阅读以下说明，回答问题1至问题4，将解答填入答题纸对应的解答栏内。 【说明】 某企业的网络拓扑结构如图4-1所示。图 4-1 由于该企业路由设备数量较少，为提高路由效率，要求为该企业构建基于静态路由的多层安全交换网络。根据要求创建4个VLAN分别属于网管中心、生产部、销售部以及研发中心，各部门的VLAN号及IP地址规划如图4-1所示。该企业网采用三层交换机Switch-core为核心交换机，Switch-core与网管中心交换机Switch1和研发中心交换机Switch4采用三层连接，Switch-core与生产部交换机Switch2及销售部交换机Switch3采用二层互联。 各交换机之间的连接以及接口IP地址如表4-1所示。【问题1】(4分) 随着企业网络的不断发展，研发中心的上网计算机数急剧增加，在高峰时段研发中心和核心交换机之间的网络流量非常大，在不对网络进行大的升级改造的前提下，网管人员采用了以太信道（或端口聚合）技术来增加带宽，同时也起到了(1)和(2)的作用，保证了研发中心网络的稳定性和安全性。 在两台交换机之间是否形成以太信道，可以用协议自动协商。目前有两种协商协议：一种是(3)，是Cisco私有的协议；另一种是(4) ，是基于IEEE 802.3ad标准的协议。 (3)、(4)备选答案： A．端口聚合协议(PAgP) B．多生成树协议(MSTP) C．链路聚合控制协议(LACP) 【问题2】(7分) 核心交换机Switch-core与网管中心交换机Switchl通过静态路由进行连接。根据需求，完成或解释Switch-core与Switchl的部分配置命令。 (1)配置核心交换机Switch-core Switch-coreconfig terminal Switch-core(config)interface gigabitEthemet 0/2 Switch-core(config-if)descnption wgsw-g0/1 // (5) Switch-core(config-if)no switchport // (6) Switch-core(config-if)ip address (7) Switch-core(config-if)no shutdown Switch-core(config)ip route 192.168.10.0 255.255.255.0 192.168.101.2 Switch-core(config)exit (2)配置网管中心交换机Switchl Switchlconfig terminal Switchl(config)no ip domain lookup // (8) Switchl(config)interface gigabitEthemet 0/1 Switchl(config-if)description core-g0/2 Switchl(config-if)no switchport Switchl(config-if)ip address (9) Switchl(config-if)exit Switchl(config)vlan 10 Switchl(config-vlan)name wgl0 Switchl(config-vlan)exit Switchl(config)interface vlan 10 //创建 VLAN10 Switchl(config-if)ip address (10) Switchl(config-if)exit Switchl(config)interface range f0/2-20 Switchl(config-if-range)switchport mode access //设置端口模为 access模式 Switchl(config-if-range)switchport access (11) //设置端口所属的VLAN Switchl(config-if-range)no shutdown Switchl(config-if-range)exit Switchl(config)ip route 192.168.20.0 255.255.255.0 192.168.101.1 Switchl(config)ip route 192.168.30.0 255.255.255.0 192.168.101.1 【问题3]（7分） 为确保研发中心网络的稳定性，在现有条件下尽量保证带宽，要求实现核心交换机Switch-core与砑发中心交换机Switch4的三层端口聚合，然后通过静态路由进行连接。根据需求，完成或解释以下配置命令。 (1)继续配置核心交换机Switch-core Switch-coreconfig terminal Switch-core(config)interface port-channel 10 // (12) Switch-core(config-if)no switchport Switch-core(config-if)ip address (13) Switch-core(config-if)no shutdown Switch-core(config-if)exit Switch-core(config)interface range fastEthemet0/1-4 //选择配置的物理接口 Switch-core(config-if-range)no switchport Switch-core(config-if-range)no ip address //确保该物理接口没有指定的IP地址 Switch-core(config-if-range)switchport //改变该端口为2层接口 Switch-core(config-if-range)channel-group 10 mode on //(14) Switch-core(config-if-range)no shutdown Switch-core(config-if-range)exit Switch-core(config)ip route 192.168.40.0 255.255.255.0 192.168.102.2 (2)配置研发中心交换机Switch4 Switch4config terminal Switch4(config)interface port-channel 10 Switch4(config-if)no switchport Switch4(config-if)ip address (15) Sw:itch4(config-if)no shutdown Switch4(config-if)exit Switch4(config)interface range fastEthemet0/1-4 //选择配置的物理接口 Switch4(config-if-range)no switchport Switch4(config-if-range)no ip address Switch4(config-if-range)no shutdown Switch4(config-if-range)exit Switch4(config) (16) //配置默认路由 Switch4(config)vlan 40 Switch4(config-vlan)name yfl0 Switch4(config-vlan)exit Switch4(config) (17) //开启该交换机的三层路由功能 Switch4(config)interface vlan 40 Switch4(config-if)ip address 192.168.40.1 255.255.255.0 Switch4(config-if)exit Switch4(config)interface range fastEthemet0/5-20 Switch4(config-if-range)switchport mode access Switch4(config-if-range) （18） //退回到特权模式 Switch4 【问题4]（2分） 为了保障局域网用户的网络安全，防范欺骗攻击，以生产部交换机Switch2为例，配置DHCP侦听。根据需求完成或解释Switch2的部分配置命令。 Switch2config terminal Switch2(config)ip dhcp snooping //(19) Switch2(config)ip dhcp snooping vlan 20 Switch2(config)interface gigabitEthemetl/l Switch2(config-if)ip dhcp snooping trust //(20) Switch2(config-if)exit
