Why can't run crypto key generate rsa

I have switch 3548-XL with version 12.0(5.3)WC. When attempting to run crypto key genearte rsa, it doesn't work. Why?

IP200#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

IP200(config)#hostname IP200

IP200(config)#ip domain-name chicagotech.net

IP200(config)#crypto key generate rsa

SSH is not supported on these switches as they are too old i'm afraid.

The 3548 was end of sales in July 2002 (reference).

They do not support ssh (only telnet for vty access) and thus do not have the capability to generate an RSA key.

Re: Why can't run crypto key generate rsa

Can you post sh ver?

In order to run SSH, you need an IOS image that contains "k9" in the name.

example:

c3560e-universalk9-mz.122-55.SE.bin
