[Lab environment]
Cisco Packet Tracer 5.3.2
[PURPOSE]
Exercise Cisco IOS backup and upgrade
[Experiment topology]
Lab procedure]
1. connect devices by topology. This time, the 2950 switch is used as the Cisco IOS bearer body because it is easy to configure the router interface. This time, I will take a look at the IP Address Configuration of the switch. The server is still a TFTP server. in the real environment, you only need to install a tftpd software on the PC.
Server IP Address: 1.1.1.250/24
2. Configure the Vlan 1 interface of the switch to configure the management IP address of the switch (it must be in the same network segment as the TFTP server)
Switch # conf t
Switch (config) # int vlan 1
Switch (config-if) # ip add 1.1.1.1 255.255.255.0
Switch (config-if) # no shut
Switch (config-if) # end
Remember that no shutdown is performed after the IP address of the vlan 1 interface is configured.
3. view the existing ios name on the vswitch.
Switch # dir flash:
Directory of flash :/
1-rw-3058048 <no date> c2950-i6q4l2-mz.121-22.EA4.bin
64016384 bytes total (60958336 bytes free)
4. Back up the Cisco ios image to the TFTP Server
Switch # copy flash: tftp:
Source filename []? C2950-i6q4l2-mz.121-22.EA4.bin
Address or name of remote host []? 1.1.1.250
Destination filename [c2950-i6q4l2-mz.121-22.EA4.bin]?
Writing c2950-i6q4l2-mz.121-22.EA4.bin ....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK-3058048 bytes]
3058048 bytes copied in 4.844 secs (631000 bytes/sec)
5. Upgrade the Cisco ios image from the TFTP Server
The 2950 upgrade IOS image file on the TFTP server is c2950-i6q4l2-mz.121-22.EA8.bin
Switch # copy tftp: flash:
Address or name of remote host []? 1.1.1.250
Source filename []? C2950-i6q4l2-mz.121-22.EA8.bin
Destination filename [c2950-i6q4l2-mz.121-22.EA8.bin]?
Accessing tftp: // 1.1.1.250/c2950-i6q4l2-mz.121-22.EA8.bin...

[OK-3117390 bytes]
3117390 bytes copied in 1.875 secs (1662608 bytes/sec)
6. Delete the old IOS image file
Switch # dir flash:
Directory of flash :/
1-rw-3058048 <no date> c2950-i6q4l2-mz.121-22.EA4.bin
2-rw-3117390 <no date> c2950-i6q4l2-mz.121-22.EA8.bin
64016384 bytes total (57840946 bytes free)
Switch # delete c2950-i6q4l2-mz.121-22.EA4.bin
Delete file [c2950-i6q4l2-mz.121-22.EA4.bin]?
Delete flash:/c2950-i6q4l2-mz.121-22.EA4.bin? [Confirm]
Switch # dir flash:
Directory of flash :/
2-rw-3117390 <no date> c2950-i6q4l2-mz.121-22.EA8.bin

7. You can also specify the IOS
Switch (config) # boot system flash: xxx. bin
8. After reload is reloaded, the new IOS will be used.
