Ticket Please – A ServiceNow Automation PostStandard
Awhile back I did a post on why screen scraping is annoying compared to APIs because you have to spend some effort cleaning up the output before you can use it.
Today we are going to have some fun with Cisco’s PyAts toolset and their Parse_genie Ansible plugin. Ultimately we will parse some output from a Cisco router and use it to create a trouble ticket in ServiceNow!
Let me in! – Fixing Google ChromeStandard
I was sitting on my MacBook thinking about what blog entry I should finish next, when I noticed that my I couldn’t reach my lab stuff when using Google Chrome. It seems like Catalina did something to the certs that makes it think self signed certs are revoked!
I did an interview with NetworkChuckStandard
Tonight I had a chat with NetworkChuck on his youtube channel about what to do after your CCNA and my career. Check it out if your interested: https://www.youtube.com/watch?v=Pni3OhXKmKk
Who needs Quagga? The Cisco Linux RouterStandard
I make several posts talking about how you can use Linux shells on your Cisco device. But what about opposite? In this post we’ll have a look at the Embedded Service Router which is running a full Cisco router application on a Linux host. This is mostly meant for IoT solutions but it is also a great lab solution if you can get your hands on it.
Getting it up – Fixing a down’d mgmt interface on FTDStandard
I had to convert a Cisco ASA 5506 to FTD the other day and baffled because no matter what I did the management interface was admin down / down. This is a problem in FTD since you can’t simply type a no shut and you can’t join it to a FMC without the management interface.
Why You Do That BGP? Best Path Reason Command!Standard
One of the more frustrating things that comes from studying BGP is that it isn’t always obvious why it is selecting one path over another. Fortunately, I came across a cool new BGP feature in modern IOS-XE that explains exactly that!
This can be particularly useful for CCIE study while your working through crazy practice labs.
That’ll Do – Cancelling a Stuck Firepower DeploymentStandard
I love FirePower! It’s great! But every now and then FirePower Management Center gets rebooted during a deployment, and the FMC wants to push the config so much that it will keep on trying for a few thousand hours! While we appreciate the effort, this is a quick way to tell FMC to take a break.
I got something else in the mailStandard
I’m working on some finishing up some actual posts but in the mean time, check out my new socks!
I received a real life reddit post!Standard
Chatting with my router (Webex Team)Standard
Over the holidays I got around to updating some old Cisco Spark stuff over to Webex Teams. Since I haven’t made a post a little bit, I figured I would share some of the fun with you all.
Today we will use Guestshell with EEM to have the router notify us in Webex Teams when the routing table changes!
I’m going to Cisco Live!Standard
I’ll be at Cisco Live in Orlando, come say hi…if you can find me 🙂
I got a stamp!Standard
Chris Lunsford at Cisco tells me that this stamp is very special!
I feel honoured enough to make this post!
So I occasionally stream on TwitchStandard
Man I really need to get around to finishing some posts on here! I got some neat ideas I’m working on finishing soon(ish?)!
In the meantime I have been experimenting with doing some labbing on Twitch at:
I’m currently going over some CCNA/CCNP Security stuff on there so you can check out the recordings if you are interested. They are still a bit rough but I’m getting there. Eventually I will probably either cut up the streams and dump them on YouTube or record them but its all for fun.
Talking with a LISP – A LISP PostStandard
I first started writing this a couple years ago but the post got shelved and my excitement for LISP faded away….Fortunately for us, LISP is making a bit of a comeback because it is a central component of Cisco’s SD-Access / Campus Fabric solution…and I have some time off during the Xmas holidays!
Bossing Cisco Around with AnsibleStandard
I’ve been talking about Infrastructure as Code / Automation / Python a lot with colleagues and peers so I figured I may as well make a quick intro to ansible post since it is just too hot out today.
I’ll preface this by saying, this is only really covered exam wise in the CCIE Written and possibly the cloud track but I figure it might be neat to see. If this is decently well received I might continue on and look at some of the other Evolving Technologies in the written.
Taking a Rest(ful API)Standard
Yesterday we did a quick discussion on what python is all about, I closed things out by showing a simple script that runs a show command and prints the results. Running a script that pushes commands and looks for certain output is called “screen scraping” since python doesn’t know or care what device it connects to and what the output should look like so it just “scraps” the results and lets you deal with it.Yesterday we did a quick discussion on what python is all about, I closed things out by showing a simple script that runs a show command and prints the results.

Print(“A Python Post”)Standard
Python keeps coming up again and again in various networking discussions since people are always debating exactly how much automation stuff you should learn as you get more senior.Python keeps coming up again and again in various networking discussions since people are always debating exactly how much automation stuff you should learn as you get more senior.
Cisco is Coming out of its ShellStandard
I got to play with with the upcoming 16.6 CSR release and it finally has guestshell!
Guestshell is a linux shell that we can access from a Cisco device that lets do some interesting things.
