HP V1910-24G 3CRBSG2893 Data Sheet

3

• 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 quality communications

• VLANs: segment the network by grouping users

based on their data or traffic exchange
requirements; help ensure improved use of available
bandwidth as traffic flow is directed according to
the needs of the business

• 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 network
backbone; helps prevent traffic bottlenecks

• Selectable queue configurations: increase

performance by selecting the number of queues and
associated memory buffering that best meet the
requirements of your network applications

• Spanning Tree Protocol (STP/RSTP/MSTP):

improves network compatibility, scalability, and
availability

• IGMP snooping: multicast filtering improves

network performance, instead of flooding traffic to
all ports

• Unique voice features: automatic assignment of

voice traffic separates VLANs (“auto-voice VLAN”);
advanced voice QoS, traffic shaping, multicast
filtering, and PoE support delivers the support
necessary for quality voice communications

• Fiber uplink: provides greater distance

connectivity using Gigabit fiber uplinks

• PoE support (PWR model only): provides

power for IP phones, wireless LAN access points,
and other IEEE 802.3af-compliant devices over the
same cable used for data; lowers total cost of
ownership because there is no need to run
additional electrical wiring; supports prestandard
PoE plus, allowing the switch to deliver up to 30 W
of power

Resiliency and high availability

• IEEE 802.1w Rapid Convergence Spanning

Tree Protocol: increases network uptime through
faster recovery from failed links

• IEEE 802.1D Spanning Tree Protocol (STP):

provides redundant links while preventing network
loops

• IEEE 802.1s Multiple Spanning Tree: provides

high link availability in multiple VLAN environments
by allowing multiple spanning trees

• 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 network
backbone; helps prevent traffic bottlenecks

• 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

Layer 2 switching

• VLAN support and tagging: supports IEEE

802.1Q (4,094 VLAN IDs) and 256 VLANs
simultaneously

• Jumbo packet support: supports up to

9220-byte frame size to improve performance of
large data transfers

• 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

• Port mirroring: duplicates port traffic (ingress

and egress) to a local or remote monitoring port

• BPDU tunneling: transmits Spanning Tree

Protocol BPDUs transparently, allowing correct tree
calculations across service providers, WANs, or
MANs

• Spanning Tree/MSTP, RSTP, and STP Root

Guard: prevent network loops

• 8K MAC addresses: allows multiple Layer 2

devices to be networked through the switch

Layer 3 services

• 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

• 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
