CISCO for Lazy Persons

CLI Modes

Cisco CLI is a hierarchical structure. We  can work on various levels CLI. Every mode has its prompt. Thanks to that, we know where we are. Every mode possesses its own commands. We can write commands in command executive (EXEC), which we can call “EXEC Mode“.

A user writes a command, and it is checked if it’s correct. If correct, it’s executed. Information for a user is displayed about errors. We should see a “^” character showing us the place of the error. Due to  that, we can find the error easily.

EXEC Mode has two levels for security reasons: user EXEC mode and privileged EXEC mode. In the first mode, a user can only monitor CISCO devices. “>” is the prompt of this mode. In the second mode, we can administer our networks. “#” is the prompt. We can start a session in privileged EXEC mode in this way:

Poganin>enable

Poganin#?

    Today, I went to the beachfront with my children. I found a sea shell
    and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She
    placed the shell to her ear and screamed. There was a hermit crab inside and it
    pinched her ear. She never wants to go back! LoL I know this is completely
    off topic but I had to tell someone!

      Thank you. I simply have many things for sharing with others. Yes, you are right: I have more and more readers. I have a lot of posts to publish. If you wish to do business with me, please tell me. I’m afraid that it’s a trap. You know I must be careful. My potential is really huge. This is only a beginning. Only several days have passed since the start of my blog. I’m still developing my blog. Soon, I will have a lot of readers in the whole world. My English isn’t perfect, but I’m trying to improve it all the time.

    Hello would you mind sharing which blog platform you’re using? I’m planning to start my own blog in the
    near future but I’m having a hard time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I’m looking for something unique.
    P.S Sorry for being off-topic but I had to ask!

      Hello!
      OK. It’s WordPress. I tried Drupal, Joomla, and other frameworks. They are good for static websites, but a blog is a dynamic one. So WordPress is the technology you should be interested in. Very safe and with many options. I think it’s the best for your purposes. The more posts you publish the best position in Google you have. It’s automatic. WordPress is special designed for a dynamic content that is a blog.
      Please scroll down my blog to the very end, and when you look at the left-down corner, you’ll see: “Theme: Twenty Twelve. Blog at WordPress.com.” It’s clear. My blog should accept a lot of text, so I selected that theme. It’s light, clear, and without any things that are useless. Other themes weren’t good — they corrupted my text. So if you wish to select a theme for your blog, you should know what you are going to post first. In WordPress, you can choose a lot of themes (free or commercial). And then plug-ins and other thing that can make your blog unique.
      I’m a IT specialist, so my knowledge is huge about that topic. There are only a few tips for you. Best wishes!

      Do not worry — they will notice my website. First of all, this website should be useful for me. I can simply forget some commands.

      Never! I have another blog in Polish. Some posts to test WordPress. It is still working with no any problems. WordPress is a very secure technology. It can be hacked because you aren’t careful, Samuel. It’s good to place your WordPress blog on WordPress servers where my blog is. They are updating the technology all the time. The software shouldn’t be too old because it is to be hacked. They take care of that, not you. You will be forced to take care of that when you download and install the WordPress software on your own. yes, you can do that. You can place your Wordpess software on any hosting server. But nobody will take care of the condition of your blog. Only you! But you probably don’t want to do it. You have other things to do. So in this situation, my advice for you: place your blog on WordPress servers. Of course there are some restrictions. You can’t install plug-ins and other extensions, but you know my blog is safe. It really works. To have a WordPress blog on the WordPress servers go to the link:

      https://signup.wordpress.com/signup/

      Fill out the form and choose the mode: Basic, Premium, and Business. You are a businessman and you have money, so pick Business. You will have a lot of options to use. Some specialists will be taking care of your blog not to be hacked, and you will be sleeping well. With no fears.

      You should have a secure password using capitals letters, lower case letters, numbers and other symbols you have on your keyboard. They should be mixed, for example, sWt4&er#t2T. It should be longer than six characters. This password can’t be hacked. Write down such a password and keep it safe. Do not tell anybody or post in the Internet. It’s only your password.

      If you aren’t a specialist in IT, it’s the easiest way to go, Samuel. If you have any questions, feel free to contact me. Take care!
