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.

Connectivity

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.

Security

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.

Performance

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)

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.

Convergence

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.
