it's my third day of learning CCNA, but I'm on the DAY 8 Video. That tells how awesome this video course is. I hope you'll make another video course for CCNP may be. Your way of teaching and explaining complicated stuff is just uncomparable, I've tried many other video courses on Linkedin Learning and Udemy, nothing compares to this. Subscribed and followed.

[@seanturner7511]

Anybody else have issues with the "show interfaces description" command using Packet Tracer? I was able to enter a description for an interface like Jeremy did in the video, however I was unable to view the descriptions I'd made. I've tried doing it in global configuration mode with "do" in front, I've tried in privileged exec mode and I tried in user exec mode. It just keeps saying invalid input.

[@holla_academy]

Same here. It doesn't seem to work

[@sryksma]

in packet tracer, you can see the description using the "show interfaces status". And the description you just added will be displayed under the "name" column.

[@Moha-bi7xn]

Same for me, I think Packet Tracer removed it, otherwise you can see the descriptions in the configuration file with the 'show running-config' command

I'm having a hard time understanding why the graphic at 8:30 is showing three separate networks. At home, if I connect 3 different switches to my router, the switches (and their connected clients) are still part of the same network and will all receive IPs in the same range. This applies in a business setting too...many switches are connected to the router and all the devices on those each of those switches are part of the same network. I guess I'm confused about where a LAN starts and stops and the more I google it, the more confused I am. 😥

[@abdelrahmanelsherbiny8833]

What if I configure a network within class C (range 192 - 223), let's say for example 192.168.0.0, however instead of configuring it with network prefix /24 (as per class C standard), I configure it with network prefix /16. Would it still be considered a class C network, or changing the network prefix would also change its class to class B?

[@JeremysITLab]

The classes are determined by the range of the first octet, so it would still be class C. However, you aren't free to assign whatever IP addresses you want, if your company is assigned a class C network (/24), but you decide to configure a /16, your network will overlap with any other network beginning with 192.168 and you will be in violation of your contract with the IANA (Internet Assigned Numbers Authority). Now, there are private IP address ranges that you are free to use only within your internal network (actually, 192.168 is one of those ranges, so in this case you would be safe), but I will cover those later in the course.
