Features and Benefits

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).

·         SNMPv1, v2c

Enables devices to be discovered and monitored from an SNMP management station.

·         Port mirroring

Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring.

·         Dual flash images

Provides independent primary and secondary operating system files for backup while upgrading.

·         Network Time Protocol (NTP)

Synchronizes timekeeping among distributed time servers and clients; keeps timekeeping consistent among all clock- dependent devices within the network.

·         Manual network time configuration

Manually set the date and time on the switch in the absence of an NTP server.

·         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 falls back to a default, fixed IP address.

 

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.

·         Broadcast control

Allows limiting of broadcast traffic rate to reduce unwanted network broadcast traffic.

·         IEEE 802.1p/Q

Overview

Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q.

 

Connectivity

 

• Auto-MDI/MDIX

Automatically adjusts for straight-through or crossover cables on all ports.

·         IEEE 802.3X flow control

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

·         Loop protection

If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms.

·         SFP ports for fiber connectivity

Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support; SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports. SFP ports available on 24- and 48 port models.

·         IEEE 802.3af PoE-powered device option

Obtains power provided by a standard PoE device connected to Port 1; deploy the switch wherever an Ethernet cable can reach as a power outlet is not needed (8-port GbE non-PoE+ model only).

·         IEEE 802.3at Power over Ethernet (PoE+)

Provides up to 30W 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 802.3af-compliant end device; lowers the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments.

·         PoE+ port availability

Ports 1-4 provide PoE+ on the HPE 1820-8G-PoE+ (65W) switch. Ports 1 – 12 provide PoE+ on the HPE 1820-24G-PoE+ (180W) switch. Ports 1-24 provide PoE+ on the HPE 1820-48G-PoE+ (370W) switch.

·         Auto PoE power configuration

The switch automatically assigns the required power to a port for a PD device based on LLDP (Link Layer Discovery Protocol). Optionally, the switch permits manual, per port, PoE power configuration.

·         PoE shut down mode

A PoE scheduler provides the ability to define the hours of PoE power being supplied on a group of switch ports based on a 24 hour day. The scheduler enables the flexibility to select individual days of a week as well as reoccurrence on a weekly basis with a start and end date.

·         Energy Efficient Ethernet

Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity.

·         Auto port shut-down

The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection.

·         Energy savings status

The switch provides an estimated cumulative energy savings due to green Ethernet features enabled.

 

Security

 

• Secure Sockets Layer (SSL)

Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.

·         Automatic denial-of-service protection

Monitors nine types of malicious attacks and protects the network by blocking these attacks.

·         Management password

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

Overview

Performance

 

• Half-/full-duplex auto-negotiating capability on every port

Doubles the throughput of every port.

·         IGMP snooping

Improves network performance through multicast filtering, instead of flooding traffic to all ports.

 

Layer 2 switching

 

• VLAN support and tagging

Supports up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups.

·         Jumbo packet support

Improves the performance of large data transfers; supports frame size of up to 9220 bytes.

 

Resiliency and high availability

 

• IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1W Rapid Spanning Tree Protocol (RSTP)

Provides redundant links while preventing network loops.

·         Link aggregation

Brings together groups of 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; the 8 port models support 4 trunks, the 24-port models support 8 trunks and the 48-port models support 16 trunks. The 8- and 24-port switches can support up to 4 ports per trunk, the 48-port switches can support up to 8 ports per trunk

 

Ease of use

 

• Locator LED

Allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches.

·         Comprehensive LED display with per-port indicators

Provides an at-a-glance view of status, activity, speed, and full-duplex operation.

 

Flexibility

 

• Flexible installation

Allows mounting on wall, desktop, or under-table with supplied hardware.

·         Rack mountable

All models include rack-mounting hardware for mounting in a standard 19 inch telco rack.

·         Kensington lock slot

Allows switches to be physically secured in open-space deployments (8-,and 24 port models).
