Previously I reviewed some high level information of Juniper SRX Firewall. Now I will configure it as my main firewall at home/office/lab. Interface ge-0/0/0 and ge-0/0/7 are by default part of “Untrust” zone already as shown below: I simply moved the ISP cable from my old firewall to the SRX300 port “ge-0/0/0”. It took about… Continue Reading Juniper SRX 300 – Part 2
In this second part I want to review DHCP configuration on the Juniper switch. Part 1 I discussed interface related configurations; most of that stuff can be configured via UI now and CLI and/or CLI command section isn’t needed for that. (NOTE: Personally no matter how good the UI gets, I do like to know… Continue Reading Juniper EX4600 Layer 3 Config – DHCP – Part 2
Deploying a Mist Wireless Network is really easy. The whole process can be automated via UI and/or APIs. I can literally just design everything in Ekahau, drag and drop and be done with it. When it comes to Juniper Switching and it’s integration into the Mist Dashboard, that process is still improving as they continue… Continue Reading Juniper EX4600 Layer 3 Config -Interfaces – Part 1
I was able to get my hands on a brand new Juniper SRX300 Next Gen Firewall, many thanks to @JussiKiviniemi. I have previously worked with Juniper Netscreen product line extensively so looking forward to see what SRX can do and how the interface looks like. Here are few items I am looking to target: Test… Continue Reading Juniper SRX300
Converting a Ruckus AP that is in a vSZ to an Unleashed AP is not something I do often, and it is one of those things that I always forget. I decided to put a quick how-to this time. If you have a Ruckus AP in the vSZ you can SSH into it but you… Continue Reading Ruckus – vSZ AP to Unleash AP
Juniper/Mist devices can be easily claimed via the web UI and/or the Mist AI app on the mobile device. It has been a while since Juniper also added support to claim switches and I just finally had a chance to test it out. For some reason my phone was not able to scan the QR… Continue Reading Python: Bulk rename Juniper switches
API’s and Python are fun. Since I started learning Python and working with Juniper/Mist API’s I am absolutely addicted. There are so many people I am thankful to, who have helped me every time I was stuck and they still do. Recently I dove a little bit into Ruckus APIs. Initially, I almost gave up,… Continue Reading Ruckus vSZ API’s
Previously I discussed utilizing Wireshark I/O Graphs for troubleshooting. In this post I would like to share some thoughts on using the “WLAN Traffic” option for analyzing and troubleshooting purposes. Keep in mind that these tools will not necessarily exactly tell you what the issue is at times. But they are available as part of… Continue Reading Wireshark WLAN Traffic – Troubleshooting
If you work in the IT I am sure you have used, seen and/or heard of Wireshark. It is an awesome free packet capture tool and/or to view captured data. Before I got heavily involved in Wireless, I extensively used it on the wired side of the things sometimes to troubleshoot and sometimes to prove… Continue Reading Wireshark I/O Graphs – Troubleshooting
I am pretty sure everyone knows how to do this but I am writing this anyways because I want to show some appreciation to WLANPi and AirTool 2. I had to capture some 2.4 GHz frames to troubleshoot some issues and I was trying to replicate the issues in my lab. Now I was able… Continue Reading Frame Captures using WLANPi and AirTool2
