In this example we will show one creative way to use notepad to set some very quick configurations and parameters. But your own creativity will show you additional ways to use notepad once you know a little bit about how the command line interface and notepad can work together. In this example, what we are going to do is we are going to open up the Ethernet 0 interface, and all of the serial interfaces on this particular router. We are not going to worry about the ISDN interfaces, but what I want to illustrate is that there are 5 different interfaces. And rather than having to go to each one and wait for it to come up, and all of things that we've done in the past in regards to opening up interfaces. All I want to do is, let's say I am just trying to discover my topology, and I want to find out what's connected to what. And so what I want to do is get all the interfaces open. Now there may not be anything connected to and I may find that out later on. But what I want to make sure of is that I don't have anything turned off that is of importance. And I want to do it very fast and in this case we only have 5. What if we had 15 or what if we had 50, we could still save tremendous amount of time using notepad. So what I am going to do is I am going to use my notepad tool. And I am starting off with just the names of the interfaces, for example interface s0, and no shut interface s1. And you notice that this notepad was one that I have used in the past to shut these interfaces. All I have to do is add the no, but if you didn't then you could type in on each of these the number of the interface and then what you want to do with that interface. And then interface Ethernet-0, same thing there, no shut. So no shut means open up. Now what I want to do is issue all those commands. So I am just going to copy it, so I just copy that information from the notepad, and now I am going to go into the command line interface. Now all of these commands have to be issued from global configuration mode. So all I have to do is go to global configuration mode one time. So I just type conf t, configure terminal that puts me in global configuration mode. Then right click on the cursor, click on paste. As you can see, all of those commands were put in and all of those interfaces are now changing their state. So now if I type end here and then 'i', then take a look at my interfaces, as we can see Ethernet-0 is up and serial-0, 1, 2, and 3 are assigned at least to up. Now we are going to find out that some of them don't have connections. But again that was just a very quick way to be able to make some very quick changes, or some very quick parameter changes. Another way I can use notepad would be to put in the login passwords that we talked about before. If they are going to be same for all the devices, why not put them on the notepad, and then just cut and paste them into each device. There is no sense in doing additional work. Sometimes you don't have time to do that, you got other things that you need to move on to. Especially in tests later on there might be timed tests, depending on how far you go down the track, and you'd definitely be using notepad more and more when time is also a factor. So I'd highly recommend getting used to cutting and pasting information from notepad. You will find that are tremendous advantages in using notepad. And that there are many different ways that you saw, your own creativity is the only limit as to what's possible in regards to using notepad. In our next chapter we are going to completely switch gears. And we are going to talk about a concept of being able to control access to interfaces and to certain protocols within an interface. And we control these using access lists. So in our next chapter we will discuss access lists. ] to interfaces and to certain protocols within an interface. And we control these using access lists. So in our next chapter we will discuss access lists.
