H3C S1850-28P Series Gigabit Web Managed Switches

H3C S1850-28P Series Gigabit Web Managed Switches

H3C’s 1850 Series includes advanced Gigabit Ethernet switches in fixed configurations with intelligent management capabilities designed for small businesses that require easy-to-administer solutions. Due to the use of the most modern element base, devices in this series are among the most energy efficient on the market.

The S1850 series is represented by four models: three models without support for powering devices twisted pair and one model with PoE+ support. All models are equipped with additional Gigabit Ethernet SFP ports for fiber optic connections.

This series is part of the H3C line of solutions for small business networks. These switches are competitively priced and include features that meet the latest small business networking needs. All models support rack mounting or desktop installation. Configurable features include basic Layer 2 capabilities such as virtual local area networks (VLANs) and link aggregation, as well as a number of advanced capabilities such as Layer 3 static routing, IPv6, access control lists (ACLs), and STP protocols.

Ability to manage the switch even for users without deep technical knowledge thanks to an intuitive graphical interface, supporting connections via HTTP and HTTP Secure (HTTPS).

Single IP address for management

Ability to manage a group of up to 32 H3C S1850 switches through one web interface, making it easy to manage multiple devices.

SNMPv1, v2c and v3

Simplies switch management because the device can be discovered and monitored from an SNMP management station.

Management interface security

Restricting access to critical configuration commands; various levels of privileges with password protection; access control lists (ACLs) for Telnet and SNMP connections; logging all access attempts using a local or remote syslog server.

Full logging of all sessions

The ability to obtain detailed information to identify and resolve problems.

Port mirroring

Possibility of parallel transmission of all traffic passing through the port to a network analyzer for monitoring.

Two software images in flash memory


Independent copies (main and backup) of operating system files for backup during updates.

Protocol network time (NTP)

Clock synchronization between distributed servers and clients; Ensuring a consistent time across all time-sensitive devices on a network to support a variety of time-sensitive applications.

Limited Command Line Interface (CLI) capabilities )

Ability to quickly deploy devices and diagnose device faults on the network.

Default DHCP client mode

Allows you to connect the switch to the network immediately, without configuration, “plug and play” principle; If there is no DHCP server on the network, the switch will switch to a unique static address mode, determined depending on the MAC address of the switch.

Supports FTP, TFTP and SFTP


Various mechanisms for updating configurations; FTP supports two-way file exchange over a TCP/IP network; Trivial FTP (TFTP) is a simpler file transfer mechanism based on the UDP protocol; Secure File Transfer Protocol (SFTP) runs on top of the SSH tunnel for added security.

Remote Monitoring (RMON)

Use the standard SNMP protocol to monitor basic network functions; support for event, alarm, history and statistics groups, as well as private alarm extension groups.

Quality of Service (QoS) management

Traffic prioritization

Ensuring priority in forwarding time-sensitive packets (such as VoIP and video) over other traffic based on classification by DSCP or IEEE 802.1p; packets are distributed across eight hardware queues for more efficient use of bandwidth.

IEEE 802.1p/Q

Forwarding data to devices taking into account the priority and type of traffic; IEEE 802.1Q support.

Class of Service (CoS)

Tag assignment IEEE 802.1p priority based on IP address, Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ token.

Broadcast control

Ability to limit the rate of broadcast traffic to reduce unwanted multicast traffic on the network.

Service quality management based on extended classification

Traffic classification according to multiple criteria depending on level 2, 3 and 4 information; applying quality of service (QoS) policies, such as setting a priority level and limiting the rate of certain traffic at the individual port level.

Limiting the data transfer rate

Assignment of the maximum speed limit for incoming traffic at the port level and the minimum speed at the queue and port levels.

Powerful quality of service management capabilities

Supports the following congestion response mechanisms: Strict Priority Queue (SP), Weighted Round Robin (WRR), and SP+WRR.



IPv6 Host

Ability to install and manage switches at the edge of an IPv6 network over this network.

IPv6 routing

Support for IPv6 static routes.< /p>

Monitor MLD traffic

Forward IPv6 multicast traffic to the appropriate interface to avoid flooding traffic propagation.

Access control lists (ACLs)/QoS for IPv6

Supports ACLs and QoS mechanisms for IPv6 network traffic.

IEEE 802.3X flow control

Support for mechanisms to slow down the flow when propagating over the network to avoid packet loss on an overloaded node.

Powering devices over twisted pair cable according to IEEE 802.3at (PoE+)

Up to 30 W per port, which provides support for the latest PoE+ devices, such as IP phones, wireless access points, CCTV cameras and any other IEEE 802.3af standard end devices; eliminates the cost of additional power and outlet wiring that would otherwise be required to install IP phones and wireless devices.

Cable Diagnostics

Remotely detect cable problems using a browser-based tool.

Flow control< /p>

IEEE 802.3x backpressure to reduce congestion during high traffic volumes.

Automatic MDI/MDI-X mode selection

Automatic adjustment to cable layout (standard/crossover) on all 10/100/1000 Mbps ports .


Advanced access control lists (ACLs)

Ensures security by ensuring that only authorized users can access the web-based management interface.


Automatic negotiation of half-duplex/full-duplex mode on each port

Doubles the throughput of each port.

Selectable queue settings

Improves performance by selecting the number of queues and corresponding buffer sizes to best suit the needs of network applications.

IGMP snooping

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

Fiber optic backbone interfaces

Supports long-haul connections using Gigabit Ethernet fiber optic backbone interfaces.

Layer 2 switching

Spanning tree protocol (STP)

Supports IEEE 802.1D – Spanning Tree Protocol (STP), IEEE 802.1w – Fast Spanning Tree Protocol (RSTP) with faster convergence and IEEE 802.1s – Multiple Instance Spanning Tree Protocol (MSTP).
