Brocade Switch: How To Configure SSH And Disable Telnet On The FCX and ICX Series Switches

I personally think its a good idea, from a security standpoint, to enable SSH and to disable telnet.  Why?  Because passwords sent over a telnet session are in clear text, whereas with SSH, they are encrypted.  Dont believe that telnet is not secure?   Take a look at this post I did some time back. 

I have to tell you that I thought about this after I read one of Javier's posts at his blog.  It was a reminder of what I already knew, but he shows you how to enable SSH as well, and I thought about the security aspects of this and about how many attacks actually come from the inside of the network.  It was this post:  Enabling SSH on the ICX6610.  Check out Javier's blog.

So how do you enable SSH and disable telnet on a Brocade switch?  Ill show you the config:
Switch#config t
Switch(config)#crypto key generate rsa
Switch(config)#username shanekillen pri 0 password passphrase
Switch(config)#aaa authentication login default local

Switch(config)#no telnet server


  1. I seem to keep finding myself on your site! This is exactly what I was looking for, gets right to the point. Thanks for your testimony through this blog and wanting to help out others. Now if they would all just repent and believe!


    1. Hey Jerry. I hope you are doing well. I appreciate the kind words. Thats really kindof the whole point to this blog for me. To help others on a technical basis (and myself, since I also refer to it) and to tell others the good news of the gospel. Jesus did a wonderful thing for us. Everyone needs to at least know about it, right? :)

    2. And you know this about Jesus how? The most regarded authority on this is the KJ bible. With it's numerous contradictions and obvious false holds including the narrative on Jesus crucifixion and stating that the earth is flat, surely you can't consider that reliable

    3. Man, you obviously don't know much about the Bible. You make that very obvious in what you say. You also think that the kj version is the most regarded, which again is false. And you think the Bible says the world is flat, which again, it says it's round. I really can't take you seriously at all. But thanks for showing your true ignorance, even though you do it anonymously.

  2. This is also what I am looking for. Great answer and get to the point. Thank you for sharing.

  3. Well well ... looking up some stuff for our Brocade and I run across this. Shane Killen. Thanks for the quick tip and keep spreading the word. :)
