S5750E-26X-SI Switch quang 40G L3

Overview

S5750E-26X-SI switch is new generation of intelligent aggregation and access switches designed by DCN for carrier and MAN networks. S5750E-26X-SI provides 24 10GbE (SFP+) and 2 40GbE(QSFP) physical ports and redundant power supplies, designed for 10G access scenario and general network 10G convergence scenario with telecom grade design features of high reliability, and redundancy.

Key Features and highlights

Performance and Scalability

The 10 Gigabit Ethernet connectivity of S5750E-26X-SI is accomplished via a hot-pluggable 10 Gigabit SFP+ transceiver which supports distance up to 300 meters over multimode fiber and 10 to 40km over single-mode fiber (The distance depends on the optical module chosen). S5750E-26X-SI supports built-in redundant AC and DC power supplies for different environment applications.

Easy high-reliability network

Virtual Switch Framework (VSF) could virtualize multiple DCN switches into one logical device, achieves the sharing of information and data tables between different switches. The performance and ports density of the virtualized device is greatly enlarged by times under VSF. VSF also provides simplified management work for the network administrator and more reliability.

G.8032 provides sub-50ms protection and recovery switching for Ethernet traffic in a carrier ring topology. S5750E-26X-SI supports G.8032 v2 and can be deployed in a variety of complex network topologies including single ring, tangent ring, intersecting rings, double rings, and other home networking.

Multi-process MSTP. When a new access ring can be implemented by creating a new process of MSTP, the new ring does not affect the existing traffic. And each process may run different spanning tree protocol.

DCN EMVTE technology (Enhanced Multi-VLAN subnet Traffic Engineering) is a multi-link backup and load balancing solution based on multiple VLAN subnets for the dual-homing network. It can achieve faster switching and convergence of the uplink through the ULPP (Uplink Protection Protocol) and ULSM (Uplink State Monitor) protocol so that network performance is guaranteed.

Enhanced Security

IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server.

Ingress/Egress Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers information. And for some services that are based on time, the product can support time-based ACL to match the requirement.

S5750E-26X-SI support DHCP snooping, which prevents DHCP attacks and illegal DHCP SERVER by setting trust ports and untrusted ports. With DHCP Snooping binding and option82 enabled, it can combine modules like dot1x and ARP, or implement user-access-control independently.

S5750E-26X-SI supports many more L2 security features such as ARP guard, Anti-ARP scanning, and other ARP and MAC Security technology to protect network security and reliability.

Abundant Multicast Features

S5750E-26X-SI also supports MVR (Multicast VLAN Register), selectively allows traffic to cross between different VLANs for bandwidth and security reasons. With the MVR Trunk function, which could associate multicast VLAN to trunk port, S5750E-26X-SI combines the VLAN data into the same link, saving lots of resources for users.

S5750E-26X-SI could prevent multicast traffic from flooding via IGMP Snooping, while multicast traffic is only forwarded to ports associated with multicast devices.
