The series is part of the portfolio of H3C small business networking products. These switches provide a great value, and include features to satisfy even the most advanced small business networks. All models support rack mounting or desktop operation. Customizable features include basic Layer 2 features like VLANs and link aggregation, as well as advanced features such as Layer 3 static routing, IPv6, ACLs, and Spanning Tree Protocols.


* 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).

* Single IP management

Enables management of up to 32 H3C S1850 switches using a single Web interface, simplifies management of multiple devices.

* SNMPv1, v2c, and v3

Facilitates management of the switch, as the device can be discovered and monitored from an SNMP management station.

* Management Security

Restricts access to critical configuration commands; offers multiple privilege levels with password protection; ACLs provide Telnet and SNMP access; local and remote syslog capabilities allow logging of all access.

* Complete session logging

Provides detailed information for problem identification and resolution.

* 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 so that the devices can provide diverse applications based on the consistent time.

* Limited CLI

Enables users to quickly deploy and troubleshoot devices in the network.

* 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 will fall back to a unique static address determined by the switch's MAC address.

* FTP, TFTP, and SFTP support

Offers different mechanisms for configuration updates; FTP allows bidirectional transfers over a TCP/IP network; trivial FTP (TFTP) is a simpler method using User Datagram Protocol (UDP); Secure File Transfer Protocol (SFTP) runs over an SSH tunnel to provide additional security.

* Remote monitoring (RMON)

Uses standard SNMP to monitor essential network functions; supports events, alarm, history, and statistics group plus a private alarm extension group.

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.

* IEEE 802.1p/Q

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

* 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.

* Broadcast control

Allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic.

* Advanced Classifier based QoS

Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a per-port basis.

* Rate limiting

Sets per-port ingress enforced maximums and per-port, per-queue minimums.

* Powerful QoS feature

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


* IPv6

- 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.

* IEEE 802.3X flow control

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

* 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.

* Cable diagnostics

Detects cable issues remotely using a browser-based tool.

* Flow control

Provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations.

* Auto MDI/MDI-X

Adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports.


* Advanced access control lists (ACLs)

Enables network traffic filtering and enhances network control using MAC- and IP-based ACLs; time-based ACLs allow for greater flexibility with managing network access.

* IEEE 802.1X and RADIUS network logins

Controls port-based access for authentication and accountability.

* Secure Socket Layer (SSL)

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

* Port Isolation

The 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.

* Port Security

Combines and extends IEEE 802.1X and MAC authentication to provide MAC-based network access control.

* 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.

* Automatic VLAN assignment

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

* 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

Monitors for malicious attacks and protects the network by blocking the attacks.

* Management password

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


* Half- and full-duplex auto-negotiating capability on every port

Doubles the throughput on 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 snooping

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

* Fiber uplink

Provides greater distance connectivity using Gigabit Ethernet fiber uplinks.

Layer 2 switching

* 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

Drops BPDU packets when STP is enabled globally but disabled on a specific port.

* Jumbo frame support

Supports up to 10 kilobyte frame size to improve the performance of large data transfers.

* VLAN support and tagging

Supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs.

Layer 3 switching

* 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 multiple ports up to a maximum of eight ports per trunk either automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the network backbone; help prevent traffic bottlenecks. The 8 port models support 4 trunks, 16 and 24 port models support 8 trunks, 48 port models support 16 trunks.


* LLDP-MED (Media Endpoint Discovery)

Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones.

* PoE allocations

Supports multiple methods (automatic, IEEE 802.3af class, LLDP-MED, or user-specified) to allocate PoE power for more efficient energy savings.

* Auto voice VLAN

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