Describe the features and operation of VLANs on a switched network
Describe the features of the VLAN trunking protocols including 802.1Q, ISL (emphasis on 802.1Q) and dynmic trunking protocol
Describe the features and operation of 802.1Q Tunneling (802.1QinQ) within a service provider network
Describe the operation and purpose of managed VLAN services
Describe how VTP versions 1 and 2 operate including domains, modes, advertisements, and pruning
Explain the function of the Switching Database Manager [specifically Content Addressable Memory (CAM) and Ternary Content Addressable Memory (TCAM)] within a Catalyst switch
Explain the operation and purpose of the Spanning-Tree Protocol (STP) on a switched network
Identify the specific types of Cisco route switch processors, and provide implementation details
List and describe the operation of the key components required to implement interVLAN routing
Explain the types of redundancy in a multilayer switched network including hardware and software redundancy
Explain how IP multicast operates on a multilayer switched network, including PIM, CGMP and IGMP

附录:
新版本的642-811变化最大,Cisco引入AVVID架构概念,IOS采用Native IOS版本,淡化CATOS;在VLAN中引入802.1Q Trunking(Q in Q) ,Spanning Tree 加入RSTP (802.1w)、 MST、CST,加入的Feature 最多,包括 BPDU Guard、BPDU Filter、Root Guard、Loop Guard等,此外增加UDLD,LACP等协议。

在三层交换机中更加细致的讲述了CEF—Based MLS,对于高可用网络加入RPR,RPR+,IRDP,在HSRP的基础上,增加了VRRP,GLBP,SRM,SLB。对于多播部分加入了IGMPv3,还加入了Cisco IP Telephony技术。QoS是BCMSN的重点,除了传统的WFQ,PQ, CQ还引入了LLQ,CBWFQ,WRRQ以及MQC语言和NBAR Feature。

对于网络分析功能,介绍SPAN,VSPAN,RSPAN和硬件NAM的配置。安全特性除了传统的AAA外,增加了Port Security,802.1X验证,访问列表增加了VACL,RACL,还有全新技术Private Vlan,该技术满足ISP宽带服务的相关需求。

最后介绍当代高速以太网——Metro Ethernet,包括:Sonet,DWDM,CWDM,MPLSoE等新兴技术。
