Answered Question

I have a 3750 stack running software version 12.2(25)


Would like to upgrade to 12.4 to have SSH support


I am attempting to use the Software Advisor to see what might be compatible with my devices however my switches do not support the Hardware Configuration commands (show diag) so I am doing the process manually.  I am at the page where it is asking for FRU information.  I have never done this before and don't know how to answer the questions.  Is there a place within the switch I can get this information from (without show diag or show mod)?  Thanks,


Josh

IP Base with crypto is what you need. If you do a "dir flash:" you should see a file like this -


c3750-ipbase-mz.122-25.SEB4.bin


you need -


c3750-ipbasek9-mz.122-25.SEB4.bin

Ganesh,

Thank you for your quick answer.  I have attached a copy of my show version results as I am not sure what you meant by K9.  However, when I attempt to use the "crypto key generate rsa" command my switch does not accept it.  Is there another way I can setup SSH without using this command?  Thanks again for replying.

Hi,


Your current ios wont support ssh as it a ip base series image, For ssh support you need to have cryptogrphy image in your ssh then only your crypto key genrate rsa will work.


cryptography image used to be written with key word K9 in ios.


Hope to Help !!
