Cisco 2960 upgrade IOS

Cisco 2960 IOS upgrade [English]

Motivation:

This manual shows how to upload IOS via FTP or USB disk and upgrade IOS for switch Cisco Catalyst (C2960) series.

Implementation [1]:

In this example we are going to use IOS called c2960c405-universalk9-mz.152-7.E7.bin. IOS image can be downloaded from this pages: https://software.cisco.com/download/home

Example of copy IOS file from FTP server (running under IP address 192.168.1.10) to C2960 series switch:

Cat2960c#copy ftp://yourlogin:yourpassword@192.168.1.10/c2960c405-universalk9-mz.152-7.E7.bin flash:

Progress and successful copy of IOS to C2960c switch flash memory:

Destination filename [c2960c405-universalk9-mz.152-7.E7.bin]?
Accessing ftp://*****:*****@192.168.1.10/c2960c405-universalk9-mz.152-7.E7.bin...
Loading c2960c405-universalk9-mz.152-7.E7.bin !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[OK - 18179072/4096 bytes]

MD5 verification:

Cat2960c#verify /md5 c2960c405-universalk9-mz.152-7.E7.bin

Partial output from MD5 verification:

...............................................................................................................................................................................................................Done!
verify /md5 (flash:c2960c405-universalk9-mz.152-7.E7.bin) = d5fa4b6912bcd5f858577a4cd310bfbd

Set Boot Variable:

Cat2960c(config)#boot system flash:/c2960c405-universalk9-mz.152-7.E7.bin

Check Boot Variable settings:

Cat2960c#show boot | i c2960c405-universalk9-mz.152-7.E7.bin

Partial output from show boot command:

BOOT path-list : flash:/c2960c405-universalk9-mz.152-7.E7.bin

Save running-config to startup-config:

Cat2960c#wr

Reboot switch:

Cat2960c#reload

After reboot check version:

Cat2960c#show version

Partial output from show version command shows that new version IOS 15.2(7)E7 has been loaded and it is working::

Switch Ports Model                     SW Version            SW Image
------ ----- -----                     ----------            ----------
*    1 14    WS-C2960C-12PC-L          15.2(7)E7             C2960c405-UNIVERSALK9-M

Optionally delete old IOS image (in this can it was image c2960c405-universalk9-mz.152-4.E6.bin):

Cat2960c#del flash:/c2960c405-universalk9-mz.152-4.E6.bin

All done.
