Cisco ASR920 Problem

This was an interesting evening. I went onsite to a customer and put in one of those TZ600 SonicWall firewalls I just configured. Once I got it in place, I noticed the normal ARP issue that you have on the next hop router. So I rebooted the ISP router.  As it turns out, there is a firmware issue on these Cisco ASR920 routers that when you reboot the system, if you have fiber modules in the ASR, it can cause an issue forwarding traffic, even though the interfaces are up. The fix? Literally, pull out the Gbic modules and re-seat them.  All OK after that.

Two SonicWall TZ600s

This week, I have two SonicWall TZ600 firewalls to get setup for a company. They will have site to site VPN and will provide these small offices with some security.  It's certainly not an enterprise solution, but OK for a small office like these.

It's Never Ending...

Just keep in mind, when it comes to security of company data, everyone is a target. You have to protect yourself with appropriate cyber security. Sonic was the latest we have heard of. Who is next?

Types Of Learners

Have you ever considered how you learn things the best? Recently, I have. I've tried to give some real consideration to why I get distracted so easily when studying for a particular certification. You see, I'm an auditory learner. For whatever reason, it's just how God made me.  So when I hear noises around me, I've found I get distracted from actually studying. It turns out that I need silence to best accomplish my studying. And even more odd, when I study, I need to actually speak it out and hear myself say it. I've done this in the past, and can recognize that this IS actually correct for me.
I would encourage you to figure out your learning style. Just in life in general, it's probably a good idea to know about yourself. God made everyone of us carefully and specifically. We should probably look at ourselves and how we were made in order to become what we are supposed to be in this life.
Go try this test out and see what your learning style is: Learning style

When I look up what kind of learning tips are best for me, this is the sort of thing that comes up, which I can verify is true:

Sunday Thought: One Mouth, Two Ears

Have you ever heard that phrase "God gave us one mouth and two ears"?
There is that Bible verse about being quick to listen and slow to speak (James 1:19). You have also heard that phrase "seek to understand, then be understood"?
Let's commit to that. To understand first, then to be understood.

Cisco PBR And The SDM Prefer Command

Cisco has some good features in their switching gear. Like most vendors, they do policy based routing also.
I found myself in a small predicament. You see, my customer has this 7450 Brocade switch, which is way better than any campus Cisco access switch on the market. The only thing was, they didn't have the premium license needed for PBR. But, it just so happened that there was an old 3560 switch laying around, and PBR was an active feature on it. The only thing I had to do was to do the "sdm prefer routing" command and a reload, and it was ready for configuration. PBR is a great feature. As one of my old bosses put it, "them's the big boys".
Before config, I decided to draw it out.

White Rhino Security

You guys know that when you go somewhere in your car, and you get out to go inside your destination, do you lock your car doors? If so, why?
Most of us answer yes, we do lock our doors when we leave it. Why? Because we don't want anyone getting what we leave inside the car.
So, do you consider your company data and employee data of the same importance? Do you lock the internet doors to your company? The cybersecurity door?
Contact me on the right side of this page, and let's discuss your security concerns. Or at a minimum, let me get you educated on what you should be thinking about.

Out Of Town Weekend

Needtobreathe played a concert in Memphis this weekend, so we decided to take a small roadtrip. It's only a couple of hours from Birmingham and we decided to do some of the things we used to do years ago, along with the concert.
Always work hard during the week, and take some fun time on the weekends. And always thank God for the blessings you have. He is a good God, just believe and trust in that, no matter where you are in life.
Here we are at the Peabody Hotel.

Cross Training

I have the opinion that investing in people is important. One way to do that is by cross training people in certain IT fields.
Currently, I'm in the process of training a few routing and switching guys to be firewall guys also. And vice versa. It's interesting to hear the conversations that are taking place between the two groups now. I have started easing back to the back of the room and i just listen, and I'm thrilled to hear the two groups intermingle with each other, now without me prompting the conversations and guiding it through. I'm excited and thrilled, to say the least. I really enjoy watching people grow in their careers.
