Bài lab làm việc với tftp server

Mô tả

Backup các file cấu hình của switch vào TFTP server
Nạp lại file backup từ TFTP server.

Thực hiện
1. Đặt IP address cho host có TFTP server



2. Đặt IP address cho management VLAN

Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname ALSwitch
ALSwitch(config)#int vlan 1
ALSwitch(config-if)#ip address 10.1.1.251 255.255.255.0
ALSwitch(config-if)#no shut

3. Cấu hình cho port gắn với TFTP server ở access mode (giả sử là port f0/9)

ALSwitch(config-if)#int f0/9
ALSwitch(config-if)#switchport mode access
ALSwitch(config-if)#switchport access vlan 1
ALSwitch(config-if)#no shut
ALSwitch(config-if)#
01:38:36: %LINK-3-UPDOWN: Interface FastEthernet0/9, changed state to up
01:38:36: %LINK-3-UPDOWN: Interface FastEthernet0/9, changed state to up

4. Kiểm tra kết nối giữa switch với tftp server



ALSwitch#ping 10.1.1.10

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/5 ms

6. Copy cấu hình hiện tại vào tftp server
ALSwitch#copy running-config tftp
Address or name of remote host []? 10.1.1.10
Destination filename [running-config]? running-config.txt
!!
685 bytes copied in 1.106 secs (685 bytes/sec)
ALSwitch#

7. Copy startup-config vào tftp server
ALSwitch#copy startup-config tftp
Address or name of remote host []? 10.1.1.10
Destination filename [startup-config]? startup-config.txt
!!
685 bytes copied in 0.84 secs
ALSwitch#

8. Copy file config.text từ flash vào tftp server

ALSwitch#copy flash:config.text tftp
Address or name of remote host []? 10.1.1.10
Ấn EnterDestination filename [config.text]?
!!
685 bytes copied in 0.89 secs

Chú ý file startup-config.txt và config.text có nội dung giống nhau.

9. Copy biến môi trường vào tftp server để xem tham số
ALSwitch#copy env_vars tftp
Address or name of remote host []? 10.1.1.10
Destination filename [env_vars]?
!!
17 bytes copied in 0.79 secs
ALSwitch#

10. Copy bootfile vào tftp server
ALSwitch#copy bootfile tftp
Address or name of remote host []? 10.1.1.10
Destination filename [bootfile]? switch2900XL.bin

cisco WS-C2912-XL (PowerPC403GA) processor (revision 0x11) with 8192K/1024K
...

File Switch2900XL.bin có kích thước giống file c2900XL-c3h2s-mz-120.5.2-XU.bin có sẵn trong flash

11. Upload lại file từ tftp lên switch

ALSwitch#copy tftp:c2900XL-c3h2s-mz-120.5.2-XU.bin flash
Address or name of remote host []? 10.1.1.10
ẤnDestination filename [c2900XL-c3h2s-mz-120.5.2-XU.bin]? Enter
