In the section or don't talk about Io's emollients and the licensing first meal take over to the iOS
system files management.
And second we are going to take a look to the licensing procedure.
First iOS system files management as you can see in the picture we have shown version command that we
can display our iOS release.
I also releases mamy to have the web to 15.
Or if you want as you can see that you can display the version of iOS with charging comment and we hope
also those two rings these trains are the bug fix and new features added version of the iOS releases.
Let's take a look to the aisles 12 for this version of the iOS is considered as a mainline train and
that takes mostly back fixes.
And this version is associated with the technology train which adds Meum features to the iOS version.
And here is the main line and the numbering of the iOS.
So after four as you can see that three in number as you can see that we have three number who are the
poor me a maintenance identifier and we have a train identifier and be able to identify areas where
and here we have a three number again and we have a maintenance identifier and reboot identifier for
the main line.
And here the thing that zero train number in
thing up zero.
The first portion is showing us the major release.
The second is showing us the minor really is the top portion is showing us the new feature really is
number.
This is means extensive maintenance really is the syntax temperamental and small is.
And one of the maintenance rebuild number and if you take a look to the technology trend of this we
are seeing a majorly Zammit minor release and new feature release number 10 standard maintenance release
and the maintenance people number.
It's the same process with the other end to display our image file name we're using short flash command
as you can see the
this is the are Cisco IOS in which finally that's about being put in.
So let's take a look at the filename again.
We have in the first portion we have a film showing our platform name which is 1841 for this version.
And we have a feature set in the second field.
This is IP Mazan here.
We have an another field turf field in here which shows us the file format which is and zip from here.
That shows us that's compris or Ziph and and is showing us that Rantzen REM forkfuls shows us the Worsham
number and the last one is showing us the file extension that's been which means binary executable.
So how we can take the backup of our iOS for redundancy is to be servers to keep the backup copy of
our files and really we need to make sure that TFT server is available on our network.
We know the test is using simple pink and we also make sure that the server has enough disk space
and to return
to take our eyes back from our AT&T work.
We need to make sure that the server is available on network again and this time we have to make sure
that if our rather has enough disk space or not we can use a TFT flash command to take our eyes back
from our 50 p server.
Sorry and we have a move system trying to move system is used to specify the system and manage that
thing rather a lot at the start up.
And as you can see that you you in various variations and in the second section we will talk about licensing
to license our prologues first we need to buy a package or feature and receive a product activation
key from Cisco.
Second we need to open a license by Cisco license manager or Cisco license registration.
And in the last minute they install the license to a device to violate license.
We are using Schwalbe version comment again and we can see the info of our license because also you
showed license all comments and check our license again two lessons back up.
We are using license say command
and to uninstall a license we are using these commands.
First we need to disable the technology packet and then Nitta I stole the license as you can see that
we are safe going first then we are clearing and removing license.
