 Hi there welcome back to my YouTube. This is Daniel Rosel here. I want to just show a quick way to check if Fillover is working on your load balancing router if you set it up to manage failover now I did a whole video yesterday showing the networking setup. I rigged up. It's Slightly complicated involved adding three pieces of hardware on top of my ISP router now I've kept my ISP router because it's actually kind of hard to find a Non ISP router that has the right modem that'll work with my ISP. So for the sake of simplicity I've just kept that and on top of the ISP router. I have a Cellular router that's bringing in 4g connectivity to my network I also have the center piece of the network and it's just right there behind me is the load balancer I'm using the TP link TL R470 t plus It's a one of TP links older load balancers I went for it because my home internet is DSL so it's not very fast to begin with so I figured I'd get a kind of more basic piece of gear And when I finally get fiber optic I can then upgrade something more substantial then so I've got the load balancer and the ISP and the cellular go into that and then The networking happens on the LAN side of that including a access point For bringing out Wi-Fi to somebody who needs Wi-Fi in my house And I'm networked into the ethernet coming from that. So that's my setup and It's working beautifully, but you might you know be wondering the first week or two of operation Well, hang on. Is this thing actually doing anything or is it just passing through my ISP connectivity? If I'm going to the trouble of having a cellular router piped into that Is it actually failing over like how do you know it's working in a vertical commas for failover? So just a couple of ideas. I wanted to share Design to sort of thoughts on that so one way you can do it is there's a website called who is my ISP org and You can periodically just check that and make sure this is what I've been doing Because it's in its first ten days of operation Every six hours or so. I'm randomly just checking going on to who is my ISP And what I want to be seeing is that it's using for the most part my primary connectivity Now I've created a backup rule in the load balancer a simple backup rule if the primary fails Bring up the backup. So one one is the primary if one one is down bring up one two one two is cellular So I'm just doing spot checks to make sure that in the normal course of events I'm running on ISP and not on cellular now when it goes to cellular I can kind of tell because the internet gets a little bit slower It's not a massive difference, but I can notice it and sometimes I'll go on to that website just to verify now You could also log in to the embedded web server the EWS on the load balancer It's just easier to do it this way I find now the second way if you want to look at this a bit more big picture and say well In the course of the last 10 days for however long the hardware has been up How much cellular data has been used? Well, you can do that very easily So what you want to do is if you go into your TP links management interface on your load balancer This is what I have in the TLR470T. It's under status at the very very top left. There's this little Page that's labeled in the menu traffic statistics and just take a look at what I'm look at what look at what I'm seeing on my Screen here. So interfaces we have three we have LAN One one and one two now in my setup as I have it currently rigged up One one is the ISP line. That's the one coming From the router that's under that in a pass through connection as a bridge and one two is My cellular so that's the 4g that's being connected from a 4g router into the into the TP link As a backup connection source so LAN I don't really need to worry about what I can see here Is you can see for a second the cellular was just kicking in there with us with the low connection and now it's It's just gone down again. So tx and rx tx if you're into Microphones you already know this tx stands for transmission rx stands for receiver You often see that written on microphone pairs tx rx. So you're looking at the tx rate and the rx rate But really the data you're interested in is going to be the total tx bytes and the total rx bytes And really the total rx bytes the total rx rx bytes and I can actually sort on that Is how much data that interface has pulled down from the internet. So if you look here On one one we're seeing that I have downloaded 4 gigabytes since this clock started running and I've uploaded 570 gigabytes 571 now and that's my whole network everything on the network That's the total data used on either side and I compare that with one two, which is cellular backup By contrast, I've only downloaded This is one two here at the bottom of the table. I've only downloaded 14.8 megabytes and uploaded 2.4 therefore without taking out a calculator and doing the sums The the picture here is that 99 percent of the time or for the vast majority of time The load balancer is pulling and using from the cellular from the isp line and cellular There might have been a couple of momentary failover events that one two kicked in for But it's working as intended. So that's just a quick way to diagnose if you will Your load balancer to make sure if you're using it like I am For failover from a isp line and onto a cellular line Just so you can make sure that it's working I don't know go in and check that once once a week once a month Probably you want to do this more often at the start when you've just set things up like I have you want to make sure Everything's working properly together and the failover is happening Hope that video has been useful If you'd like to get more videos from me about everything related to home networking linux tech and other subjects Please feel free to subscribe to this youtube channel.
