Being a manager does not make you a leader.
Now that I have your attention, I’ll dive in a little deeper. Think of it in terms of creating a meal. You can look at your pantry and see you are missing certain ingredients to your recipe. You go out to the store and purchase those ingredients. You come back and toss the ingredients in the pantry. Done! The meal has been created. Well actually, no. You have the ingredients you need, but nothing else was done. You still have to spend time putting the ingredients together, cooking the meal, making sure the taste is right, add a ton of salt and pepper, and finally serving it. It’s easy to gather the ingredients listed in a recipe, but it might not be as easy to turn that recipe into the perfect meal. It takes time and effort. The same applies to an engineering team. As a leader, or perhaps a chef, having the ingredients is not enough. In order for an engineer to grow in an environment, work must be done. Yes, some of it falls squarely on the shoulders of the engineer, but some of it comes from leadership. My goal here is to discuss three ingredients that a leader can combine that can make a difference in their team. Continue reading 3 Things Engineers Need from Leaders
As we are busy diving into the world of programming and automation, I’d like to remind everyone of a way to make simple config changes to a Cisco switch or router using a text file. This might not be a breakthrough, but it helps when making changes to switches or routers when those changes can possibly disconnect you from the device. Imagine working on a re-IP of a switch or even a point to point link. You have your notepad ready to go. There is a new IP and default route and all you have to do is copy/paste. You paste in the IP and lose connection. Your default route change never actually pasted because you lost connection right after the IP change. You can no longer connect to the device; panic ensues. What might be a better way to make this change and avoid the “Uh oh!” moment? Continue reading Simple Cisco Text File Changes
So you are interested in networking? I don’t mean attending gatherings, handing out business cards, shaking hands and kissing babies. I mean being a network engineer or administrator? Perhaps you just started the journey at a company and feel slightly lost. If you are, then the following paragraphs are meant for you. This is not only meant to be a motivator to continue learning and applying, but here you will find three things to look for or try to work on that can push you upwards in the work place.
Whether you are part of a small team, large team or riding solo there is much more to network engineering. Sure, there are days where it seems like everyone needs a port configured, but there will be times where you can bring forth your ideas into fruition. There will be times where you look around and figure out ways to improve existing infrastructure. You might be interested in pursuing certain software that can improve a process or provide valid insight. You might want to create or update documentation. You might just want to improve certain aspects of a network, such as routing or security. These are all good things to do, time-permitting and team-willing. If you have good ideas bring them up to your team or your manager. This will not only be a good way to learn, but you can excel career-wise by getting involved and pursuing ways to improve your company. Continue reading Beyond Engineering
Have you ever had a work-related dream that you’ve woken up from and were thankful it was just a dream? Designing and executing the network for a new data center will definitely give you a few night terrors. I recall the night before our data center move, I dreamed that I woke up late on the day of the move. That’s not too bad right? Well for some reason, in my dream the data center was in another state instead of an hour away. Then my car did not start; I had to “borrow” a car and I got lost on the way there. Again, I was thankful it was a dream. The actual move went a bit smoother. However, these types of projects can be real nightmares for teams. The main thing to do is plan. You the follow this with a few healthy doses of additional planning. Continue reading Data Center Move: A Perspective
If you work in networking, you probably take care of the switches and routers in your environment or have some input on what happens with them. Switches are the doorway to the network. Even if you have a wireless device, the access point you connect to is probably connected to a switch. This is where your PCs, TVs, appliances and many other wired devices connect. Routers can manage connections in and out of your environment along with a plethora of other services. Everyone should have a template or standard config they use on any network device. With today’s tools and services like Prime Infrastructure or DNA Center, you can spread that configuration around or deploy it to new sites; however, you still need a config to apply. Different scenarios and environments call for different configuration, but there are always those sets of commands you can use everywhere. The goal of this writing is to share a few commands that are helpful and I typically apply. Most of these are commands you spot all over certification studies and others I’ve seen other engineers use.
Yes, you probably memorized every single command from the CCNA and even the CCNP…but did you apply them all on every single port? Sometimes, unless there is a need you might not have to. I call it, situational configuration. Apply what you need and what will keep the environment secure. The important piece is to be consistent. On switches, VLANs might be different for each interface, but why would some of your switches have “enable password” and others have “enable secret”? Continue reading Network Devices: Easy Config Tips
Imagine driving down a three lane highway at a decent (legal) speed. It’s a beautiful day with the sun high in the sky and a nice cool wind coming in through the window. All is going well. In just a few minutes you should be at your destination. Suddenly, all you see in front of you are red lights. You roll to a stop and realize that ahead of you is construction, converting the three lane highway into a single lane snooze-fest. The construction bottleneck has slowed traffic down to a crawl. Hopefully other drivers will let you in as you inch towards the next lane. If only there was a way to just jump to the front of the lane. Well, in this scenario not so much. However, if this was a network full of layer 2 and layer 3 devices, we would have some ways to organize the traffic in a way that the important traffic (cars) keep moving efficiently through the bottlenecks.
