交换机部分LS-7506E-X版本一：1、★要求采用CLOS正交多级交换架构，能够配置独立的交换网板与独立的主控板。
主控板、交换网板、业务板物理分离；2、★交换容量≥90Tbps，包转发率≥28000Mpps，业务插槽数量≥6,主控板槽位≥2，支持引擎、单板、电源热插拨，支持主控板卡、电源、接口模块等关键部件冗余配置。
提供官方产品彩页证明；3、★业务板卡与交换网板采用完全正交设计(90度)，跨线卡业务流量通过正交连接器直接上交换网板，背板走线降低为零，极大规避信号衰减；提供官网截图及公开链接证明；4、支持以太网千兆电口，千兆光口，10GE端口、40G端口、100G端口；万兆光口单板密度≥48个，单槽位40G端口密度≥12个，100G接口单板密度≥2个；提供官网链接及选配信息截图证明；5、支持通过核心交换机任意万兆端口(非特定板卡或端口)即可实现将三台以上物理设备虚拟化为一台逻辑上的设备，虚拟化后可实现统一的转发表项、统一的管理界面以及跨物理设备的链路聚合，并且无需独立的硬件模块支持。
6、为适应未来云计算发展趋势，要求设备支持丰富的云计算数据中心特性，如FcoE、TRILL等功能。
7、支持OSPF/IS-IS/BGP GR，支持虚拟路由冗余协议（VRRP）、支持双引擎负载分担；提供软件热补丁技术，实现设备软件完全平滑升级。
8、支持纵向虚拟化，将配套的接入盒式设备虚拟成自身的远程接口板，形成单一的逻辑虚拟设备，在管理层面实现单一节点管理。
9、★支持扩展专用防火墙插卡、IPS插卡、NetStream、负载均衡功能插卡、应用控制插卡，以上扩展模块均为独立硬件，非通过扩展license方式实现，提供官网选配信息截图证明并提供独立的产品彩页。
10、厂商须通过TL9000电信业质量管理体系认证、CMMI4软件能力成熟度认证，提供证书复印件；11、厂商须通过ISO20000信息技术服务管理体系认证、ISO27001信息安全管理体系认证，提供证书复印件；12、★投标产品供应商必需通过知识产权管理体系认证，能够全面保护、并系统管理知识产权，支撑企业的技术创新能力，提供知识产权管理体系认证证书；13、配置要求：单台设备需配置双主控引擎、交换网板≥1块、交流电源≥3块；配置同时可用千兆电口≥24个、万兆SFP+光口≥4个、千兆光口≥20个；版本二：1、交换容量≥96Tbps，包转发率≥28800Mpps，提供官方产品彩页证明；2、★要求采用CLOS正交多级交换架构，能够配置独立的交换网板与独立的主控板。
