how to upgrade cisco switch ios via tftp

 =========STEPS TO UPGRADE CISCO DEVICE IOS=======

Here's a mock-up of the Cisco CLI output for your reference, following the steps you provided.

Step 1: Login to the Device (Console Access)

Router> enable
Router# 

(You are now in privileged EXEC mode)

Step 2: Assign an IP Address to VLAN 1

Router# configure terminal
Router(config)# interface vlan 1
Router(config-if)# ip address 192.168.1.1 255.255.255.0
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# exit
Router#

(You have assigned an IP address to VLAN 1 and brought it up)

Step 3: Download the Latest IOS from Cisco Website

(This is done externally via a web browser from the Cisco website.)

Step 4: Connect Your System via Console and Ethernet Cable

(Ensure your PC is physically connected to the Cisco device.)

Step 5: Assign an IP Address to Your Ethernet Adapter on the PC

(On your computer, configure the Ethernet adapter manually with an IP in the same network, e.g.:)

• IP Address: 192.168.1.6
• Subnet Mask: 255.255.255.0
• Default Gateway: 192.168.1.1

Step 6: Download and Open TFTP64/32 Application

(Download and install TFTP64 or TFTP32.)

Step 7: Configure TFTP Server

• Open the application.
• Select the network adapter (e.g., 192.168.1.6) under the settings.

Step 8: Place the Downloaded IOS File in the TFTP Server Directory

(Move the downloaded .bin file to the directory that TFTP64/32 uses as its root directory.)

Step 9: Copy the IOS Image to the Cisco Device

Router# copy tftp://192.168.1.6/c2960cx-universalk9-mz.152-7.E5.bin flash:
Address or name of remote host []? 192.168.1.6
Source filename []? c2960cx-universalk9-mz.152-7.E5.bin
Destination filename [c2960cx-universalk9-mz.152-7.E5.bin]? (Press Enter)
Accessing tftp://192.168.1.6/c2960cx-universalk9-mz.152-7.E5.bin...
Loading c2960cx-universalk9-mz.152-7.E5.bin from 192.168.1.6 (via VLAN 1): !!!!!!!!
[OK - 25000000 bytes]

(The transfer will take some time, depending on file size and network speed.)

Step 10: Configure Boot System

Router# configure terminal
Router(config)# boot system flash:c2960cx-universalk9-mz.152-7.E5.bin
Router(config)# exit
Router#

Step 11: Reload the Device

Router# reload
Proceed with reload? [confirm] (Press Enter)

(The device will now reboot and load the new IOS.)

Step 12: Verify the New IOS After Reboot

Router# show version
Cisco IOS Software, C2960CX Software (C2960CX-UNIVERSALK9-M), Version 15.2(7)E5, RELEASE SOFTWARE (fc1)
...

(Ensure the new IOS version is displayed in the output.)

Final Check

Router# show flash:
Directory of flash:/

  1  -rw-    25000000  Jan 26 2025 08:30:00  c2960cx-universalk9-mz.152-7.E5.bin

(Verify the IOS file is in flash memory.)

This is a full mock-up of how the CLI should look at each step. If you're performing these steps, you can take real screenshots from your terminal window.
