18.You need to gather the IP address of a remote switch that is located in Hawaii. Whatcan you do to find the address? A. Fly to Hawaii, console into the switch,then relax and have a drink with an umbrella in it. B. Issue the show ip route commandon the router connected to the switch.
C. Issue the show cdp neighbor command onthe router connected to the switch. D. Issue the show ip arp command on the router connected to the switch. E. Issue the show cdp neighbors detailcommand on the router connected to the switch.
标答选择E,但这与《CCNA学习指南第6版640-802》P329页原文中“记住CDP 数据包不经过 Cisco 交换机非常重要,并且只能看到直接连接的设备。这意味着如果你的路由器连接到交换机上,不会看到连接到交换机的其他设备。” 这到底是怎么回事?自相矛盾? 望各位大侠解惑,谢谢
