1 00:00:00,530 --> 00:00:06,460 The Cisco Iowa is a single file that a Rato will load into RAM when it boots up. 2 00:00:06,570 --> 00:00:17,310 Typically from flash in this example I've connected to an 18 41 router show flash shows us the operating 3 00:00:17,310 --> 00:00:27,760 system stored in flash show version shows us that this is the system file that the router is using. 4 00:00:27,810 --> 00:00:35,430 So the router loaded this image from flash into RAM and that's the operating system that the rod is 5 00:00:35,430 --> 00:00:37,110 currently using. 6 00:00:37,170 --> 00:00:44,520 Now every operating system has a file system that's used for the organization of files and operating 7 00:00:44,520 --> 00:00:51,750 system will typically store files in a fault system which includes directories and files within directories 8 00:00:52,290 --> 00:00:53,980 in Windows as an example. 9 00:00:54,000 --> 00:00:58,100 You use a backslash to indicate directories. 10 00:00:58,100 --> 00:01:03,840 So as an example in Windows you would ghoti see Colan backslash uses. 11 00:01:03,990 --> 00:01:13,290 DAVID In my example desktop to view files on the desktop Linux uses a forward slash for the directory 12 00:01:13,290 --> 00:01:20,410 structure on a router once again show flash shows us the flash Diyar or. 13 00:01:20,610 --> 00:01:22,950 Well so shows us the contents of flash. 14 00:01:22,950 --> 00:01:27,300 Notice flash and Ford slash. 15 00:01:27,330 --> 00:01:36,940 We also have the Mac directory option so we could create a directory called Test in Flash. 16 00:01:37,000 --> 00:01:43,900 So now when we use the Kamandi are we see this directory called taste which is very similar to what 17 00:01:43,900 --> 00:01:46,510 you typically find in Linux. 18 00:01:46,570 --> 00:01:55,570 I could then use the show running Komando Show running conflict command and I could pipe that. 19 00:01:55,710 --> 00:01:59,910 And in this case I could redirect the output to flash 20 00:02:02,470 --> 00:02:11,280 test and then let's push it to a file called Show run dot see if g. 21 00:02:11,290 --> 00:02:18,550 So now when I use the Kamandi are I see the directory test but I could use the command via our flash 22 00:02:19,420 --> 00:02:28,040 test and we can see the show run see if Chief file stored in that directory. 23 00:02:28,160 --> 00:02:34,340 Notice the show flash command not only shows me the root directory but in this case also shows me that 24 00:02:34,340 --> 00:02:44,990 file in this directory called test so I noticed Dhia are vs show flesh. 25 00:02:45,060 --> 00:02:48,690 So if you've used Linux this is very similar to Linux commands. 26 00:02:48,820 --> 00:02:54,200 Or if you've used C D in Windows it's very similar. 27 00:02:54,270 --> 00:03:03,640 We can read the contents of that fall by using the more command some more flash colon test Ford slash 28 00:03:04,760 --> 00:03:12,440 show run C of G and that actually reads the contents of the file in that directory. 29 00:03:13,490 --> 00:03:21,010 So the Cisco IOS provides a feature called the Cisco Iowas integrated file system or Cisco efface. 30 00:03:21,050 --> 00:03:26,680 This system allows you to create navigate and manipulate directories on a Cisco device. 31 00:03:26,740 --> 00:03:32,330 The directories that are available are dependent on the platform that you are using false systems that 32 00:03:32,330 --> 00:03:36,530 you'll come across include flash memory file contents as I've demonstrated. 33 00:03:36,530 --> 00:03:44,180 You also have network false systems such as TFT or trivial file transfer protocol RCP or remote copy 34 00:03:44,660 --> 00:03:52,090 and file transfer protocol or if DP You also have other places where you can write data such as in the 35 00:03:52,090 --> 00:04:00,020 RAM so a Cisco device could have a USP flash it could have flash memory on the motherboard. 36 00:04:00,020 --> 00:04:03,460 It could have RAM NV RAM and DP.
