Other people started using the application. But a funny thing happened soon after I launched. Within a few weeks I had a functioning application that met all my needs.

It’s been around for years, is very well documented, and has great community support. I settled on JHipster, a development platform for building web applications using modern technology: Angular, React or Vue for the client side, and Spring plus Gradle or Maven for the server side. The main goal was to get it working fast.

My project was meant to be a hobby application that would only be used by me and a few friends, so I didn’t spend too much time thinking about a long term roadmap or requirements. But lately I have found myself wanting to branch out, and dabbling more in HTML and UI development.Ī couple of years ago, this natural curiosity led me to start a new side project. The so-called back-end of the software stack. All that’s left is to test your access, reload the switch, and ready the cables.As a Java developer, I have spent most of my professional life working on the parts of software systems that most people don’t see. You’ve made it through the learning process with (hopefully) minimum bumps and bruises, and you’re just about ready to ride off. You can now try to log in from a remote machine to verify that you can ssh to your Cisco switch. Verify SSH access by typing ‘sh ip ssh’ to confirm that the SSH is enabled. Make sure that the password-encryption service is activated. Then, set the privilege exec password with username name privilege 15 secret password. Set the enable password using the enable secret password command. If you have not set the console line yet, you can easily input these values: Choosing a key modulus greater than 512 may take a few minutes. Step 6: Configure access portsĪfter already performing basic network switch configurations, it’s time to generate RSA keys to be used during the SSH process, using the crypto commands shown here:Ĭhoose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. It means there is no other encapsulation supported so there is no need for an encapsulation command. If not, simply type switchport mode trunk. If ISL is supported, you have to issue the switchport trunk encapsulation dot1q on the trunk port configuration. You might already have a template ready for access port configuration, but in case you don’t, here are some commands you should use: Step 5: Configure trunk portsĮnter the command sh int g0/1 capabilities and check the trunking protocol supported. To easily reset the domain back to zero, change the config mode to transparent: Step 4: Configure access ports So, before you add your switch to the network, you’re going to want to set its revision number to zero. This means that the switches will update their VLAN configuration based on the VTP information being sent by the switch with the highest revision number. Your switch will only process data from a neighboring switch coming from the same domain and if the revision number of the neighboring switch is higher than its own. When you set a VTP domain name, the revision number is set to zero-after which each change to the VLAN database increases the revision number by one. The VTP revision numbers determine which updates are to be used in a VTP domain. Hit the show vtp status command to reveal your Virtual Trunking Protocol (VTP) revision numbers. Next, make sure your switch has a set hostname and domain name: Step 3: Check VTP revision number Follow any preset naming assignment your company is using and then assign an IP address on the management VLAN. Unlike with that punny name you gave your home Wi-Fi network, when setting up the hostname for your switch you should probably stick to a more professional and standard naming convention.

You are now connected to the switch and ready to check the output of the following commands: Run Putty and select the 9600 speed serial connection. To do this, you will need to download and install Putty (or a similar, fun-named software tool). Next, use a rollover cable to console into the switch from your computer. If everything checks out, power on the switch and verify that all the indicator lights are in working order. Or, if you are using a spare, check the device hardware and its connected cables for any damages. Check the model number of your shiny new switch.
