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):
