More videos like this please! Every time I lose my motivation to study, I always go back to your video A Day (night) in the life of a NOC Engineer. Thank you very much!
@bigmanpartey real on the job experience is vital, any that can be sought should be priority, CCNA teaches very limited scenarios not real world scenarios, again also my opinion. My experience has been based on hands on experience, not my qualifications. Quals work hand in hand. A CCNA does NOT make you an experienced network engineer by any means! Hands on does and more of
Wow, these are really amazing videos. It's really different from other networking videos because here I'm seeing how it's done in a real data center on a real rack. You guys are killin' it. Please keep those videos coming
Absolutely fantastic that you moved away from the noisy fans when explain things. Was a pleasure to listen and learn in peace so can stay focused. Also pretty good your looking for people with skills to do the job rather than a qualification. I really struggle with getting qualifications but have a very high iq and any job I have done in my life has always been done with pride and expertise. Every job can be broken Down into very small easy tasks. Once I had a job that required very complex math. However after a couple of days training I was doing the math as if I had done an A level in it. I can tell your company is a fine place to work. I could sit there all day making ethernet cables and be happy in that environment.
Haha - give him a break he's young and learning just like we had to once upon a time! Possibly invest your time advising how he could do things differently so he can learn from us. :)
Great video. Just a tip, you don't need to configure the ports to match the port-channel interface. just add ports to the port channel and they will inherit the configuration from the interface.
This is exactly the type of videos that i've been searching for on youtube for months upon months-- Actual configuration of actual switches. Can you continue to add to this series with more step-by-step configuration videos that take us beginning to end?? and it may be a lot of work but as you're doing so, could you even give us a diagram or even go back to the DC to the actual switches and point out exactly what ports are in question and how or why they're configured and linked and what intention is behind their particular configuration? from what i see, so far all we have is STP and portchannels configured with redundancy. whats next?!
Great video, but a little feedback: Not sure it was necessary to create a L3 interface for vlan 2 (using int vlan 2). To create a L2 vlan its just ”vlan 2” and then “name Internet” to give it a description. When showing the spanning tree states for the internet uplinks, the important column was the forwarding state for the uplinks, when both are up, one is in BLK mode, meaning it is not passing traffic, when the forward (root seen) interface is taken down then you see the other port become forwarding port. Would be good to show how you can influence which of the two switches has the preferred Uplink in forwarding.
You could've added interfaces to the port-channel first, and then modify settings of the channel. Both interfaces would be configured at the same time.
hi everyone my self akshay from India. I must say you your all videos are superup and also this one is fantastic. this is really cool and if you getting a chance to shoot more deep video so no worry about the viewer side we are enjoying a lot of your all videos. and also make troubleshooting videos of Syslog and port down etc. and I again say you all video are so cool and superb so please make the video for your loving audience and we really fun and enjoy your video because your video is so knowledgeable and helpful. being a network engineer sometimes I have seen this type of trouble so your video helps me out so thank you so much for the video and keep make it for us, please. and lot's of love for everyone
Hi guys, great your channel, I follow you and seen most of your videos and I love them, a greeting and hug from a distance from the end of the world Chile ...
Just found out how childish i am at 37, He said touch your rack and poke your rack and the other bloke's face didnt even move! that made me proper laugh out loud to the point my girilfriend said whats so funny, i showed her and she just said your so sad and walked out the room. Come on thats funny
How do you deal with failures (disk, server, router, switchs)? what software do you use to manage the infrastructure? what if one of the router/switches are configured on the wrong way (for example, without redundancy) can you catch that?
I was hoping we would see a little more configuration(maybe a part 3) showing you guys accessing the internet from those switches. I'm curious how you deliver access in the datacenter, do customers rent IP addresses and they just configure them statically on their equipment? Do customers announce their own BGP sessions? Thanks and I love the content!
BGP depends on what they are actually trying to do. Because how amazing Cloud VPS environments can be, the assignment of the IPs to a node from an switch which then is to the core router would probably be automated...
Even if not automated, I believe it's a lot up to the customers so it might be hard to show a specific case. They can do whatever they want with BGP and if you have your own AS, I think they can hook you up.
Kim Källén Hey -- could I get in touch with you? I actually want some help based on networking. Trying to solve a thing i wanted to do for over a month. If you help it will really be amazing :)
I love all the keyboard warriors commenting with their own two cents, and contributing their assessment on how Custodian does their business. If you consider yourself more knowledgeable than these guys, make your own YT channel, and contribute your information there.
I'm a CCNP, CCDP (no longer a recognized Cisco cert) and CCIP (no longer a recognized Cisco cert) and I find that over the years it's been less about networking and more about marketing Cisco's products and proprietary features. I'm leaning towards not renewing my certificates.
CCNA, CCNP and so on are relevant certifications to open doors in companies and actually learn about Networking. If You REALLY study CCNA/CCNPP are totally worth it... if You just cheat then, sure, everything loses a sense. It's not like certifications are bad, it's all about people and their approaches
very intresting. at my last workplace we had a noc team and network engineers which were separate, i always thought noc's are junior network engineers by default. there was also a datacenter team that was responsible for patches and failover.
Just a quick question, couldn't you configure just one switch and copy the confirmation onto the second switch to save repetition - after all, time is money...
Hi guys, Great video! Question I’m disabled I have about 30% use of my right hand. However I recently accepted a role as Data Center Technician. My question is can I work in a data center with one hand or does having a disability prevent me from doing the job? I would greatly appreciate you guys getting back to me!
It will be challenging. As installing equipment will surely need two hands, however, the use of server lifts and other tools will make it manageable! I wish you luck man! I do it quite often when on site for customers. I think you’ll make it work!
Hello guys. Got question, at the routers and switches do you use vrrp? I whant to make such a setup but im confuse if this require vrrp or i can do it with no vrrp. Thank you
I noticed the mac address for the root was the same for each internet uplink. Your edge device is this running some form of stacking technology for redundancy. Also do you offer bgp options instead?
19:48 on either switch...commands #switchport trunk allowed vlan1-50 and #switchport mode trunk are redundant.....apparently not neccesary to be both on portchannel 2 interface mode and the gi0/41-42 sub-range-interface mode......i do by executing both commands only on sub-range-interface mode...and enabling portchannel by channel-group 2 mode xyz
Great video, as usual! In fact, I'd like the longer explanation on why an ATS from a vendor such as APC would not be suitable to protect a dual feed customer with a single power supply from a power failures in your setup. I very much agree that a dual power supply switch/router should always be installed but we all know that there are customers with old equipment that you might need to keep on for a while and those might have single power supply :( The Cisco RPS option is nice but for certain environments, especially when running on pure Juniper or Extreme hardware, it might not be relevant
For starters, it's wires(possibly crossover) which connect different switches together. Then there's usually a SWD(switch distribution) and these are connected to routers(WAN). They connect to long distance routers(the internet)
I know ccna isn't all about Cisco iOS but also networking basics. My question is... In terms of data centres, is Cisco still king or do you also use other brand kit - ubiquiti, mikrotik etc
A diagram of how everything is connected and how the failover works would have been super helpful for people less experienced in the nitty-gritty of networking
I was working with some old 2960 switches working in Barcelona, and it was quite often i had to travel to switches and replace them. 4-5 a day o.O but they had been operative some 10+ years tho
Interesting things to note, use of 750W PSU in the RPS, not 1150, so that means none of your switches are using 1150 PSU as this would not be supported. Not completely true on requirement to reboot the switch, that depends on switch model, refer to Cisco Whitepaper, 3750E does not require a reboot, although I have no idea why you have shown a 3750X which does not support RPS DC connections, it uses Power Stack for redundancy. Equipment such as Catalyst series switch gear was never designed for DC environments in the first place, the fan design as you described is just one those examples of why.
@@kimkallen5594 well said. you can switch power on switches (device dependant) without reboot. It's also sad to see them not use a wrist strap... even cisco supply you with one. Very poor show from custodian with not 100% correct information. another reason why they WILL NEVER touch my networks, nor be recommended by me! i also wondered by incompatible products were shown together!
@@hanisirfan I work for a private company not a data centre. As a certified Cisco engineer; this is embarrassing to watch from a professional company. If this was an individual trying to help it wouldn’t be bad but for a data centre to broadcast this level of unprofessionalism and not to best practice advice is disgusting.
The largest servers(Or the most power-hungry) I've seen in DC's are GPU servers. Normally you could fit about 4 of these hosts into an entire rack, consisting of a head unit (a motherboard CPU, NIC's etc) which is then connected to the large JBOG below it (Just a bunch of GPU's....about maybe 8u in size). The JBOG itself consists of either GPU chips or large Nvidia graphic cards stacked. These monsters require a lot of power, about 5 PSU's in total for the entire host (1 PSU for 2 x GPU's & 1 PSU for the entire head unit). These are for customers who require a lot of number-crunching power got from the GPU's.
Can i ask? Can i plug the internet to the gigabit 48 ports on the switch and not on the uplink ports which contains 4 ports 10gb uplink? Then still connected to the internet?
Yes, you can put the router on any port you want. If your router doesn't support 10GB then there's no point in putting it on one of them anyway except to not use up one of the other 48 ports you have.
Hi, If I will be building a 3storey building and one of the requirement is a wireless connection to the data server. What is the step by step guide on making that data server.
1. Buy proper WiFi equipment). 2. Never ever put the server on the WiFi, just run cables 3. If you really need to have the server there - make sure you secure it 4. If you will ever have separate WiFi for guests - do some proper network segmentation
-I thought they used Spine-Leaf Network, with two switches in different Lans in the access layer then connect in separate lans for distribution \ core layer and then for the Routers in the Data Center, but it seems that the two Ciscos are connected on the same LAN and therefore the etherchannel \ portchannel with the two cables on the Gi0 / 41-42 of a switch to the other, are you using a single ISP in this rack? -Please I'm studying so if you don't mind, you can contact me so I can see a diagram of a rack of these two switches on the router or on the other layer above. -Interesting configuration of the Spanning Tree PVST + with rapid and vlan 2 to connect internet on the servers, placing the default vlan 1 up to 50 in the trunk. -And that out of the video you configured the first 3 vlans, ok the internet is the 2 the vlan 1 is the default what you put in 3? -Separam as administrative vlan? -If you are not bothering to answer me, it may be by email or message I would be very grateful ... !!! -Alias I'm scheduled for this month o Juniper JNCIA and the CCNA for the beginning of November, living here in Brazil wanting a job in Canada, USA or UK, more then 10 years of experience in a 24/7 control tower data center military environment, if you need it we are here too .... LOL
Not sure if they are ever actually doing spine-leaf as they are mainly talking about spanning tree but I'm mainly writing here so that it might push this question higher and help you! :)
@@kimkallen5594- In the videos it was clear that they use two switches in Spanning Tree PVST + protocol with rapid, thats ok this is ok, my doubt was in the layer above in the WAN connections because from what I understood of the connection they would not be able to use two ISPs for WAN, and which vlan was the management one. -They confirmed to me that they use only one ISP with 100% reliability and UP time (without Spine-leaf or Cisco HotStanby Router Protocol HSRP), and that the 3 vlans are an example but that the vlans from 1 to 50 in trunk are already configured . -They were very attentive and I took the doubt that I had. -Thank you...!!!!
@@educastellini And spanning tree is great for that setup so the customers should be fine :) And in their WAN routers they can do other things, like multihoming with multiple ISPs and multiple other things with BGP to separate their feeds. And from earlier videos we've already seen them connecting through mutiple ODFs and such so I think they do good job in that extent! Good to hear that you're happy and all the best to you!
@@kimkallen5594 --Actually Spanning Tree is a minimum prevention for network loops, when using servers that have almost always Dual or more NICs, both spanning tree is vital that it is enabled in the factory on Cisco switches, my question was related to them using all safeguards that Cisco technologies have provided for redundant connectivity and etc ... - It is not necessary to use BGP with the ISP ...?!?!?!? -Just two connections to different ISPs the cisco Hot Standby Router Protocol (HSRP), and ready two or more Routers inside the DataCenter and they will do the Wan redundancy and if Load-Balance is configured, only redundancy. -I worked in a military control center data center, and the military rule regarding redundancy is "who has 1 has none, who has 2 actually has one and so on", I try to work with 4 Wan options 2 in operation with Load-Balance and two in Spare Wan in Hot Stand By, and a lot of firewalls. -Their response is that we trust our ISP 100% and if it falls to them, it is their fault that we have no redundancy. -This I thought was very bad, if I were a client with a need for redundancy I would not co-treat what they showed, because any professional with CCNA like me knows what I am saying in this comment. -But they were very attentive I appreciate it.
Hey guys, I have send out my CV as i saw that you were looking for people on the website . I guess you would not accept me due to my location which is Bulgaria or my resume Never mind i just wanted to try at least :) wish you all the best and keep the good work.
Thanks, some questions. If I placed only a single server in your rack, do I still have to use your/my own switch? If I connect my single server directly to the red or green cable do I still need a firewall? How does my server become accesible to the outside world et: if running a web or mail sever? and the opposite, how do i close it to the outside world but only allow connection from my office lan? Cheers, these vids are helping me a lot to understand hosting, always thought about gettting some of my services hosted but never fully understood the topologies or connectivity.
You dont need a switch or firewall if you have 1 server. Most of the time you can just use iptables for firewalling or the datacenter has a simple firewall interface
Don't connect anything to the internet that is not "battle ready". So it's a great thing you're asking about firewalls and if you are hosting a web server, make sure to serve HTTPS with proper certificates etc. Custodian can probably help you with everything related to that. Just make sure you are not skipping on security due to cost - it will bite you later.
Why the heck somebody need DNA just to configure WAN uplinks ? Cisco is an expert just forces to use their product line which is not even needed in design cases and churn high prices on licensing
@@crazyboy2006cashier Is Custodian your competition or something? Do you also run a data center on the same block as these guys, and are here to throw shade on their obviously successful business, to benefit yours? Do you realize your stalking of their videos is actually helping them, and paying them?
@@davidm4814 No. I work for a large international company who manage our own datacentres. Being an IT professional, i just find it shocking the low level of standards shown by Custodian.
@@crazyboy2006cashier Oh, so you work for someone else. Well, if one day you're capable enough to run your own DC, you can implement the highest standards that you know. I'm sure you too, will be successful.
It's a way to bond multiple physical ports into a logical port, to gain redundancy in case of link failure. LACP is generally going to be what is used, if you want something to Google.
if you have small build You must use private vlan, if your build is big You must have factory or leaf spine connections this system is not a healthy system
Sir this is keshav from India mechanical engineer by seeing you videos I have decided that I will shift my entire career so please help me what are the basic steps I do to join data centers
Hey man, I am in the IT industry and personally work with servers. To get you started I would suggest getting a few certifications to help you understand computers a bit better. I started off by getting my CompTIA A+ and CompTIA network+, these are 2 very nice basic, entry-level certs that will give you a good foundation into IT. Try get an internship at an IT company who deals with servers so you can learn about servers in-person, that's how i did it.
Love when people in the comments tell people who work in datacenters how to do switch configuration for airflow
@hanis Irfan exactly my point
There's always a few ppl who just know better than anyone else 😆
😂😂😂
Imagine thinking the people that watch these don't already work in a DC... Why else would you watch these?
wkwkwk..

Where do you buy your cables and accessories like cable boots?
You guys do awesome content btw
Is port channel also called ether channel? In which you combine multiple physical ports to work as one.
Yep! Same thing. LACP, PaGP are the main protocols used. It gets a bit more complicated when working with MLAG or VPC in a data center though

Good information! Thanks
Please make some mattress for cabling jobs! Thanks
cisco sells its own ats designs which use atx looking connectors to the back of network appliances.
any future videos on routing and network structures. Would be great!
Would you not configure the switches before hand. .?
6:27 That's what she said.
Amazing video can you explain Telugu or otherwise please give discription on English what are you saying ❤️
So how much would a service like this be? Just curious of a rough estimate for setting up all this up.
How often do switch power supplies actually fail?
The failure rate is not zero. That's all that matters.
I was working with some old 2960 switches working in Barcelona, and it was quite often i had to travel to switches and replace them. 4-5 a day o.O but they had been operative some 10+ years tho
Not often, but they do fail. Extreme has failed on me and so has Juniper.
Do you have any Super Computer in the DataCenter? like a Cray..?
Been waiting for this.

@@hanisirfan I work for a private company not a data centre. As a certified Cisco engineer; this is embarrassing to watch from a professional company. If this was an individual trying to help it wouldn’t be bad but for a data centre to broadcast this level of unprofessionalism and not to best practice advice is disgusting.
@@hanisirfan this is like someone telling you how to wire up your house but using the wrong methods to do it
Or fitting rubber coated wire in 2020
Can you show us some really powerful server? I mean a beast of a server that normally you won't get to see.... Those you mostly only see in DCs....
The largest servers(Or the most power-hungry) I've seen in DC's are GPU servers. Normally you could fit about 4 of these hosts into an entire rack, consisting of a head unit (a motherboard CPU, NIC's etc) which is then connected to the large JBOG below it (Just a bunch of GPU's....about maybe 8u in size). The JBOG itself consists of either GPU chips or large Nvidia graphic cards stacked. These monsters require a lot of power, about 5 PSU's in total for the entire host (1 PSU for 2 x GPU's & 1 PSU for the entire head unit). These are for customers who require a lot of number-crunching power got from the GPU's.
@@jimmyfallon1890 how does a you do number crunching? Why r graphics cards used to crunch numbers and bit mine
Can i ask? Can i plug the internet to the gigabit 48 ports on the switch and not on the uplink ports which contains 4 ports 10gb uplink? Then still connected to the internet?
Yes, you can put the router on any port you want. If your router doesn't support 10GB then there's no point in putting it on one of them anyway except to not use up one of the other 48 ports you have.
can you please make a video on how to use loopgard in cisco ?
wr mem or do wr save the config
nice video.
you are amazing
How do you get paid by contracts , salary, or checks ?
Hi, If I will be building a 3storey building and one of the requirement is a wireless connection to the data server. What is the step by step guide on making that data server.
I dunno, wireless connection to few servers seems a b it unreliable
1. Buy proper WiFi equipment). 2. Never ever put the server on the WiFi, just run cables 3. If you really need to have the server there - make sure you secure it 4. If you will ever have separate WiFi for guests - do some proper network segmentation

Boi you know some networking 😛 wanna help me? 😛
-I thought they used Spine-Leaf Network, with two switches in different Lans in the access layer
then connect in separate lans for distribution \ core layer and then for the Routers in the Data Center, but it seems that the two Ciscos are connected on the same LAN and therefore the etherchannel \ portchannel with the two cables on the Gi0 / 41-42 of a switch to the other, are you using a single ISP in this rack?
-Please
I'm studying so if you don't mind, you can contact me so I can see a diagram of a rack of these two switches on the router or on the other layer above.
-Interesting configuration of the Spanning Tree PVST + with rapid and vlan 2 to connect internet on the servers, placing the default vlan 1 up to 50 in the trunk.
-And that out of the video you configured the first 3 vlans, ok the internet is the 2 the vlan 1 is the default what you put in 3?
-Separam as administrative vlan?
-If you are not bothering to answer me, it may be by email or message I would be very grateful ... !!!
-Alias I'm scheduled for this month o Juniper JNCIA and the CCNA for the beginning of November, living here in Brazil wanting a job in Canada, USA or UK, more then 10 years of experience in a 24/7 control tower data center military environment, if you need it we are here too .... LOL
Hmm, I wish I could answer these 😛
Not sure if they are ever actually doing spine-leaf as they are mainly talking about spanning tree but I'm mainly writing here so that it might push this question higher and help you! :)
@@kimkallen5594- In the videos it was clear that they use two switches in Spanning Tree PVST + protocol with rapid, thats ok this is ok, my doubt was in the layer above in the WAN connections because from what I understood of the connection they would not be able to use two ISPs for WAN, and which vlan was the management one.
-They confirmed to me that they use only one ISP with 100% reliability and UP time (without Spine-leaf or Cisco HotStanby Router Protocol HSRP), and that the 3 vlans are an example but that the vlans from 1 to 50 in trunk are already configured .
-They were very attentive and I took the doubt that I had.
-Thank you...!!!!
@@educastellini And spanning tree is great for that setup so the customers should be fine :) And in their WAN routers they can do other things, like multihoming with multiple ISPs and multiple other things with BGP to separate their feeds. And from earlier videos we've already seen them connecting through mutiple ODFs and such so I think they do good job in that extent! Good to hear that you're happy and all the best to you!
@@kimkallen5594 --Actually Spanning Tree is a minimum prevention for network loops, when using servers that have almost always Dual or more NICs, both spanning tree is vital that it is enabled in the factory on Cisco switches, my question was related to them using all safeguards that Cisco technologies have provided for redundant connectivity and etc ...
- It is not necessary to use BGP with the ISP ...?!?!?!?
-Just two connections to different ISPs the cisco Hot Standby Router Protocol (HSRP), and ready two or more Routers inside the DataCenter and they will do the Wan redundancy and if Load-Balance is configured, only redundancy.
-I worked in a military control center data center, and the military rule regarding redundancy is "who has 1 has none, who has 2 actually has one and so on", I try to work with 4 Wan options 2 in operation with Load-Balance and two in Spare Wan in Hot Stand By, and a lot of firewalls.
-Their response is that we trust our ISP 100% and if it falls to them, it is their fault that we have no redundancy.
-This I thought was very bad, if I were a client with a need for redundancy I would not co-treat what they showed, because any professional with CCNA like me knows what I am saying in this comment.
-But they were very attentive I appreciate it.
Hey guys,
I have send out my CV as i saw that you were looking for people on the website .
I guess you would not accept me due to my location which is Bulgaria or my resume
Never mind i just wanted to try at least :) wish you all the best and keep the good work.
Thanks, some questions. If I placed only a single server in your rack, do I still have to use your/my own switch? If I connect my single server directly to the red or green cable do I still need a firewall? How does my server become accesible to the outside world et: if running a web or mail sever? and the opposite, how do i close it to the outside world but only allow connection from my office lan?
Cheers, these vids are helping me a lot to understand hosting, always thought about gettting some of my services hosted but never fully understood the topologies or connectivity.
You dont need a switch or firewall if you have 1 server. Most of the time you can just use iptables for firewalling or the datacenter has a simple firewall interface
Don't connect anything to the internet that is not "battle ready". So it's a great thing you're asking about firewalls and if you are hosting a web server, make sure to serve HTTPS with proper certificates etc. Custodian can probably help you with everything related to that. Just make sure you are not skipping on security due to cost - it will bite you later.
can you show me how to configuration spanning tree 3 switch connecting between ? thank you
can we see how a customer's view?
You forgot to save the configuration on the switches! If they were to loose power all that work would be lost
Copy run start mate! Og, wr mem ofc xD
which is the command line, mate?
why u guyz use VMware as a hypervisor ?
For intalling VMs
You won't disclose what equipment you use on a huge free advertising platform.?
why you did not move to something like DNA for automation ???
because they use outdated logic.
Why the heck somebody need DNA just to configure WAN uplinks ? Cisco is an expert just forces to use their product line which is not even needed in design cases and churn high prices on licensing
@@crazyboy2006cashier Is Custodian your competition or something? Do you also run a data center on the same block as these guys, and are here to throw shade on their obviously successful business, to benefit yours? Do you realize your stalking of their videos is actually helping them, and paying them?
@@davidm4814 No. I work for a large international company who manage our own datacentres. Being an IT professional, i just find it shocking the low level of standards shown by Custodian.
@@crazyboy2006cashier Oh, so you work for someone else. Well, if one day you're capable enough to run your own DC, you can implement the highest standards that you know. I'm sure you too, will be successful.
❤❤❤
Your a CCNA Networking Admin sir
Sounds like Geico Green guy :D
what is this port channel thing?
It's a way to bond multiple physical ports into a logical port, to gain redundancy in case of link failure. LACP is generally going to be what is used, if you want something to Google.
if you have small build
You must use private vlan,
if your build is big
You must have factory or leaf spine connections
this system is not a healthy system
Sir this is keshav from India mechanical engineer by seeing you videos I have decided that I will shift my entire career so please help me what are the basic steps I do to join data centers
and you expect them to answer to a random user on youtube axaxaxax
Hey man, I am in the IT industry and personally work with servers. To get you started I would suggest getting a few certifications to help you understand computers a bit better. I started off by getting my CompTIA A+ and CompTIA network+, these are 2 very nice basic, entry-level certs that will give you a good foundation into IT. Try get an internship at an IT company who deals with servers so you can learn about servers in-person, that's how i did it.
Ok sir thank you for replay and for the information
Is there any server admin job
It's harry pater right there lol haha
Please discuss ats/sts pros and cons and use cases in next video!
