HPE OfficeConnect 1950 48G 2SFP+ 2XGT Switch JG961A

Management

·  Four-high true stacking

Simplifies administration of multiple devices. Create a single logical managed unit with up to four HPE OfficeConnect 1950 switches. Balance connections across multiple units with standard Link Aggregation (LACP) for enhanced network resiliency. Stack using affordable Cat 6a, or long distance fiber, or localized DAC cables. Stacked units can be co-located or separated physically.

·  Intuitive Web browser-based management Allows for easy customization of the switch even by non-technical users.

·  Secure Web-management sessions with HTTPS / SSL

Encrypts and otherwise protects management sessions through HTTP Secure (HTTPS). Prevents snooping of sensitive management information such as passwords.

·  SNMPv1, v2c, and v3

Facilitates remote 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

·  Dual flash images Provides independent primary and secondary operating system files for backup while upgrading

·  Port mirroring Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring

·  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

·  IEEE 802.1AB Link Layer Discovery Protocol (LLDP)

Advertises and receives management information from adjacent devices on a network, facilitating easy mapping by network management applications

·  Limited Command Line Interface (CLI)

Facilitates in the deployment and initial configuration of the unit. Supports troubleshooting actions as well.

·  RMON Provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events

·  Default DHCP client modes

Simplifies device deployment. Connect a new out-of-the box switch to a network with a DHCP server and the device will obtain its IP address automatically with plug-and-play operation. In the absence of a DHCP server, the switch will fall-back to a unique static address determined by the switch's MAC address.

·  Cable diagnostic tool Use to remotely detect cable issues with cables attached to the switch.

Quality of Service (QoS)

• 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
• Traffic prioritization

Makes it possible to prioritize important and/or time-sensitive traffic ahead of less important traffic. Use with VoIP or video to optimize its performance on the network. Recognizes both IEEE 802.1p and DSCP prioritization tagging. Packets are mapped to four hardware queues for more effective throughput.

• Powerful QoS feature

Supports the following congestion actions: strict priority queuing (SP), weighted round robin (WRR) queuing, and SP+WRR

Connectivity

• Auto-MDI/MDIX Adjusts automatically to straight-through or crossover cables on all 10/100/1000 and 10GBASE-T ports.
• IEEE 802.3X flow control

Provides a configurable flow throttling mechanism propagated through the network to prevent packet loss at a congested node.

• Packet storm protection

Protects against broadcast, multicast, or unicast storms with user-defined thresholds

• Jumbo frame support up to 10-kilobyte frames

Improves efficiency of data transfers by allowing more data into a given packet. This especially useful for transfers of large amounts of data. HPE 1950 Switches support up to 10 kilobyte frame sizes.

• IEEE 802.3at Power over Ethernet (PoE+)

Delivers power to compliant devices over Ethernet cabling, greatly simplifying installation of those devices. The HPE OfficeConnect 1950 Series has two PoE+ enabled models. The PoE+ 802.3at standard supports delivery of up to 30 Watts of power to the attached devices, enough to support the latest models of IP phones, Wireless Access Points, video surveillance cameras, or other PoE/PoE+ enabled devices. HPE 1950 PoE+ models support 370W of total PoE power.

• IEEE 802.3af Power over Ethernet (PoE) ready

Delivers power to compliant devices over Ethernet cabling, greatly simplifying installation of those devices. HPE 1950 PoE+ models are fully backward compliant with the older PoE standard which provides up to 15.4 Watts of PoE power per port to attached devices.

• Available redundant power for PoE+ models

Optional Redundant Power System is available to add power redundancy and to supplement the PoE power of the PoE+ switches. With the optional RPS, the PoE+ power budget can be increased to 740 Watts; additionally, the switch will continue operating and powering downstream PoE devices even if the unit internal power supply should fail. Order the HPE RPS1600 Redundant Power System (JG136A).

• Fully IPv6 capable

-  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

Security

• Access Control Lists (ACLs)

Gives granular control over what traffic goes where in the network. Allows for traffic filtering. ACLs rules can be based on MAC-address or IP-address. ACL rules can be time-based to implement access control during certain hours or days.

• IEEE 802.1X and RADIUS network logins

Controls port-based access for authentication and accountability

·  Automatic VLAN assignment

Assigns users automatically to the appropriate VLAN based on their identity, location and time of day

• Port isolation

T he 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

• 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

• 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

Protects the network by blocking malicious DoS attacks aimed at the switch itself.

• Management password

Provides security so that only authorized access to the Web browser interface is allowed

Performance

• Half-/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 / MLD Snooping

Improves network performance by filtering multicast traffic when there is no multicast receiver on a connection. Without this, multicast traffic is flooded to all ports. IGMP snooping is used in IPv4 networks. The IPv6 equivalent MLD Snooping is also supported.

• 10-Gigabit SFP+ based Fiber Uplinks

Supports high-bandwidth connections over fiber. HPE 1950 Switches each have two SFP+ transceiver slots supporting 10-Gigabit fiber-based connections using optional 10G transceivers. Fiber is particularly suited for connecting at distances beyond the 100 Meter limitation of copper-based Cat 5e cabling. Alternatively use the SFP+ ports for redundant stacking of up to four units using Direct Attached Cables (DAC).

• 10-Gigabit 10GBASE-T RJ45 Uplinks

Supports high-bandwidth connections over Cat 6a cabling. HPE 1950 Switches each have two 10GBASE-T RJ45 ports supporting 10-Gigabit copper-based connections. Cat 6a is economical and practical for distances up to 100 meters. Alternatively use the 10GBASE-T ports for redundant stacking of up to four units.

Layer 2 switching

• VLAN support and tagging Supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs
• 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

Improves network efficiency by filtering unnecessary BPDU packets on a port. When Spanning Tree Protocol (STP) is enabled globally but disabled on specific ports, BPDU packets are not sent out the ports where STP is disabled.

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

• Link aggregation

Groups together up to 8 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. The switch supports up to 128 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 automatically network devices such as IP phones

• Auto voice VLAN

Recognizes IP phones and automatically assigns voice traffic to dedicated VLAN for IP phones

• PoE Models For Converged Voice / Data Networks

Simplifies and lowers the cost of installing a converged infrastructure. Power IP phones, Access Points, Video Surveillance cameras, or other PoE-enabled devices. HPE 1950 Switches support multiple methods of allocating PoE power -- IEEE 802.3af class, LLDP-MED, or user-specified -- for more efficient energy useage.
