00:00:00,840 --> 00:00:07,800
The following videos showing you the integration between GNS3 and NPM are based on this how-to

2
00:00:07,800 --> 00:00:14,250
guide, which you can get from the below links. This may be useful to you after you've attended the training.

3
00:00:14,790 --> 00:00:22,260
So if you want to set up NPM and GNS3 refer back to this guide which contains a lot of information,

4
00:00:22,710 --> 00:00:28,470
including how to install both GNS3 and NPM, how to create the initial topology.

5
00:00:29,530 --> 00:00:37,270
The commands used on the routers, including commands such as setting up SNMP, setting up the IP addresses

6
00:00:37,870 --> 00:00:45,960
and configuring EIGRP, I'll also include the commands on the routers, on the relevant video in this

7
00:00:45,970 --> 00:00:46,480
training

8
00:00:47,470 --> 00:00:52,630
but you may find the integration going to be of benefit to you for reference later.

9
00:00:53,900 --> 00:01:00,020
In the next few videos, I'm going to show you how to build a topology within GNS3 that consists

10
00:01:00,020 --> 00:01:03,320
of three routers connected via serial interfaces.

11
00:01:04,390 --> 00:01:10,630
These are going to be the interfaces monitored by Network Performance Monitor. The three Cisco routers

12
00:01:10,630 --> 00:01:14,180
are connected to a switch, which in turn is connected to NPM.

13
00:01:14,800 --> 00:01:17,900
This is our out-of-band network management subnet.

14
00:01:18,580 --> 00:01:23,650
You don't need a dedicated network for management, but in this example, that's the way we're going

15
00:01:23,650 --> 00:01:25,510
to configure it. Now

16
00:01:25,510 --> 00:01:29,650
in GNS3 there are multiple ways to set up your Cisco routers.

17
00:01:30,400 --> 00:01:36,940
You can either run Cisco iOS routers directly within Windows using what's called the local server,

18
00:01:37,450 --> 00:01:42,280
or you can use a virtual box VMS or VMware VMS.

19
00:01:42,910 --> 00:01:44,680
It's up to you which method to use.

20
00:01:45,100 --> 00:01:53,110
The recommendation is that if you are only going to have Cisco routers and other basic devices such

21
00:01:53,110 --> 00:02:00,610
as the built-in Ethernet switches in GNS3 you can run GNS3 or locally on your local

22
00:02:00,610 --> 00:02:01,960
windows, PC or Mac.

23
00:02:02,470 --> 00:02:09,910
However, if you want to run more complex topologies using iOS layer 2 or other more complex setups,

24
00:02:10,060 --> 00:02:12,910
then you're going to want to use the GNS3 VM.

25
00:02:13,480 --> 00:02:19,960
Please refer to the GNS3 installation videos for more detail on how to set up and integrate

26
00:02:20,110 --> 00:02:20,950
GNS3.

27
00:02:22,240 --> 00:02:28,860
So in this example, I have a Windows 7 professional virtual machine running within a VMware workstation.

28
00:02:29,290 --> 00:02:36,400
I've allocated 4 gig of RAM to the 64 bit operating system and I've allocated 2 calls.

29
00:02:37,090 --> 00:02:44,170
So on the settings of a VMware workstation, you can see that 4 gig of RAM has been allocated.

30
00:02:45,620 --> 00:02:49,010
At the moment, only one process has been allocated.

31
00:02:49,760 --> 00:02:57,740
Now some recommendations from solar winds, you can run NPM on Windows 7, Windows 8.1

32
00:02:57,740 --> 00:02:58,910
and Windows 10.

33
00:02:59,390 --> 00:03:04,840
It suggested that you use 2 cores and 4 gigs of RAM as the bare minimum.

34
00:03:05,390 --> 00:03:12,320
It is better, however, to use 8 giga ram and 4 cores, but as a bare minimum use 2 cores

35
00:03:12,320 --> 00:03:13,700
and 4 gigs of RAM.

36
00:03:15,090 --> 00:03:21,120
So in this example, I'm going to shut down my virtual machine and I'm going to increase the amount

37
00:03:21,120 --> 00:03:28,800
of RAM and CPU so that it's a lot quicker when I do the demonstrations.

38
00:03:29,280 --> 00:03:32,640
Now, that's obviously dependent on what you have available

39
00:03:33,520 --> 00:03:43,240
on your PC, but I'll set it to use 4 processor cores and 8 gig of ram and I'll power on the virtual

40
00:03:43,240 --> 00:03:44,010
machine again.

41
00:03:45,580 --> 00:03:50,770
Now, something I always do, and this is up to you, but I always create snapshots

42
00:03:51,830 --> 00:03:54,800
of my virtual machines in case something goes wrong.

43
00:03:57,500 --> 00:04:05,330
So I've created a snapshot with, for example, a new install of Windows 7 with Chrome installed

44
00:04:05,780 --> 00:04:07,460
and that's where I am at the moment.

45
00:04:08,680 --> 00:04:12,040
Virtual machine is saying that I need to restart, so I'll do that here.

46
00:04:15,670 --> 00:04:23,590
So what I'm simply doing here is getting Windows 7 ready so that I can install NPM.

47
00:04:26,710 --> 00:04:35,800
You may also want to download Windows 2012, so as an example, you can download a VHD file and then

48
00:04:35,800 --> 00:04:42,730
import that into a virtual box if you want to run NPM on Windows Server 2012.
