Cisco Catalyst 3550系列智能化以太网交换机包括下列配置:
  • Catalyst 3550-24交换机 -- 24个10/100端口和2个基于千兆位接口转换器(GBIC)的千兆位以太网端口;1机架单元(RU)
  • Catalyst 3550-24 PWR交换机 -- 24个带有集成化馈线电源的10/100端口和2个基于GBIC的千兆位以太网端口;1 RU
  • Catalyst 3550-24-DC交换机 -- 24个10/100端口和2个基于GBIC的千兆位以太网端口;1 RU;直流供电
  • Catalyst 3550-24-FX交换机 -- 24个100FX端口和2个基于GBIC的千兆位以太网端口;1 RU
  • Catalyst 3550-48交换机 -- 48个10/100端口和2个基于GBIC的千兆位以太网端口;1 RU
  • Catalyst 3550-12G交换机 -- 10个基于GBIC的千兆位以太网端口和2个10/100/1000BaseT端口;1.5RU
  • Catalyst 3550-12T交换机 -- 10个10/100/1000 Base-T端口和2个基于GBIC的千兆位以太网端口;1.5 RU
内置的千兆位以太网端口可以支持多种GBIC收发器,包括Cisco GigaStack GBIC、
1000Base-T、1000BaseSE-SX、1000Base-LX/LH、1000Base-ZX 和CWDM GBIC。针对快速以太网配置的、基于双GBIC的千兆位以太网实施方案可以为客户提供高度的部署灵活性,使客户可以在目前先部署一种堆栈和上行链路配置,然后在将来移植这种配置。高水平的堆栈永续性还可以通过下列技术实现:两个冗余千兆以太网上行链路,一条冗余的GagaStack GBIC 回送线路,用于高速上行链路和堆栈互联故障恢复的UplinkFast 和 CrossStack UplinkFast技术,用于上行链路负载均衡的单VLAN生成树+(PVST+)。这样的千兆位以太网灵活性使得Catalyst 3550系列成为了针对以太网优化的Cisco Catalyst 6500系列核心LAN交换机的最理想的LAN边缘补充产品。
Catalyst 3550-24、3550-24 PWR、3550-24-DC、3550-24-FX和3550-48中内置了标准多层软件镜像(SMI)或者增强多层软件镜像(EMI)。SMI功能集包括高级QoS、速率限制、访问控制列表(ACL),以及基本的静态和路由信息协议(RIP)路由功能。EMI提供了一组更加丰富的企业级功能,包括基于硬件的高级IP单播和多播路由,以及Web缓存通信协议(WCCP)。在完成初期部署之后,EMI升级工具包为用户提供了升级到EMI的灵活性。Catalyst 3550-12T和3550-12G只提供了EMI。
