1
00:00:00,980 --> 00:00:02,900
Falls can also be stored in Flash.

2
00:00:02,900 --> 00:00:10,550
So if I type the C'mon show flash I can see various files in Flash including the operating system of

3
00:00:10,550 --> 00:00:11,330
the router.

4
00:00:11,660 --> 00:00:20,080
I can then do the command copy run and pointed to flash.

5
00:00:20,480 --> 00:00:23,390
So let's call it run one dot see if G.

6
00:00:24,820 --> 00:00:33,970
Show flash noticed that file now exists in Flash more Flash run.

7
00:00:33,980 --> 00:00:38,360
Let's see if she will show me the file stored in Flash.

8
00:00:39,020 --> 00:00:48,380
So I was able to copy the running config to flash and also to view the contents of that file in Flash.

9
00:00:48,380 --> 00:00:53,660
So it's possible to store configuration files in Flash.

10
00:00:53,690 --> 00:01:00,740
I could also copy the startup config at the moment it's not set so save for the start of config by using

11
00:01:00,740 --> 00:01:01,540
the shortcut.

12
00:01:01,550 --> 00:01:02,840
C'mon W-r.

13
00:01:04,100 --> 00:01:15,910
And then I can say copy start to flash and I'll call the start one to see if G Show flash noticed stalked

14
00:01:15,910 --> 00:01:23,450
Let's see if G stored in Flash and I could view that by typing more flash start.

15
00:01:23,460 --> 00:01:28,380
See if G and I can view the configuration.

16
00:01:28,410 --> 00:01:36,180
Now another useful component is terminal length for type show run.

17
00:01:36,290 --> 00:01:43,620
I'll see the running config but it's restricted to a certain number of lines the default terminal length

18
00:01:43,920 --> 00:01:53,320
is set to 24 so once again when I top show run I'm told that there's more output

19
00:01:58,140 --> 00:02:04,170
will do that again and I press enter or see one line at a time.

20
00:02:04,310 --> 00:02:10,850
You can change the terminal length to vary the amount of output that you see.

21
00:02:10,870 --> 00:02:21,830
So as an example if I set it to five and top show run I only see five lines of output every time I press

22
00:02:21,960 --> 00:02:24,040
space ball.

23
00:02:24,040 --> 00:02:32,000
Now if you have a very long configuration a nice option to remember is terminal length 0.

24
00:02:32,350 --> 00:02:38,620
And now when I use the command show run it shows me the entire config rather than me having to press

25
00:02:38,630 --> 00:02:49,100
spacebar every time I get the full config in one go which is great when you want to do a copy and paste.

26
00:02:49,120 --> 00:02:57,280
So in this example I'm selecting the entire running config in one go which I could then paste into notepad

27
00:02:57,280 --> 00:02:58,420
as an example.

28
00:02:58,420 --> 00:03:06,370
So I've just taken the full configuration of the router and pasted it into notepad by selecting it in

29
00:03:06,370 --> 00:03:11,150
putty putty automatically copies any selected text.

30
00:03:11,350 --> 00:03:14,620
And when I right click it pastes it into the output.

31
00:03:14,980 --> 00:03:17,300
Now in this example I'm seeing another problem.

32
00:03:17,590 --> 00:03:25,990
When I enter the command and the rightest trying to resolve that using a DNS server and you'll notice

33
00:03:25,990 --> 00:03:29,650
it's taking a long time to do the resolution.

34
00:03:29,650 --> 00:03:37,930
So as an example if I typed Cisco dot com it's going to take it a long time to resolve that domain name

35
00:03:38,380 --> 00:03:41,970
no DNS server has been configured in the example.

36
00:03:42,310 --> 00:03:50,620
So the router is broadcasting on to the local segment to try and resolve the command or name that I've

37
00:03:50,620 --> 00:03:58,050
entered that can be very frustrating if you make a typing mistake because it takes a long time to resolve.

38
00:03:58,090 --> 00:04:04,420
So rather than typing configure I'm going to make a typo here and type it as follows.

39
00:04:05,710 --> 00:04:10,660
Notice with out the T and just the word configure with the typing mistake.

40
00:04:10,840 --> 00:04:12,290
I have to wait.

41
00:04:12,340 --> 00:04:18,820
So if you make configuration mistakes and you're not using a DNS server it can be very frustrating waiting

42
00:04:18,820 --> 00:04:20,580
for this to time out.

43
00:04:20,590 --> 00:04:28,250
So let's look at a resolution to stop this long delay in the timeout of the DNS name.

44
00:04:28,390 --> 00:04:32,160
So we're going to top confetti and type no IP domain

45
00:04:36,220 --> 00:04:39,280
and hit enter.

46
00:04:39,330 --> 00:04:46,540
Now if I type Cisco dot com so some command topped incorrectly notice.

47
00:04:46,570 --> 00:04:49,130
Now times out very quickly.

48
00:04:49,360 --> 00:04:56,500
Now if you're using a DNS server you could use IP domain lookup but in this example I'm not so I've

49
00:04:56,680 --> 00:05:05,200
disabled the lookup of domain names on the router to cause less stress and frustration with commotions

50
00:05:05,200 --> 00:05:07,310
taking a long time to time out.
