- Part 3 covers the different types of VLANs (Default, Data, Native, Management, Voice, and Blackhole), their function, and how to configure them.
The video uses Packet Tracer and is designed to accompany a Cisco CCNA 200-301 course of study.
Dan is excellent. We don't have classroom instruction, Dan is all the instruction one needs
This three part series was excellent, thank you.
Absolutely fantastic video.
I'm learning networking during my confinment... thanks!
Thanks alot. Sir you made my day. Best way to teach. 👍👍👍👍
Awesome, thanks D _educative videos and practical. God bless
Thank a lot sir.
Great video series, thanks a lot for your work. A questions if I may: I'm using TP-Link switches not Cisco and there's no native or black-hole vlan by default. Is it good practice to create them anyway? What's the point of making a black hole vlan and assigning ports to it if I'm gonna switch the ports off? Thanks.
I generally always create the Black-Hole VLAN for good practice and assign them to my ports that are in administratively down status because that way let's say your port was to be turned on, traffic won't be routed inbound/outbound of that port because it has a VLAN attached to it that literally goes nowhere, that is why it's called the Black-Hole.
Is this the last part? Where are the other parts ?
Where can I download the Packet tracer version you are using? thanks!
Genial for free

🤷♀️why not just shutdown the port in lieu of the black hole? Scenario I can think of a VoIP phone which has a switch port for the computer( voice vlan)As for the native vlan 1,why not just use the vlan 1 on the trunks and for each switch port explicitly set the vlan other than 1. Vlan 1 and 90 are both untagged 🤷♀️
It is recommended to not use VLAN1 as the Native VLAN mostly because of the default nature of VLAN1 I suppose and to prevent against VLAN hopping attacks I believe. Shutting down unused ports is recommended as well as moving them away from VLAN1
Yeah, the only thing I can think of is that when a new switch/malicious or otherwise gets introduced by default it would allow to communicate unless those ports aren’t in vlan 1 and that would incur a native vlan mismatch error but it’s a non issue because ports are presumed to be access nonnegotiate, black holed and/or shutdown.
good point
@danscourses Sir am preparing for CCNA.all the videos of yours helpful.Have you written any books?if so please suggest where could I find.
Hpradeep Hpradeep I mainly used two books , the official guide (Odom) and Lammle. Questions from buhagqir, few Udemy vids, packt books and videos, Kaplan, CZcams, Pluralsight, packet tracer labs, Pearson labs and a whole lotta cigars 😅. I took the ccent and then the ccna a yearish later - it was expiring. It’s the lab part I’d focus on, truthfully Odom is very verbose but he adds context when I wasn’t getting it with lammle, so I switched back and forth a bit. Lab, lab, lab. Truthfully I was excessive (always am) but I was crunched for time and needed to pass. For the CCNP I may do VIRL or a physical lab but packetracer should suffice and I can save up for that while I pursue other certs. Tip for labbing: setup your infrastructure as you have at work or create your own enterprise with multiple sites and hardware from scratch - this is where a physical lab and packettracer starts to show their deficiencies but will suffice for the CCNA, physical is good so you don’t look a like deer when you have to physically set one up (what do these lights do😅). How much do you want it and good luck.
