After the introductory lessons of the first two chapters, it is time to begin the practical work with the Cisco Classic Network Firewalls. This chapter focuses on topics such as IP address assignment, Command Line Interface (CLI) usage and how to prepare the devices to be remotely managed using protocols such as Telnet, Secure Shell (SSH) and HTTPS.

Device Access Using the CLI

Even when planning to manage a Cisco Firewall using a Graphical User Interface (GUI), you probably need to take some initial configuration steps via the CLI. The good news, in this case, is that intelligible and intuitive CLIs have always been a recognized asset of Cisco devices. The CLI is typically accessible through a serial console port or by means of terminal access protocols such as Telnet and SSH. In either situation, a terminal emulation program such as TeraTerm, Putty, or HyperTerminal is necessary.

Throughout the book, unless otherwise stated, CLI access is always assumed.

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

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

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.

In this example, 192.168.101.2 is the management ip-address of the switch.
