Packet Tracer - 备份配置文件

目标

第 1 部分：与 TFTP 服务器建立连接

第 2 部分：从 TFTP 服务器传输配置

第 3 部分：将配置和 IOS 备份到 TFTP 服务器上

拓扑图

背景/场景

本练习旨在展示如何从备份恢复配置，然后执行新的备份。由于设备故障，现在使用一个新路由器。幸运的是，备份配置文件已保存到简单文件传输协议 (TFTP) 服务器上。您需要在尽可能短的时间内从 TFTP 服务器恢复文件，使路由器重新在线。

第 1 部分： 建立 TFTP 服务器连接

注：由于这是个新路由器，将使用与路由器的控制台连接执行初始配置。

点击 PCA，然后点击桌面选项卡，继而点击终端访问 RTA 命令行。

配置和激活 Gigabit Ethernet 0/0 接口。 IP 地址应与 TFTP 服务器的默认网关匹配。

Router>en

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router (config)#interface gigabitEthernet 0/0

Router (config-if)#ip address 172.16.1.1 255.255.255.0

Router (config-if)#no shutdown

测试 TFTP 服务器连接。进行故障排除（如有必要）。

Router #ping 172.16.1.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 172.16.1.2, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 0/0/0 ms

Router #

第 2 部分： 转移 TFTP 服务器配置

a. 在特权 EXEC 模式下，发出以下命令：

Router# copy tftp running-config

Address or name of remote host []? 172.16.1.2

Source filename []? RTA-confg

Destination filename [running-config]? <cr>

路由器会返回以下信息：

Accessing tftp://172.16.1.2/RTA-confg...

Loading RTA-confg from 172.16.1.2: !

[OK - 785 bytes]

785 bytes copied in 0 secs

RTA#

%SYS-5-CONFIG_I: Configured from console by console

RTA#

b. 发出命令显示当前配置。进行了哪些更改？

存储在 TFTP 服务器上的配置

发出相应的 show 命令显示接口状态。是否所有接口都已激活？

否，G0/1在管理上已关闭。默认情况下，所有路由器接口都处于关闭状态。

RTA#show ip interface brief

Interface IP-Address OK? Method Status Protocol

GigabitEthernet0/0 172.16.1.1 YES manual up up

GigabitEthernet0/1 unassigned YES unset administratively down down

Vlan1 unassigned YES unset administratively down down

RTA#

更正与接口问题和测试连接相关的任何问题。

Router (config)#interface gigabitEthernet 0/1

Router (config-if)#ip address 172.31.1.1 255.255.255.0

Router (config-if)#no shutdown

RTA-1#show ip interface brief

Interface IP-Address OK? Method Status Protocol

GigabitEthernet0/0 172.16.1.1 YES manual up up

GigabitEthernet0/1 172.31.1.1 YES manual up up

Vlan1 unassigned YES unset administratively down down

RTA-1#

第 3 部分： 将配置和 IOS 备份到 TFTP 服务器上

将主机名从 RTA 更改为 RTA-1。

RTA(config)#hostname RTA-1

将配置保存至 NVRAM。

RTA-1#copy running-config startup-config

Destination filename [startup-config]?

Building configuration...

[OK]

RTA-1#

c. 使用 copy 命令将配置复制至 TFTP 服务器：

RTA-1#copy running-config tftp:

Address or name of remote host []? 172.16.1.2

Destination filename [RTA-1-confg]?

Writing running-config...!!

[OK - 629 bytes]

629 bytes copied in 0 secs

d. 发出命令显示闪存中的文件。

e. 使用如下命令将闪存中的 IOS 复制至 TFTP 服务器：

RTA-1#copy flash tftp:

Source filename []? c1900-universalk9-mz.SPA.151-4.M4.bin

Address or name of remote host []? 172.16.1.2

Destination filename [c1900-universalk9-mz.SPA.151-4.M4.bin]?

Writing c1900-universalk9-mz.SPA.151-4.M4.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[OK - 33591768 bytes]

33591768 bytes copied in 0.784 secs (4498720 bytes/sec)
