crypto command doesn't work

I'm not sure why, but can someone tell me what I'm doing wrong, I'm trying to setup a cert so I can SSH into the switch, but I keep on getting this invalid input.

So how do I obtain an image with the K9? I bought the switches used and it wasn't from Cisco.

Predrag Jovic

The only legal way is to download it from Cisco's Download Software.

I just thought about it, I haven't tried yet, but if I have a Cisco ID, will that work, I'll try that when I get to my computer. I just remembered I got a Cisco I'd when I got my CCNA.

Or is the IOS have to be purchased?

By the way, besides the ram on the switches, can I install v 15.x on all my switches with crypto? I have all Old switches, mostly 2960's, 3750g, maybe one or two others.

Predrag Jovic

You need to have a contract support, it will not work with your Cisco account (for exam and similar purposes).
You will need to check which version is supported on your WS-C3750G-24PS does not suppot IOS v15

Not sure if, and what would be procedure to purchase IOS separately, but it could be pricey.

Pete Long

This question has already been answered! you need another IOS code base, I had the same problem here. If you have another switch you can use the IOS from that. But as Predrag has pointed out the only LEGAL way, is to get the code from Cisco.

If I were in this situation I'd work out that the code I needed was something like c3750-ipservicesk9-mz.122-55.SE9.bin Then I would know what I needed to DOWNLOAD LEGALLY FROM CISCO OR A CISCO RESELLER. I would not Google the filename and download it from another source.
