Cisco 3750 Crypto Key Generate Rsa
May 23, 2017 Once you set the host name and domain-name (ip domain-name whatever), you simply do (in configuration mode) a 'crypto key gen rsa 2048' (or whatever you want the key length to be).I have one 3750 which doesn't have the right feature set for ssh (which I will get around to updating) so check that there is a k8 or k9 in the image name. Apr 25, 2013 Cisco Switching/Routing:: Cat6500 - Crypto Key Generate RSA Command Missing Feb 10, 2013. I recently rebuilt the configuration of our Cat6500 multilayer device for use as a user stack. The device is funtioning as it should be, but I am unable to set SSH using the 'crypto key generate rsa. To generate a key you do need a feature set that supports crypto. This is generally indicated by the presence of 'k9' in the file name of the image file. According to the Feature Navigator on CCO the feature sets in 12.3T would be adventerprisek9, advipservicesk9, advsecurityk9, entservicesk9, and spservicesk9.
Q: I have a Cisco switch in my network, which I can access by hooking up a console cable directly to the device. I like to access the switch remotely using SSH. How can I enable ssh on my Cisco 3750 Catalyst Switch?
A: By default, when you configure a Cisco device, you have to use the console cable and connect directly to the system to access it. Follow the steps mentioned below, which will enable SSH access to your Cisco devices. Once you enable SSH, you can access it remotely using PuTTY or any other SSH client.

1. Setup Management IP
First, make sure you have performed basic network configurations on your switch. For example, assign default gateway, assign management ip-address, etc. If this is already done, skip to the next step.
In the following example, the management ip address is set as 192.168.101.2 in the 101 VLAN. The default gateway points to the firewall, which is 192.168.101.1
2. Set hostname and domain-name
Next, make sure the switch has a hostname and domain-name set properly.
3. Generate the RSA Keys
The switch or router should have RSA keys that it will use during the SSH process. So, generate these using crypto command as shown below.
Also, if you are running on an older Cisco IOS image, it is highly recommended that you upgrade to latest Cisco IOS.
4. Setup the Line VTY configurations
Setup the following line vty configuration parameters, where input transport is set to SSH. Set the login to local, and password to 7.
If you have not set the console line yet, set it to the following values.
5. Create the username password

Note: If you don’t have the enable password setup properly, do it now.

Make sure the password-encryption service is turned-on, which will encrypt the password, and when you do “sh run”, you’ll seee only the encrypted password and not clear-text password.
5. Verify SSH access
From the switch, if you do ‘sh ip ssh’, it will confirm that the SSH is enabled on this cisco device.
After the above configurations, login from a remote machine to verify that you can ssh to this cisco switch.
In this example, 192.168.101.2 is the management ip-address of the switch.
