The Centec E350 Series Routing Switches are high performance Ethernet switches to meet next generation Metro, Data Center and Enterprise network requirements. The E350 is designed based on Centec’s third generation high-end scalable chipset CTC5160. The E350 comes with complete system software with comprehensive protocols and applications to facilitate rapid service deployment and management for L2/L3/MPLS networks. E350 has open API interfaces and Debian system to achieve SDN.
The E350 Series Switches includes 2 configurations: E350-48T4X and E350-8TS12X.

Table 1: Primary Features in E350 Software
- Multilayer Switching with High Capability at wire-speed
E350-48T4X switch provides 176 Gbps switching capacity and 132 Mpps Layer2&Layer3 packet forwarding rate with wire-speed for all ports. The switch provides 48x1GE Base-T Ethernet ports, and 4x10GE SFP+ ports. E350-8TS12X switch provides 240 Gbps switching capacity. This switch provides 8x1GE Base-T/SFP Combo Ethernet ports and 12x10GE SFP+ ports.
- System Design for Green and Energy Saving
The E350 Series supports the fans with speed control as well as power consumption adjustment which is based on the flow status of the ports. Both can highly save the energy and go for green.
- Customized Profile for Different Deployment Scenarios
The Flexible Table Management (FTMTM) technology employed by Centec E350 Series offers multiple table size configuration profiles as optimized choices for different network scenarios. E350 could support up to 64K MAC address table or 8K IP routing table.
- Intelligent Ethernet OAM: Complete Fault Management and Performance Guarantee
End-to-end OAM based on IEEE 802.1ag and ITU-T Y.1731 enable Ethernet service providers to monitor their services proactively, measure end-to-end performance and guarantee that the customers receive the contracted SLA. Fault management includes CCM, LTM, LBM and performance measurement includes Frame Delay, Frame Delay Variation. E350 series also supports single segment (link) OAM according to 802.3ah for remote management and fault indication, including remote loopback, dying gasp, and MIB parameters retrieval.
- Data Center Features
E350 provides feature support for data center application, such as NvGRE and M-LAG. The E350 also supports the RPC-API, which provides a northbound interface to the switch, can be easily integrated into the data center automated operation or cloud platform.
- Redundancy Design and Robust System
- Hot swap power modules
- AC/DC 1+1 Power module redundancy
- N+1 Fan redundancy
- Real-time environment monitoring for chipset temperature, status of fan and power, etc
- LACP, ECMP, VRRP, VARP, STP/RSTP/MSTP, Smart Link, BFD, ERPS, G.8031/G.8032, MPLS-TP protection for redundancy and load-balancing
- Centec-patented Sysmon for CPU status monitoring and protection upon unpredictable fault
- Outstanding QoS Control with Flexible Classification and Queuing Mechanism
Centec E350 Series provides 8 hardware queues per port to support multi-stage scheduling (WDRR, SP) and Tail Drop/WRED. 3-stage shaping (queue/group/port) can be applied for flow management. Meanwhile, ingress and egress policer provide bandwidth monitoring with a granularity of up to 64Kbps. Both srTCM (Single Rate Three Color Marker) and trTCM (Two Rate Three Color Marker) can be supported.
- Triple-play Service Support with Bandwidth Guaranty for High Quality Application
The Centec E350 Series offers high bandwidth for Triple-Play services such as IPTV, video monitoring. The built-in QoS capabilities and flexible queuing technologies guarantee high quality of services. Rich multicast protocol set (IGMP Snooping, IGMP v1/v2, PIM-SM) supports up to 16K multicast groups, 1K physical replications and 4K logical replications per group. With CentecOS software, IPTV service and multicast time-delay control is fully supported.
- Comprehensive Network Security Policy
The Centec E350 Series supports subscriber-level, switch-level and network-level security control. Basic IPv4/IPv6/MAC ACL is used to filter IPv4/IPv6/Non-IP packet respectively and can be applied to both port and VLAN. Besides that, extended IPv4/IPv6 ACL is also available. In a single ACL rule, both IP and MAC ACE can take effect to filter IP and Non-IP packets simultaneously. Centec ARP Inspection and IP Source Guard features prevent network from malicious ARP attack. CPU Traffic Protection, Storm Control features optimize CPU load. Centralized 802.1x authentication forbids illegal user access to the network.
