Hello and welcome to this lecture.
So now we have the H.A. class are up and running we see that the P.C. has internet connectivity.
So before we do the failover meaning that I will just shut down the first 48.
You should also see that for example I will access the CLIA on the on the active master.
So let's do this.
I want to show you basically something that's important.
So priority when the master is elected.
It's just one of the things that are taking into consideration but it's not the first one.
So if you want to know exactly.
So hopefully this year I start if you want to know exactly basically what was the reason for electing
one of the four the firewalls before that firewalls as master you would execute a command that you will
see just in a moment
so while waiting the CLIA council to start please know that the 48 VM running in in trial mode like
it is now has some limitations.
And one of them it's the speed the throughput the total throughput that that can go through it or flow.
So it's limited.
And when you're doing the labs you may experience latency so don't worry just wait.
But it will work.
So now let's say get system h a.
So high availability
status.
And here we say so master selected using.
So this this number is selected as master because we cannot see it so I will just put it in another
tab just click this button here
OK.
So now it's boarded up.
So it has here this sir Number is selected as the master because it has the largest value of override
priority.
And this one is selected as master because he's the only member in the cluster and you can see that
it's basically the same certain serial number.
So now we have the fourth gate up and running.
We have ping that's working as well.
So what we should do now is navigate to Janus tree.
So let's see the the forget firewall interface first I'll click on it.
Here is the master.
He is a slave.
And I will now just go to Janus three and on the 48 one which is the master.
I will just say stop
to 1.
It's stopping
and here is done.
So now let's go again to basically VM or workstation and Windows 10 and log in again.
So in the in the first in the first Tab 1 9 2 that once you say that 100 that 2 5 4 remember it was
48 dash one.
So admin click enter for log in and let us see the result.
Now
now here it is.
So 48 VM 64 and now it shows 48 Dash 2.
So this means that the failover was successful and now we have only one 48 firewall in the cluster.
It has it is synchronized it has priority 1 28 It is 48 Dash 2 again and has the role of master.
So if we navigate now to this to command prompt and they will do a control C let's take a look what
happened so I'm going up up up.
We have we have two packets here we could see some packets dropped like I know a couple of them three
or four.
No.
So basically yeah the fell over was more than successful.
We've seen we've seen I think two packets.
Yeah.
Two packets at one point and everything was just running like it should be.
So basically you can you can consider it as no packet loss if we now go on the front page we will try
to navigate to a different menu or something but anyway seeing the ping as successful it is already
we would proof that it is working.
So let's navigate now to something else
and let's go to let's say products.
So Internet is working.
It is successful.
Now if we also go back to 48 to
we see that it is the only one in the cluster.
It has the mass roll out no go.
I will.
I will now go back to the genius tree and power up.
This 48 dash one VM so start
48 1.
It's starting.
Let's look in the castle so this is 48 1
just to make sure it is right.
I will close it.
Go to Janus three right click click on console.
It will open a new one.
So I want to make sure that this console is in sync with the the power up process of the 48 firewall
here is.
So it's up and running.
Let's go back now to Windows 10 machine and I will click refresh.
Now let's uh let's log in.
So admin and hit enter
and here go.
So now the 40 gate one it's online again.
And when trying to navigate to the 2 5 4 IP address we see that we have landed again on 40 gate dash
one.
Now when the HP boots up we will see again that the 48 one it's the master and the second one with the
default priority of 128.
It's again slave.
So that'll be all for this session.
We have seen the failover as being successful the the land user the end P.C. basically did not lose
connectivity to the Internet and everything worked just as expected.
So really thank you for your time and see you in the next lecture.
