Study Session Number 3! Cisco DNA Center and WLC (WLAN Controller) #4


Hi Everyone!

Today I'm going to talk about Cisco DNA (Digital Network Architecture) Center's and WLAN Controller's, this is building on the previous session I had! After discussing these two topics this will cover 1.1 of the Exam Objectives! Woohoo! 

Figure 1 

As this is my study notes I've only discussed the topics that I needed to learn/re - study (c, d, e in Figure 1), after this section I will spend some time reviewing all the topics just to build the muscle memory as I believe this section has been mostly just facts and how devices operate, anyways lets get it into it! 

When automation is used in Cisco what manages it? The Cisco DNA Controller - its used as a way to manage networks along with the ability to be able to deploy a network in seconds, this is also a good technology to provide third party integration. The DNA controller is managed through a GUI web interface (This is similar to a MaaS server, if anyone has configured that!), in summary a DNA controller is used for management, automation and deployment. The entire DNA Center is a software, although with the word center it makes it sound like a physical attribute. 

A Wireless LAN Controller is similar to the Cisco DNA Center in that it is used to manage devices. When talking about a wireless LAN controller think of what devices are associated with wireless LANS! Access Points (AP's), a Wireless LAN Controller manages these access points, when talking about an AP it comes under one of the two categories: 
  • Autonomous Access Points - These are access points that dont need a WLC.
  • Lightweight Access Points - These are access points that are associated with a WLC.
WLC Features: 
  • Wireless Intrusion Prevention System.
  • Central policy & security management. 
  • QoS 
  • IPV6 Mobility & Security Management,

Python Crash Course Chapter 1-2! #1

 Hi Everyone,  As a continuation from my CCNA I have started studying towards my Cisco DevNet, to do this I need some prior knowledge with Python (which I dont have) so after doing some research I have found this book! I will be using this until I am comfortable with Python.  In the first two chapters I have learned how to create variables and assigned them values, along with this I have also learned how to use methods with the variables. These are some examples of me beginning my Python journey -  blog_message = "Hi everyone! My name is" name = "Iain" first_blog = "this is my first blog about Pyhton, enjoy!" day, month, year = 29, 11, 2020 print(f"{blog_message.title()} {name.upper()} {first_blog.title()} {day, month, year}") This is my first piece of coding, in this I got to use variables, methods and integers.

I PASSED! Cisco CCNA 200-301! Experience & Where I'm going from here!

 Hi Everyone, Long time no see. As the title says - I passed! After all the studying I have finally finished my CCNA on November 27th. So as a summary I managed to score 900/1000 - what do I think of the exam? I think that the exam focuses on a much wider spectrum than just R&S, I had an illusion in my head that most questions on the exam would revolve around R&S protocols when this wasn't the case at all! I had a majority of wireless questions is regards to WLC's, AP's etc (without going into to much detail - sorry guys blame the NDA) along with this there was other things that were involved that weren't on the blueprint which was mildly frustrating. My Advice? Learn all the gritty details, learn how to read routing tables things like longest prefix, AD, metric - what path will win? Learn protocol numbers, what the requirements for that protocol are to make a decision e.g how HSRP uses an active and standby router and how it decides what router is doing what. B

Python Notes #6 Functions

 Hi Everyone, Today I'm doing functions I have kept this as its own blog as this is a bit of a tougher topic and for my own memory I'd like to be able to find this easily if I ever had to review python notes. A function is a chunk of reusable code this means that the code can be created and then passed anywhere within the code later on. This is how a function works -  def name(first, last): print("Please enter name: ") print(f"Your name is: {first} {last}") name("Iain", "H") In this chunk of code I pass the parameters first & last within the function - from here I create a print statement asking for my name, notice how in the second print statement I am passing the parameters first and last (represented by the curly braces) and lastly I call the function name and define the values within the brackets - with the last statement now first will = 'Iain' and last will = 'H'. This code produces this output - Please enter
