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.
