F5 monitors

I successfully completed the 4 day F5 LTM configuring v11 course. I am very happy with the amount of information covered and the teacher was very knowledgeable. Now that I’m back at work, I have already applied some of the knowledge I’ve obtained.

I was assisting another individual with setting up an http monitor that was using a send/receive string. We were having issues in getting the monitor to work. We struggled in where the CR/LF characters needed to be and how many to use. Each version of LTM seems to operate a little different and we found that out from the SOL10655 publication on the askf5 knowledge base. After going through some additional docs, we still couldn’t get the monitor to work. After trial and error, the monitor finally started working after we changed the HTTP version from 1.1 to 1.0.


Send String: GET /your/page/page.html HTTP/1.0\r\n Host: anynamewilldo\r\n\r\n

F5 Training

Today I’m starting a 4 day F5 online training course. The course will be going over how to setup and configure their BIG-IP LTM (local traffic manager) product. The LTM main feature is load balancing application traffic. For those of you who aren’t familiar with F5, they offer an extensive line of application delivery service products. The LTM is just one of their many product offerings. F5 offers some great introductory study material on their F5 support site. I would recommend starting there if you’re interested on learning about LTM.


Hi, my name is Javier Solis and I’m currently a network and infrastructure supervisor serving the Purdue University Northwest campus. I have been engrossed in the world of IT since the start of my freshmen year of high school back in 1998. I have also been blessed to carry 2 core jobs since the start of my career as an IT student worker at the former Purdue University Calumet in Hammond.

My first full-time job was at a small WISP in Northwest Indiana. We were small in the eyes of the local telco providers such as ATT and Comcast, but pretty large for a shop run by just a few employees. We heavily ran the Motorola canopy line and primarily used mikrotik routers. I then had the opportunity to move up to Wisconsin under contract by the same WISP to manage and deploy a 2.5 square mile municipal wifi cloud on my own. It proved to be quite a task, but I learned a great deal.

Five and a half years after working at that WISP, I took an offer to work as a full time network administrator back at Purdue University Calumet. Five and a half years working at the Hammond campus, there was a unified with the Westville regional campus. I’ve since been serving in a supervisory role at Purdue Northwest for over a year. It’s funny how we find ourselves back where we started, but I’m learning more than ever. I enjoy sharing my experiences with others and hopefully, you’ll enjoy this blog. I also look forward to hearing from anyone out there. You can also find me on twitter at @javi_isolis.
