hmm. love this channel and that you are a god loving man but why do you say OUR when you talk about Jesus at the beginning? I'm Jewish so it's not really our...
There are plenty of Messianic Jews who believe as I do that Jesus is the Messaiah. He came first to the Jews, and then to the gentiles through His disciples, all of whom were devout Jews. Some of whom even persecuted the first Christians until they were shown the truth. I believe that Jesus is Lord of all. Even those who don't believe in God. God bless!
@@NetworkAdminLife I appreciate that is what you believe but when you say "our" it could rub someone who doesn't believe that Jesus is God the wrong way (Jews, Muslims, Atheists, Hindus, Buddhists, etc...) Just an FYI. You seem like a really genuine god fearing man so maybe you could say "my God Jesus who I believe is the God of all humanity." When you say "our" it feels like your kind of imposing your belief onto others and I'm sure that's not your intention. I love the channel by the way.
@@hw3748 When a witness testifies in court, is that witness imposing their beliefs on the court? I'm not forcing anyone to believe anything. I am testifying to what I believe. Simple as that. It is not my job to convince anyone of anything, only to testify to what I believe, and what I have experienced. Enabling belief in someone is the job of the Holy Spirit. Shalom!
G'mornin and Grace & Peace 2 u and your family brother! Thanks once again for another inflight video! I always enjoy when U take us up and report from the wild blue yonder!! As always i appreciate all that you do for us and have a great, safe and blessed day! God Bless!🙏🏽
We do now. I forgot to mention that in the video. MFA on remote access VPNs for everybody. Also we're implementing MFA for our servers. But that's not a network thing so I can't really speak to that. God bless!
Clarification: They have access in that they can do LDAP lookups (read only) as a function of normal authentication. There are other functions as well that requires users to be able to communicate with the DC's. God bless!
Most of my SFPs are LR. I'm actually wondering if the runs are too short in some cases. I think the bulk of my problems stem from us using OM4 fiber. God bless!
@@NetworkAdminLifei use om4 in most of my setups cause it’s one the cheapest and easy to get fibre , have you thought of trying some SR to see if the issue comes from having LR under 300m ? Maybe that the issue, try with one that is an issue and see if you can make it work if not replace it with a new LR sfp cause be the SFP all along causing the issue
Hey! Grace & Peace 2 U brother! Thanks 4 another great troubleshooting video!! I always love it when we get tours of the racks, even when there's an issue I'm always learning from your expertise! Thank 4 al that U do for us and the fun things you share! God Bless and have a great day!
Coming from SE and being well versed in tech. How would you recommend becoming a network admin? I'd like to be on the hardware side outside of robots and machines
So first of all I would teach myself to never look directly in a fiber, at short distances you won't notice anything, but when working with longer distances that can be bad for your eyes :) If you have really long fibers an OTDR meter would also be of great help, what it does is sent light over the cable and if it find like a break or something it will tell you at what length the break is so you know where to look :)
We know that some closets push the length limit for our OM4 installation. And I previously made a video on the cheap laser tracing tool I bought. But I got lazy on this one and haven't used it as a double check. Sometimes you can find faulty fiber runs just be seeing how much the laser light has diminished at the far end. Not by looking directly into the end, of course. God bless!
So making the assumption the other end of the fiber is also transmitting at around -1.44 dBm, you can account about a 0.3dB loss for every connection the light passes through, so with the patch panel in between that's 4 connections (2 SFPs and 2 bulk heads at the patch panel) / ~ 1.2 dB expected loss, and your receive power is at -2.77 dBm, so overall you're only seeing a loss of 1.33 dB which is pretty close to expected! Something I would do in this situation as I go through each rack is have a fiber click cleaner with me and just clean all the optical faces while I'm there, just to eliminate the chance a piece of dust might be part of the problem.
I agree definitely would keep a cleaner with me and im surprised you dont have a light meter to test it at each point its a must have when troubleshooting fiber, I work for a telco so i only work with SM.
That air handler was massive, I guess you are in one of those huge hospitals. I went to download "intermapper". Seems like they also sell "cuteftp" wow, I'm impressed that they are still around. But free trial of Intermapper is only 30 days. It will take me 30 days just to find time to try it so I will put that on a wish list.
Maybe before you walk away try your fiber loopback to see if port on your basement sw is working, if you dont have one , they are cheap on amazon and it will make you look even smarter. I bought one of each so I have a total kit. (I'm FE so I never know what I will run into) I once solved a VXLan with leaf and spine architecture in a massive 7 full cabinet storage system at 2am. The engineers might not have been impressed but I impressed myself. I feel smart just saying those above phrases. In addition there are no MAC addresses on the above systems. Each of the 48 sw ports is fiber channel with layer 3. Each port acts like a router (limited) The heat these systems give off is incredible. So cool, sorry I am reliving past events, now back to you.
I am a great fan of documentation. when working with fibre cleanliness is next to godliness. the clicker is your friend. I am not in any way religious, but you are free to go on as much as you like about it, it's your video and your channel. if vibration is a problem, or even a suspected problem, you can get the rubber isolation mounts for the racks, that will reduce or completely remove any vibration issues.
Always a pleasure watching your videos! I am in a position where I have to keep inventory(IP address, Windows, user details, monitor assigned to that user and so on) of more than 60 computers, over 30 printers and scanners and AP's and I am kind of "lost". I am trying all kind of methods to document everything in an excel file, all the network, in different sheets but doesn't really work the way I want. Could you make a video with how you documented you network in Excel? If you use is of course...Thank you in advance!
I could show you a template of what we used. It's nothing fancy. I don't want to expose my internal IP addresses so it will be just a template. God bless!
This is why its called computer science, you try a theory, sometimes it will work, other times it won't. If everything worked all the time, then there would be no need for IT people. Rebuilding the stack will allow you to test your next theory. It maybe the cable or the connection on the module.
I had a Ubiquiti switch do some stupid stuff before. However, it would have to run for a while and get up to operating temp, and then the POE would simply stop working. Nothing in the switch changed when I looked at logs or anything like that. I would restart and the POE would come back for a while. Replaced the switch and went to track down the issues with an Oscilloscope and found a bad capacitor and a bad filter. Cost me 1.00 to fix and about 30 man hours of downtime. I was not happy!
When I was at HP. I asked around to the guys who worked on the electronics to confirm what I heard about through the years. Simple is ground natural. I think that is the correct wording. Also on your issue. Yea, I hate that. When I first started in computers. (Mostly home computers.) Had it down to pretty much what caused an issue, how it was fixed and could re-produce it. I'm not saying it is not possible. But in some instances. Just (mostly for software.) you through a list at it and see if that cures the issues. Normally it does. As for your switch problem. As sated before can be a whole list of things. Firmware, os version, hardware revision of switch. A few years after I got into computers. I was building a school order. Did the old IDE hard drive as primary IDE and the CD-Rom drive as Secondary IDE. Both drives set to master. The CD-Rom drive did not work. Wed had like 30+ machines to build. I of course build a 2nd machine. Same issue. Then went through the list. Updates the bios and such. Talked to the mfgs. (Can't remember if I talked to all the mfgs.) If I changed the hdd to a different mfg it worked. If I changed the CD-Rom to a different mfg it works. If I put that same combo on master / salve on IDE it worked. So that is how we built them. The IT guy at the school was not impressed and came back said all machines from then on need to have the first configuration. So after that we started ordering in on large order 2 or 3 sample machines. Did all the setup and make sure it would work. Before ordering the rest of them. Anyway I hoped you enjoyed the story. TTFN. Oh and yes if you believe in the Lord that is great. Have a good day.
Problem is I have to move onto the next "thing" before I really get to dig deep into these kinds of things. If I stumble on a fix, that's good enough. I rarely care about the "whys". God bless!
I am guessing that traffic needs to be flowing between the stacking module to see the issue pop up. It also cannot be in the primary switch. I am not an Extreme user, but I would take a guess and say the memory utilization might have been Tx retries through that stacking port. Mgmt frames not getting through to the primary switch or something.
Good mornin and Grace & Peace 2 U and your family 2 day and Happy Father's day 2 U! Thanks once again 4 another great troubleshooting video! Wow if it's not the line card could it be the actual configuration? Maybe the duplex and speed are wonky. When all else fails, blow the switch away and reconfig from the ol trusty thumb drive Well I hope U have a great Father's day brother and I'll see U next week God willing! Take it easy and be blessed brother!🙏🏽
We have 6 PanOS firewalls managed by Panorama. We heavily use shared objects and policies where it makes sense. It’s a great tool for managing multiple firewalls. I’ll have to check with our resident Palo Alto expert if we ever changed the master key. I know we changed panorama’s VM IP address when we migrated it into another data center, but it was ok because we use DNS and our FW’s talk to Panorama by a name.
I *believe* that if you don't change the default master key then it just renews itself and there is no problem. It's just when you change the default. I could be wrong but that's what I understand. God bless!
Hey Grace & Peace 2 U and your family brother! Thanks a lot 4 this informative video this week! It seems the further I get in my cloud studies the more on-prem stuff arises that I have to think about! That's why I always learn from your videos b/c you always have a hands-on perspective for us! I appreciate all that U do 4 us and I'll catch U in the next one! God Bless! 🙏🏽
