You are an incredible instructor! I'm about to begin my 3rd quarter of ccna 7 class in college, and I WISH my instructor were as clear and methodical, detailed, and organized as you.
I got my ccna 9 years ago... And I didnt remember any command since now ... YOU ARE MAN ! Thanks a lot .. this videos make me remember everything ... keep with it ! nice videos nice explained.
Thank you. This makes so much more sense now. I have been using three basic wi-fi routers, and three unmanaged 24 port switches to separate my home network, my mail hosting network, and my web and cloud services with 3 separate IPs from my ISP. This will simplify things.
I was trying to recall part of the stuff I study when I took CCNA course back in 2004, along with these video series, everything working like a charm with Vlan & trunk
Hi Dan, Thank you for all of these great tutorials. I made a mistake inputting the trunk port info for the switch at port fa0/2. I forgot to add VLAN 1. It works now. I had to go back to video part 6 at marker 5:18 to review the settings. Thanks again
Amazing tutorials, can say enough how much those helped me. ive been reaching the web, downloading CBT Nuggets and ccna-on-demand video boot camps... these youtube tutorials given by Dan are clearly THE BEST. Thank You So Much!
man without these videos i don't think i would ever have understood how vlans work. but a quick question about this video. the way you set up the phones for VOIP and how you assigned them both a number, is that basically like an EXT? say if you work at a call center and want to call from your cubicle to your friend on the other side of the office, you just dial their assigned phone number to contact them? i hope you get what im trying to ask lol
Yes, you should be able to ping the router subinterfaces just like regular interfaces. Unless security firewall rules are blocking the communication. Can you communicate from VLAN to VLAN?
This series is awesome. Though CCNA 125 doesnt have a voice exam section, this is still good to know and have for when people wanting to take the voice exam of CCNA :)
150 is part of the network address if the subnet mask is 255.255.255.0 the network is the 192.168.150.0 network. Also 150 is in the third octet from left to right. They are called octets because each portion of the IPv4 address is 8 bits in length. That is why the numbers go up to 255, 8bits = 2 to the 8th power = 256 which starting at 0 is 0 to 255.
I wish you explained a bit more about the DHCP Raw Options since I never heard of that and am having some issues finding the information on google but that's my bad.
Dan thank you so much for all of this great videos. On this particular lab I did everything you did step by step, but my phone is not receiving DHCP ip address? I am wondering what I am doing wrong.
1- the router isn't set up as a dhcp server for the voip ip addresses 2- your phone is still part of the vlan that connects the other end devices. refer back to the bit where he mentions "no switchport mode access" in the switch console
I have a question. I was playing around with this lab afterward and seeing if I could ping between VLANs. I was able to successfully ping other VLANs from all VLANS except VLAN 1. I tried it from both PCs that were on VLAN 1. I also couldn't ping the gateway (192.168.1.1) from either of the PCs on VLAN 1. I double checked to make sure they have the right gateway address configured and they do. Strangely enough, I can ping 192.168.1.1 from the PCs on other VLANs. Any ideas?
It is because in the Router settings when he was making the sub interfaces for fa01/0.80 - he forgot to add Native after assigning the VLAN. Because VLAN 1 was the native VLAN number beforehand the router needs to know it has changed or it will still think VLAN 1 is the native VLAN and not VLAN 80.
150 is the option that defines the BOOTP address for the IP Phone in this instance, so that the phone knows where to load potential firmware updates etc.. from.
If youre still producing videos, would you please give a tutorial on how to connect an IP Phone and a PC end device on the same cable? on my icnd2 study it states i am able to do this, but cannot accomplish it in packet tracer. Is it possible using this program? Thank you for the series
This is all great and very easy to understand... My question is if you wanted to have the IP phone and the PC on one ethernet cable and you want them to still be on a seperate VLAN (and get a different IP address) could this be done, Instead of running 2 ethernet cables to an office (One for the phone and one for the pc ) ?
Shaun van Tonder Did you figure out if this works for what you asking or not? I am wondering the same thing now! would appreciate if you can answer if you figured it out!
Big Guy I didn't figure it out for the IP phone scenario but I did get Vlans working on our Wireless network here at College. So we have 2 Wireless SSID on one Wifi Access Point. One is a guest Network and one corporate network. The Guest SSID puts them on the Guest Netwoek Eg Vlan 4 and the corporate SSID puts users on the company network eg Vlan 10) I believe the phone is capable of doing this tho I am not sure how the config will look. ) You would basically create 2 vlans eg Vlan 10 (Users network) and Vlan 20 (Phone network) on all switches. And backbones between switches you would want to tag vlan 10 and 20 on those ports.. Then untag vlan 10 on all other switch ports and the phone would be able to tag voice traffic as Vlan 20 somehow... The switch would then separate the traffic and even give the computers different ips from the phones... This is how my wireless network is working anyway... So it def is possible.
All the video were great! I I have a question, the switch that doesn't have the ip phones, let's say I connect 2 ip phone to it with vlan switch porting 150 and allow trucking on that switch vlan 150.. Do I also need a router running dhcp in order for those new ip phones to work? Thx in advance
When you change the vlan setting in switch to voice vlan 150 ,, in the show vlan command the voip ports fa 0/20 n fa 0/21 are shown as part of vlan 1. why?
Thank You so much for your tutorial, have help me a lot for my class project. But I need help, I do everything and for some reason, the voip phones do not detect the numbers I programs. Can you help me here to figure it out why? Thank You.
What is your version of Packet Tracer? I have version 5 and can't get the VOIP commands on the router or on the phones. Where can I get an updated version? Thanks
I believe you are asking about the "option 150 ", and from what i understand option 150 is an special statement that allows the telephones to download and image from the router via tftp. and the ip -address- is the ip address of the router that has those images to download. Thats what i understand, maybe someone could confirm what im saying.
are you able to add only one ip source address? I have 3 IP phones all configured to separate VLANs with a router on a stick configuration? the IP source- address can only add one address. what can I do ? help, please!
only the end devices on vlan 50 are ping the router but other devices on different vlan are no ping the router. What might be the reason ?? Have assign all the vlans on the port on the switch towards the router. Also the switchport (towards the router) is in trunk mode. Could know what happen and how to rectify ??
hi Dan i follow everything you did and vlan 1 can communicate each other my ip phones working perfect all devices communicate each other except vlan 50 on each side, they won't reach each other i did it 2 times and i got the same result can you explain whats wrong thank you
Dan, I followed each step and my Iphone only shows configure IP....what did I do wrong? Regards interface FastEthernet0/20 switchport mode access switchport voice vlan 150
I ve not telephony services and ephone entry command on my router 2811, cisco ios 12.4 .Why not ? What i Have to do to enable VOIP services and command yet ?
Should I be able to ping the sub interfaces? I try to ping from 192.168.1.101 to sub interface 192.168.1.1 at the router. I am getting request time out
My ip phone don't work even aftersettings numbers.. but show run is showing following settings telephony-service no auto-reg-ephone max-ephones 10 max-dn 10 ip source-address 192.168.150.1 port 2000 auto assign 1 to 9 ! ephone-dn 1 number 12345 ! ephone-dn 2 number 12346
Hi Dan great lab! This is the message I am getting . Where have I gone wrong? Cheers %DHCPD-4-PING_CONFLICT: DHCP address conflict: server pinged 192.168.150.1. %DHCPD-4-PING_CONFLICT: DHCP address conflict: server pinged 192.168.150.2.
This series is hands down the absolute BEST I've seen so far.... The explanations are so clear...
Agreed!
Yes, totally agree
You are an incredible instructor! I'm about to begin my 3rd quarter of ccna 7 class in college, and I WISH my instructor were as clear and methodical, detailed, and organized as you.
If you have any questions Scott don't hesitate to ask: dan.alberghett(at)gmail(dot)com
These videos are the BEST I have seen. I have watched allot of technical explanations.... and this series is truly amazing! Thank you so much!!!
I got my ccna 9 years ago... And I didnt remember any command since now ... YOU ARE MAN ! Thanks a lot .. this videos make me remember everything ... keep with it ! nice videos nice explained.
@neutrino741 yes that would be my thinking too. thank you for spotting that

Dan your "quick tutorials" are actioned packed choc full of knowledge and experience that you share freeely open source, your some guy, thanks.
Well prepared and well presented, not in-your-face bellowing, Measured and unhurried, a pleasure to listen to, many thanks to a top-class educator!
One of the best videos ever seen on Cisco tutorial. Clean and simple. Great job done!!!!!!!
awesome. even after 11 years i try this . thanks

This is my first VOIP video I have seen, its soo cool
2018 watching these videos and learning a tonne. Makes it easy to learn really fast. Wish you would make some updated videos. Cheers.
wow! love it when you dialed the phone.. your instructions are so simple to understand.
This series is awesome.
Like your videos!
You're so direct with your explanations, and the examples you create aren't that complicated.
Kudos to you!
The series is superlative
Great lab for the newbies learning VOIP and DHCP in a safe environment.
Its an honour to learn from u Sir 😊
Thank you . This series was the best I have ever seen ... please make more videos

you made everything pretty easy ....your teaching skills is perfect , everything come clear
thank you
Really awesome explanation. I saw your complete video series on Vlan its the best.
This series is awesome. Though CCNA 125 doesnt have a voice exam section, this is still good to know and have for when people wanting to take the voice exam of CCNA :)
"Not exactly sure what I'm doing here", lol. Good tutorial man, very informative.

Many thanks for sharing. Well explained!!!
thanks for ur these great tutorials sir ......
Wow...Thank you so much!
Very informative
many thanks for the great tutorial. Do you have any videos on configuring Layer3 switches for VLANs? thanks again
no telephony-service command on router on my packet tracer, what seem to be the problem? great tutorial on VLAN and IP Phone configurations.
Dan you rock. That said, I don't have an option for telephony service on my 1841 router in packet tracer.
WHAT A SIMULATION SOFTWARE!!!!!! AMAZING!!!!
WHAT KIND OF SIMULATION CRAP !!!!!! :)
Hey Lee man
Was geht ab???
Wollten wir nicht mal nen Bier trinken gehen????
😕😠😬
Ja wollten wir, aber irgendwie meinte Nassim du musst oft früh aufstehen :P
Lass mal Sonntag oder so ...

Might be 8 years old at this point, but still a great video :-D

When you change the vlan setting in switch to voice vlan 150 ,, in the show vlan command the voip ports fa 0/20 n fa 0/21 are shown as part of vlan 1. why?
you haven't established it as part of the trunk protocol: 802.1q
Thanks for the video, easy to follow!
Great job.can we have more videos about ACL
@fiorellomannaia, probably you are using old version of Packet Tracer. Try version 5.3.3. you will find these options.
well done appreciate
Great video! very easy to follow. One question - What does option 150 ip 192.168.150.1 do?
Garry Sabino It specifies an IP address of the TFTP server where the firmware files for IP phones are stored.
Check on google for dhcp option 150 (tftp server). It is just a coincidence to have option 150 and Vlan 150
5:06 "I am not exactly sure what I am doing here" happens with me every time whenever I revisit my code 😆😆
you are awesome

How to configure the ip phones to communicate with other phones remotely, including the sub-interfaces in the configuration?
On phone1, you set the switchport mode to voice, but for phone2, you set switchport mode to access and it all still worked. Why?
do you have videos on catalyst switches , mpls ?
Hi
I'm unable to find the telephony-service mode
its only found in 2811 series lol
hi Dan i follow everything you did and vlan 1 can communicate each other my ip phones working perfect all devices communicate each other except vlan 50 on each side, they won't reach each other i did it 2 times and i got the same result can you explain whats wrong thank you
Somehow the 62001 was allocated to the second phone, while the 62002 was allocated to the first. Yet the result was very pleasant.
still a good tutorial...
problem is my phones dont register. they get a ip address but no line number
Great video...but until part 7 i got confius..hehe (VOIP) is look crazy.
2:58 - 3:01
"max-dialing numbers" or max-directory numbers?
jeebus this was useful
What about having a computer hooked up through the phone?
If there was a Domain controller that all pcs need to have access to for files/folders how would you do it?
+sunita regmi you can't do that in packet tracer you'll need GNS3
Dan, I followed each step and my Iphone only shows configure IP....what did I do wrong? Regards
interface FastEthernet0/20
switchport mode access

Around minute 5:05 of "not being sure" is not reassuring. VOIP phones does not acquire an IP address. Every command done correctly.
My ip phone don't work even aftersettings numbers.. but show run is showing following settings
telephony-service
no auto-reg-ephone
max-ephones 10
max-dn 10

auto assign 1 to 9
!
ephone-dn 1
number 12345
!
ephone-dn 2
number 12346
what if it does'nt give number to the phones ?
in order to understand why dan saying u have to take CCNA1 once u take that things make undestable
What is the name of the Software in the Video?
+Raja Ji Cisco Packet Tracer
too bad packet tracer 7.2 doesn't have telephony-service
Hi Dan great lab! This is the message I am getting . Where have I gone wrong? Cheers
