The series has five models: the HP V1910-16G, V1910-24G, V1910-48G, V1910-24G-PoE (170 W), and V1910-24G-PoE (365 W) Switch. Each V1910 switch has 10/100/1000 ports and an additional four true Gigabit SFP ports. These smart-managed switches deliver advanced features for environments not requiring centralized administration and allow network operation to be enhanced using an intuitive Web-based management interface. Advanced features include Layer 3 static routing, access control lists for enhanced security, auto-voice VLAN, QoS traffic prioritization, LLDP, Spanning Tree Protocols, and Power over Ethernet models. All switches are supported by a 3-year warranty.<br><br><b>Features</b><br><br>- IEEE 802.1p prioritization: delivers data to devices based on the priority and type of traffic<br>- Traffic prioritization (IEEE 802.1p): allows real-time traffic classification mapped to four hardware queues per port<br>- Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers<br>- 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<br>- Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums<br>- Simple Web management: intuitive Web GUI allows for easy management of device by even nontechnical users<br>- Single IP management: enables management of up to 32 V1910 devices using a single Web interface; simplifies management of multiple devices<br>- Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS<br>- SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices<br>- Logging: provides local and remote logging of events via SNMP (v2c and v3) and syslog; provides log throttling and log filtering to reduce the number of log events generated<br>- Auto-MDI/MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports<br>- IEEE 802.3X flow control: provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node<br>- * IEEE 802.3af Power over Ethernet (PoE) ready: PWR models able to provide up to 15.4 W per port to power standards-compliant IP phones, wireless LAN access points, Web cameras, and more<br>- Packet storm protection: protects against broadcast, multicast, or unicast storms with user-defined thresholds<br>- Jumbo Frames: allow high-performance remote backup, server links, and disaster-recovery services<br>- Half-/Full-duplex autonegotiating capability on every port: doubles the throughput of every port<br>- Advanced QoS and traffic shaping: provides traffic prioritization using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS)with Differentiated Services Code Point (DSCP) and ingress/egress rate shaping to help ensure that critical time-sensitive traffic like voice receives the priority needed for qualitycommunications<br>- VLANs: segment the network by grouping users based on their data or traffic exchangerequirements; help ensure improved use of available bandwidth as traffic flow is directedaccording to the needs of the business<br>- Link aggregation (trunking): groups together up to 8 ports automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the networkbackbone; helps prevent traffic bottlenecks<br>- Selectable queue configurations: increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications<br>- IEEE 802.1w Rapid Convergence Spanning Tree Protocol: increases network uptime through faster recovery from failed links<br>- IEEE 802.1D Spanning Tree Protocol (STP): provides redundant links while preventing network loops<br>- IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees<br>- Link aggregation (trunking): groups together up to 8 ports automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the networkbackbone; helps prevent traffic bottlenecks<br>- Redundant Power Supply (365 PWR model only): DC power supply provides additional PoE budget of up to 740 W for high power applications like Gigabit IntelliJack switches<br>- VLAN support and tagging: supports IEEE 802.1Q (4,094 VLAN IDs) and 256 VLANs simultaneously<br>- Jumbo packet support: supports up to 9220-byte frame size to improve performance of large data transfers<br>- Spanning Tree: fully supports standard IEEE 802.1D Spanning Tree Protocol, IEEE 802.1w Rapid Spanning Tree Protocol for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol<br>- Port mirroring: duplicates port traffic (ingress and egress) to a local or remote monitoring port<br>- BPDU tunneling: transmits Spanning Tree Protocol BPDUs transparently, allowing correct tree calculations across service providers, WANs, or MANs<br>- User Datagram Protocol (UDP) helper function: allows UDP broadcasts to be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevents server spoofing for UDP services such as DHCP<br>- 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<br><br>
