S5850 Series Switches Features and Highlights

Versatile Connectivity

  • 24-port models are optional in 1G Ethernet copper and 10G/25G SFP+ connectivity. They can be deployed either as 1G/10G high-speed edge or aggregation switches requiring 25G or 40G uplink speed.

  • 32- and 48-port 10G models are with a variety of 40/100G uplinks, including 10GBASE-T and 10G SFP+ variants to conserve valuable rack space and simplify the migration to 40/100Gbps in the network core.

  • Large 10 Gigabit choice with SFP+ ports for fiber or short, low-latency copper DAC cables. 10GBASE-T ports for legacy Cat6 RJ45 short connections (up to 55m) and Cat6a/Cat7 connections up to 100 m.

Intelligent Ethernet OAM

Ethernet OAM (operation, administration, and maintenance) facilitates operators to monitor and troubleshoot a single Ethernet link. With the IEEE802.1ag and ITU-T Y.1731 end-to-end OAM, the S5850 series enables service providers to monitor the services, survey the end-to-end performance and ensure the service quality matches the agreement. Besides, fault management techniques like CCM, LTM, and LBM are performed to measure latency and jitter. The IEEE 802.3ah EFM (Ethernet in the First Mile), known as the technology that specifies the protocols and Ethernet interfaces for using Ethernet over access links further enables remote management, network monitoring, network fault indication, remote loopback, and MIB parameter retrieval.

Abundant Data Center Features

Though categorized under FS Enterprise Switches, some models of the FS S5850 series switches even deliver line-rate switching at layer 3 to enable faster and simpler network design for data centers to lower the network operational expenses. They can be used in conjunction with other FS data center switches, allowing to scale in high performance and low latency network that provides predictable and consistent application performance. They also support MLAG (Multi-Chassis Link Aggregation) to aggregate links across different devices, thus building an Active-Active system to improve the reliability of the network links from single-board grade to device grade.

High Reliability

The S5850 switches were designed for continuous operations with system-wide monitoring of both hardware and software components. Key high availability features include:

  • 1+1 hot-swappable power supplies and with 3+1 or 2+1 redundant fans to provide dynamic temperature control combined with N+1 redundancy.

  • Real-time environment monitoring technology to detect the chipset temperature, status of fan and power, etc.

  • LACP/ECMP/VRRP/VARP/STP/RSTP/MSTP/Smart Link/BFD/ERPS/G.8031/G.8032/Load-Balancing are supported to effectively protect the network traffic all-around.

  • Patented technology “Sysmon” can monitor the CPU status when system error occurs.

Enhanced QoS Control

FS S5850 series switches offer intelligent traffic management to keep the network running smoothly, delivering superior performance for data, voice, and video traffic. The outstanding QoS features include:

  • Up to 13 hardware queues per-port: 8 unicast queues, 4 multicast queues and 1 monitor queue. Ingress and egress policing are supported for intelligent bandwidth monitoring.

  • Efficiently prevent network congestion with multi-stage scheduling technology such as WDRR (Weighted Deficit Round Robin), SP (Strict Priority), TD (Tail Drop) and WRED (Weighted Random Early Detection).

  • QoS through Differentiated Services Code Point (DSCP) mapping and filtering.

  • QoS through traffic classification.

  • Flexible queue scheduling mechanism to shape queue and port traffic.

  • Support srTCM (Single Rate Three Color Marker) and trTCM (Two Rate Three Color Marker).

Comprehensive Network Security

Multiple security features are also supported by the FS S5850 series to limit access to the network and decrease outside threats, including:

  • Centralized 802.1x authentication feature to the network access, including flexible authentication, 802.1X monitor mode, and RADIUS change of authorization.

  • Support subscriber-class/switch-class/network-class security control.

  • TACACS+ and RADIUS authentication to facilitate centralized control of the switch and restrict unauthorized users from altering the configuration.

  • Access Control Lists (ACLs) for IPv6 and IPv4 security can filter IPv4/IPv6/Non-IP packet respectively. The ACLs can apply to physical ports/VLAN/port group/VLAN group.

  • The members of port group or VLAN group share a set of ACLs and save TCAM resources.

  • ARP inspection and IP source guard features prevent network from malicious ARP attack.

Convenient Management Features

FS S5850 series switches support multiple management interfaces, users can manage the switch through console port, inband/outband network ports, and USB port. Besides, CLI, web management, Telnet and FTP connections are also supported. The web management provides a user interface, which enables easy onboarding of the switch. It also has an intuitive dashboard for configuring, monitoring, and troubleshooting the switch.
