思科路由器、交换机的基本管理教程随着Internet的高速发展,网络规模不断膨胀,对于从事网络专业的学生熟练掌握路由器和交换机的配置已显得十分重要。

接下来是小编为大家收集的思科路由器、交换机的基本管理教程方法，希望能帮到大家。

思科路由器、交换机的基本管理教程的方法管理路由器和交换机的方法以及命令主要分为一下几个方面：1、了解命令行的模式。

2、配置接口的IP地址以及相关的路由条目。

3、路由器、交换机密码的管理。

4、远程管理路由器、交换机。

5、系统IOS的备份与恢复。

一、了解命令行的模式1)用户模式默认进入的是用户模式，在该模式下用户受到极大的限制，只能用来查看一些统计信息。

route> #路由器的用户模式switch> #交换机的用户模式2)特权模式在用户模式输入“enable”(可简写为“en”)命令就可以进入特权模式，在特权模式下可以查看并修改路由器或交换机的配置。

route>enable #也可以输入en进入特权模式route#switch>enswitch#在特权模式下常用的命令解释如下：show version ：查看系统IOS版本show running-config ：查看当前的配置信息copy running-config startup-config ：保存当前的配置或者使用 writeerase startup-config ：删除以保存的配置show startup-config ：查看保存好的配置show mac-address-table ：查看交换机的mac地址表show int 接口名称：查看接口的信息show arp ：查看ARP缓存表show ip route ：查看路由表信息show ip int brief ：查看所有接口的IP地址信息。

no ip domain-lookup ：禁用DNS查询line con 0exec-timeout 0 0 ：不超时连接logging synchronous ：不启用时间同步，信息不打断输入命令3)全局模式在特权模式下输入“config terminal”(可简写为conf t)命令就可以进入全局模式，用户在该模式下可以修改路由器或交换机的全局配置。

实验–配置 IPv6 静态路由和默认路由拓扑地址分配表设备接口IPv6 地址/前缀长度默认网关R1 G0/1 2001:DB8:ACAD:A::/64 eui-64 N/AS0/0/1 FC00::1/64 N/A R3 G0/1 2001:DB8:ACAD:B::/64 eui-64 N/AS0/0/0 FC00::2/64 N/A PC-A NIC SLAAC SLAACPC-C NIC SLAAC SLAAC目标第 1 部分：建立网络并配置设备的基本设置•在路由器上启用 IPv6 单播路由并配置 IPv6 编址。

•禁用 IPv4 编址并启用 PC 网络接口的 IPv6 SLAAC。

•使用ipconfig和ping检验 LAN 连接。

•使用show命令检验 IPv6 设置。

第 2 部分：配置 IPv6 静态路由和默认路由•配置直连 IPv6 静态路由。

•配置递归 IPv6 静态路由。

•配置默认 IPv6 静态路由。

背景/场景在本实验中，您将配置整个网络以实现仅使用 IPv6 编址通信，包括配置路由器和 PC。

您将使用无状态地址自动配置 (SLAAC) 为主机配置 IPv6 地址。

还将在路由器上配置 IPv6 静态路由和默认路由，以实现与未直接连接的远程网络的通信。

注意：CCNA 动手实验所用的路由器是采用 Cisco IOS Release 15.2(4)M3（universalk9 映像）的 Cisco 1941 集成多业务路由器 (ISR)。

所用的交换机是采用 Cisco IOS Release 15.0(2)（lanbasek9 映像）的 Cisco Catalyst 2960 系列。

也可使用其他路由器、交换机以及 Cisco IOS 版本。

根据型号以及 Cisco IOS 版本不同，可用命令和产生的输出可能与实验显示的不一样。

请参考本实验末尾的“路由器接口摘要表”以了解正确的接口标识符。

Cisco配置静态路由的方法我们的目的是，要PC0 ping通 PC1，基本思路是设定好所有设备的IP地址，然后再在路由器上配置静态路由。

记得路由与路由之间设置时钟频率(两台路由器之间只设置一个时钟频率)拓扑编址PC0：192.168.1.1 gw：192.168.1.2 PC1：192.168.4.1 gw：192.168.4.2第一步：设置好PC机的IP地址。

第二步：配置三台路由器：Router0：Router 0 >enRouter 0 #conf tRouter 0 (config)#int f0/0Router 0 (config-if)#ip address 192.168.1.2 255.255.255.0Router 0 (config-if)#no shutRouter 0 (config-if)#int s0/0/0Router 0 (config-if)#ip address 192.168.2.1 255.255.255.0Router 0 (config-if)#clock rate 64000设置时钟频率Router 0 (config-if)#no shutRouter 0 (config-if)#exitRouter 0 (config)#Router1：Router>enRouter#conf tRouter(config)#hostname Router1把路由器的名字设置为Router1Router1(config)#int s0/0/0Router1(config-if)#ip address 192.168.2.2 255.255.255.0Router1(config-if)#no shutRouter1(config-if)#int s0/0/1Router1(config-if)#ip address 192.168.3.1 255.255.255.0Router1(config-if)#clock rate 64000Router1(config-if)#no shutRouter1(config-if)#exitRouter1(config)#Router2:Router2>enRouter2#conf tRouter2(config)#int s0/0/1Router2(config-if)#ip address 192.168.3.2 255.255.255.0Router2(config-if)#no shutRouter2(config-if)#int f0/0Router2(config-if)#ip address 192.168.4.2 255.255.255.0Router2(config-if)#no shutRouter2(config-if)#exitRouter2(config)#第三步：配置静态路由：接下来就要用到我们上面的命令了：ip router <目的网段> <目的网段掩码><下一跳>Router0的设置：Router0(config)#ip route 192.168.4.0 255.255.255.0192.168.2.2目的网段目的网段掩码下一跳(下一个路由器的入口)Router1的设置：Router1(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1Router1(config)#ip route 192.168.4.0 255.255.255.0 192.168.3.2注意这里是属于中心路由器，所以要设置两条静态路由，分别指向两边的网段。
