Generating Rsa Key Cisco Router
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
Jun 28, 2007 Make sure you have specified a host name and domain. Then use the crypto key generate rsa command to generate an RSA key pair and enable the SSH server. When you configure the RSA key pair, you might encounter these error messages: No hostname specified. You must configure a host name for the router using the hostname global configuration command.

First, make sure you have performed basic network configurations on your switch. For example, assign default gateway, assign management ip-address, etc. Google play gift card code generator license key. 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
Generating RSA Keys Problem You want to create a shareable RSA key for authentication or encryption. Solution First, you must create the keys on both devices. We recommend using at - Selection from Cisco IOS Cookbook, 2nd Edition Book. Mar 27, 2017 Use this command to generate RSA key pairs for your Cisco device (such as a router). RSA keys are generated in pairs—one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys.
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.

5. Create the username password
If you don’t have an username created already, do it as shown below.
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.
