Well, when I do a
sh ip ssh
it states that ssh is disabled. So I then copy and pasted my standard line to generate a new rsa key at 4096 and it froze. I then restarted and generated one at 2048 and it generated and enabled SSH. Perhaps this device was not capable of generating a key with a length of 4096 and that was my problem. My standard config I use for our Cisco 4331 routers and 9300 switches generates a 4096 rsa key. Perhaps these smaller devices can only do 2048?
