1 00:00:00,160 --> 00:00:06,900 In the section or don't talk about Io's emollients and the licensing first meal take over to the iOS 2 00:00:06,900 --> 00:00:08,410 system files management. 3 00:00:08,550 --> 00:00:13,370 And second we are going to take a look to the licensing procedure. 4 00:00:13,770 --> 00:00:21,050 First iOS system files management as you can see in the picture we have shown version command that we 5 00:00:21,050 --> 00:00:24,220 can display our iOS release. 6 00:00:24,470 --> 00:00:30,790 I also releases mamy to have the web to 15. 7 00:00:30,880 --> 00:00:39,900 Or if you want as you can see that you can display the version of iOS with charging comment and we hope 8 00:00:39,970 --> 00:00:49,790 also those two rings these trains are the bug fix and new features added version of the iOS releases. 9 00:00:50,830 --> 00:01:00,670 Let's take a look to the aisles 12 for this version of the iOS is considered as a mainline train and 10 00:01:01,110 --> 00:01:03,600 that takes mostly back fixes. 11 00:01:05,570 --> 00:01:17,910 And this version is associated with the technology train which adds Meum features to the iOS version. 12 00:01:18,060 --> 00:01:21,980 And here is the main line and the numbering of the iOS. 13 00:01:22,020 --> 00:01:31,720 So after four as you can see that three in number as you can see that we have three number who are the 14 00:01:31,720 --> 00:01:41,390 poor me a maintenance identifier and we have a train identifier and be able to identify areas where 15 00:01:43,320 --> 00:01:50,700 and here we have a three number again and we have a maintenance identifier and reboot identifier for 16 00:01:50,700 --> 00:01:54,090 the main line. 17 00:01:54,140 --> 00:01:57,090 And here the thing that zero train number in 18 00:01:59,920 --> 00:02:01,730 thing up zero. 19 00:02:02,790 --> 00:02:06,350 The first portion is showing us the major release. 20 00:02:06,480 --> 00:02:13,920 The second is showing us the minor really is the top portion is showing us the new feature really is 21 00:02:13,940 --> 00:02:16,210 number. 22 00:02:16,360 --> 00:02:21,120 This is means extensive maintenance really is the syntax temperamental and small is. 23 00:02:21,160 --> 00:02:29,650 And one of the maintenance rebuild number and if you take a look to the technology trend of this we 24 00:02:29,670 --> 00:02:36,800 are seeing a majorly Zammit minor release and new feature release number 10 standard maintenance release 25 00:02:37,160 --> 00:02:40,180 and the maintenance people number. 26 00:02:40,250 --> 00:02:50,750 It's the same process with the other end to display our image file name we're using short flash command 27 00:02:51,630 --> 00:02:52,500 as you can see the 28 00:02:55,270 --> 00:03:06,590 this is the are Cisco IOS in which finally that's about being put in. 29 00:03:06,620 --> 00:03:10,790 So let's take a look at the filename again. 30 00:03:11,290 --> 00:03:20,680 We have in the first portion we have a film showing our platform name which is 1841 for this version. 31 00:03:22,510 --> 00:03:26,450 And we have a feature set in the second field. 32 00:03:26,830 --> 00:03:28,330 This is IP Mazan here. 33 00:03:29,560 --> 00:03:37,040 We have an another field turf field in here which shows us the file format which is and zip from here. 34 00:03:38,610 --> 00:03:48,710 That shows us that's compris or Ziph and and is showing us that Rantzen REM forkfuls shows us the Worsham 35 00:03:48,710 --> 00:04:01,600 number and the last one is showing us the file extension that's been which means binary executable. 36 00:04:01,760 --> 00:04:11,420 So how we can take the backup of our iOS for redundancy is to be servers to keep the backup copy of 37 00:04:11,660 --> 00:04:18,870 our files and really we need to make sure that TFT server is available on our network. 38 00:04:18,880 --> 00:04:28,320 We know the test is using simple pink and we also make sure that the server has enough disk space 39 00:04:31,650 --> 00:04:33,330 and to return 40 00:04:36,670 --> 00:04:39,670 to take our eyes back from our AT&T work. 41 00:04:40,000 --> 00:04:46,210 We need to make sure that the server is available on network again and this time we have to make sure 42 00:04:46,210 --> 00:04:55,900 that if our rather has enough disk space or not we can use a TFT flash command to take our eyes back 43 00:04:55,900 --> 00:04:58,680 from our 50 p server. 44 00:05:00,700 --> 00:05:08,560 Sorry and we have a move system trying to move system is used to specify the system and manage that 45 00:05:08,650 --> 00:05:11,510 thing rather a lot at the start up. 46 00:05:11,560 --> 00:05:19,570 And as you can see that you you in various variations and in the second section we will talk about licensing 47 00:05:20,890 --> 00:05:29,490 to license our prologues first we need to buy a package or feature and receive a product activation 48 00:05:29,490 --> 00:05:32,040 key from Cisco. 49 00:05:32,040 --> 00:05:39,490 Second we need to open a license by Cisco license manager or Cisco license registration. 50 00:05:40,570 --> 00:05:48,150 And in the last minute they install the license to a device to violate license. 51 00:05:48,220 --> 00:05:56,810 We are using Schwalbe version comment again and we can see the info of our license because also you 52 00:05:56,810 --> 00:06:05,630 showed license all comments and check our license again two lessons back up. 53 00:06:05,650 --> 00:06:08,470 We are using license say command 54 00:06:11,590 --> 00:06:15,830 and to uninstall a license we are using these commands. 55 00:06:15,870 --> 00:06:22,350 First we need to disable the technology packet and then Nitta I stole the license as you can see that 56 00:06:22,380 --> 00:06:29,330 we are safe going first then we are clearing and removing license.
