The 1920 8-Gigabit Port Layer 3 Switch from HP features 8 RJ-45, auto-negotiating 10/100/1000 ports, and two SFP 1000 Mb/s ports and supports rackmounting or desktop operations. Its customizable features include basic Layer 2 features like VLANs and link aggregation, as well as advanced features such as Layer 3 static-routing, IPv6, ACLs, and Spanning Tree Protocols. It provides an easy-to-administer solution for small businesses.


Simple Web Management
Allows for easy management of the switch, even by non-technical users, through an intuitive Web GUI; supports HTTP and HTTP Secure (HTTPS)
Single IP Management
Enables management of up to 32 HP 1920 switches using a single Web interface, simplifies management of multiple devices
SNMPv1, v2c, and v3
Facilitate management of the switch, as the device can be discovered and monitored from an SNMP management station
Complete Session Logging
Provides detailed information for problem-identification and resolution
Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
Dual Flash Images
Provide independent primary and secondary operating system files for backup while upgrading
Management Security
Restricts access to critical configuration commands; offers multiple privilege levels with password protection; ACLs provide TELNET and SNMP access; local and remote syslog capabilities allow logging of all access
Network Time Protocol (NTP)
Synchronizes timekeeping among distributed time servers and clients; keeps timekeeping consistent among all clock-dependent devices within the network so that the devices can provide diverse applications based on the consistent time
Limited CLI
Enables users to quickly deploy and troubleshoot devices in the network
Default DHCP Client Mode
Allows the switch to be directly connected to a network, enabling plug-and-play operation; in absence of a DHCP server on the network, the switch will fall back to a unique static address determined by the switch's MAC address
FTP, TFTP, and SFTP Support
Offer different mechanisms for configuration updates; FTP allows bidirectional transfers over a TCP/IP network; trivial FTP (TFTP) is a simple method using User Datagram Protocol (UDP); Secure File Transfer Protocol (SFTP) runs over an SSH tunnel to provide additional security
Remote Monitoring (RMON)
Uses standard SNMP to monitor essential network function

Quality of Service (QoS)

Traffic Prioritization
Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification; packets are mapped to eight hardware queues for more effective throughput
IEEE 802.1p/Q VLAN Tagging
Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q
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
Broadcast Control
Allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic
Rate Limiting
Sets per-port ingress enforced maximums and per-port, per-queue minimums
Class of Service (CoS)
Sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
Powerful QoS Feature
Supports the following congestion actions: strict priority queuing (SP), Weighted Round Robin (WRR) queuing, and SP+WRR


IPv6 Host
Enables switches to be managed and deployed at the IPv6 network's edge
IPv6 Routing
Supports IPv6 static routes
MLD Snooping
Forwards IPv6 multicast traffic to the appropriate interface, preventing traffic-flooding
Supports ACL and QoS for IPv6 network traffic
IEEE 802.3X Flow Control
Provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node
Cable Diagnostics
Detects cable issues remotely using a browser-based tool
Flow Control
Provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations
Adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports


Advanced Access Control Lists (ACLs)
Enables network traffic-filtering and enhances network control using MAC- and IP-based ACLs; time-based ACLs allow for greater flexibility with managing network access
IEEE 802.1X and RADIUS Network Logins
Controls port-based access for authentication and accountability
Secure Sockets Layer (SSL)
Encrypts all HTTP traffic, allowing safe access to the browser-based management GUI in the switch
Port Isolation
The port isolation feature isolates Layer 2 traffic for data privacy and security without using VLANs. This feature can also be used to isolate the hosts in a VLAN from one another
Port Security
Combines and extends IEEE 802.1X and MAC authentication to provide MAC-based network access control
ARP Attack Protection
The ARP detection feature enables access devices to block ARP packets from unauthorized clients to prevent user spoofing and gateway spoofing attacks
Automatic VLAN Assignment
Assigns users automatically to the appropriate VLAN based on their identity, location, and time of day
STP BPDU Port Protection
Blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
STP Root Guard
Protects the root bridge from malicious attacks or configuration mistakes
Automatic Denial-of-Service Protection
Monitors for malicious attacks and protects the network by blocking the attacks
Management Password
Provides security so that only authorized access to the Web browser interface is allowed


Half and full-duplex, auto-negotiating capability on every port doubles the throughput of every port
Selectable Queue Configurations
Allows for increased performance by selecting the number of queues and associated memory-buffering that meet the requirements of the network applications
IGMP Snooping
Improves network performance through multicast-filtering, instead of flooding traffic on all ports
Fiber Uplink
Provides great distance connectivity using Gigabit Ethernet fiber uplinks

Layer 2 Switching

Spanning Tree Protocol (STP)
Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for fast convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP)
Drops BPDU packets when STP is enabled globally but disabled on a specific port
Jumbo Frame Support
Supports up to 10 kilobyte frame size to improve the performance of large data transfers
VLAN Support and Tagging
Support IEEE 802.1Q with 4,094 simultaneous VLAN IDs

Layer 3 Services

Address Resolution Protocol (ARP)
Determines the MAC address of another IP host in the same subnet; supports static ARPs; ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
DHCP Relay
Simplifies management of DHCP addresses in networks with multiple subnets

Layer 3 Routing

Static IPv4/IPv6 Routing
Provides basic-routing (supporting up to 32 static routes and 8 virtual VLAN interfaces); allows manual routing configuration

Resiliency and Availability

Link Aggregation
Groups together multiple ports (up to a maximum of eight ports per trunk) automatically using Link Aggregation Control Protocol (LACP), or manually to form a high bandwidth connection to the network backbone and helps prevent traffic bottlenecks. 1


LLDP-MED (Media Endpoint Discovery)
Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to configure network devices such as IP phones automatically
Auto-Voice VLAN
Recognizes IP phones and automatically assigns voice traffic to dedicated VLAN for IP phones

Other Features

Green Initiative Support
Provides support for RoHS and WEEE regulations
Green IT and Power
Improves energy efficiency through the use of the advances in silicon development; shuts off unused ports and utilizes variable-speed fans, reducing energy costs
Energy Efficient Ethernet
Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity
