Enabling SSH on CSS 11500 series

Hi, I'm trying to convert from Telnet to SSH only. Viewing other posts on NetPro, I'm not really sure if I need to upgrade my License or not. As my show sshd commands are showing output to reflect some sort SSH config. What am I missing here ??

CSS11503# sh ver

Version: sg0810106 (

Flash (Locked):

Flash (Operational):


Licensed Cmd Set(s): Standard Feature Set

CSS11503# show sshd version

SSHield version 1.6.1, SSH version OpenSSH_3.0.2p1

CSS11503# show sshd config

Sshd Configuration Information:


Access Restricted: Yes

Maximum Sessions Allowed: 5

Active Sessions: 0

Log Level: warning-4

Listen Socket Count: 1

Listen Port: 22

Listen Address:

Server Protocol(s): v1 v2

Server Key Bits: 768

RSA Protocol(SSH1): Enabled

Empty Passwords: Rejected

Keep Alive: Enabled

SSH2 Cipher List: aes128-cbc,3des-cbc,blowfish-cbc, etc...

1. In order to migrate to SSH as the only remote access method do I need to upgrade to the "Enhanced Feature Set" and then get the "Secure Management License" from Cisco or can I skip the Enhanced License and go direct to the Secure License?

2. Or do I just do a "no restrict SSH" ?

3. Are there any SSL keys that need to be generated with the "ssl genrsa" cmd or will the licensing upgrade take of this.

Input greatly appreciated!
