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 HWTACACS 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

IPv6 (on v2 products): Telnet v6: to allow IPv6 management. DNSv6 Client: for IPv6 host management. SNMPv6: for IPv6 switch management. DHCPv6 Client: for automatic IPv6 address configuration of a switch.
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
Flow control: provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations
Gigabit Ethernet uplinks: are dual-personality ports for either 10/100/1000 or mini-GBIC SFP connectivity for increased connectivity flexibility
IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras

Performance

Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM based) helps provide high levels of security and ease of administration without impacting network performance
Gigabit Ethernet interface: provides a connection to the network that eliminates the network as a bottleneck
