HP 1920 Switch Series
designed for smaller organizations dealing with bandwidth-demanding applications

Features & Benefits:

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

Management

• Simple Web management Allows for easy management of the switch—even by nontechnical 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
• Port mirroring 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 simpler 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 functions; supports events, alarm, history, and statistics group plus a private alarm extension group

Connectivity

• IPv6 – 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 – IPv6 ACL/QoS 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
• IEEE 802.3at Power over Ethernet (PoE+) Provides up to 30 W per port, which allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3afcompliant end device; mitigates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments
• 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
• Auto MDI/MDI-X Adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports

Security

• 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

Performance

• 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 best 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 greater 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 faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP)
• BPDU filtering 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; gratuitous 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 high availability

• Available redundant power supply Provides additional PoE of up to 795 W for high-power applications like PTZ IP cameras, video IP phones; the HP RPS1600 Redundant Power System (JG136A), which is sold separately, is for use with the HP 1920-24G-PoE+ (370W) switch and HP 1920-48G-PoE+ Switch (370W) Switch models only
• 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 an ultra-high bandwidth connection to the network backbone; helps prevent traffic bottlenecks. Note: 8 port models support 4 trunks, 16 and 24 port models support 8 trunks, and 48 port models support 16 trunks

Convergence

• 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
• PoE allocations Support multiple methods (automatic, IEEE 802.3af class, LLDP-MED, or user-specified) to allocate PoE power for more efficient energy savings
• Auto-voice VLAN Recognizes IP phones and automatically assigns voice traffic to dedicated VLAN for IP phones

Additional information

• Green initiative support Provides support for RoHS and WEEE regulations
• Green IT and power Improves energy efficiency through the use of the latest 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
