1
00:00:00,500 --> 00:00:03,566
Oh, shit.

2
00:00:06,166 --> 00:00:09,633
In this video, we want to take a look
at a way to manage our network

3
00:00:09,633 --> 00:00:12,633
using a graphical
and a programing interface.

4
00:00:12,633 --> 00:00:14,966
It's called Cisco Catalyst, a center.

5
00:00:14,966 --> 00:00:19,133
That's the new name for Cisco DNA center,
and you're likely to encounter that term

6
00:00:19,133 --> 00:00:23,066
a lot in much of the literature out there,
and even some of the configuration

7
00:00:23,066 --> 00:00:27,333
screens of a Cisco Catalyst Center
still, say Cisco DNA center.

8
00:00:27,366 --> 00:00:30,333
So whenever you hear the term 
Cisco DNA center,

9
00:00:30,333 --> 00:00:33,433
think Cisco Catalyst Center and Cisco

10
00:00:33,433 --> 00:00:37,333
Catalyst Center, that's an appliance
that we can install in the network.

11
00:00:37,466 --> 00:00:40,933
Or there's also an option of running
a Cisco Catalyst Center in the cloud.

12
00:00:41,100 --> 00:00:43,200
But this is going to give us
a graphical interface

13
00:00:43,200 --> 00:00:47,466
and also a programing interface
to design our network, to add devices,

14
00:00:47,466 --> 00:00:51,033
to configure devices, to monitor
the network, to troubleshoot our network.

15
00:00:51,300 --> 00:00:52,733
And I know Cisco in the past

16
00:00:52,733 --> 00:00:56,433
has had several other graphical front ends
for router configuration.

17
00:00:56,766 --> 00:01:00,133
They used to have the Cisco Configuration
Professional,

18
00:01:00,433 --> 00:01:04,966
but Cisco Catalyst Center is way beyond
that in the scope of what it can do.

19
00:01:05,200 --> 00:01:05,900
Let's take a look

20
00:01:05,900 --> 00:01:10,033
specifically at some of the main areas
that Cisco Catalyst Center focuses on.

21
00:01:10,300 --> 00:01:12,300
And first up is design.

22
00:01:12,300 --> 00:01:16,500
With design we can take a map of the world
and we can add an area.

23
00:01:16,500 --> 00:01:19,366
And we can say within this area
we have a building

24
00:01:19,366 --> 00:01:22,266
or maybe there's another area
within this area.

25
00:01:22,266 --> 00:01:24,833
We can import a floor plan into a building

26
00:01:24,833 --> 00:01:27,466
and drag
and drop our devices on that floor plan.

27
00:01:27,466 --> 00:01:30,266
And we can say what our IP address
allocation is.

28
00:01:30,266 --> 00:01:34,200
This is a way for us to design our network
through a graphical interface.

29
00:01:34,566 --> 00:01:38,433
And in addition to that,
Cisco Catalyst Center can apply policy.

30
00:01:38,633 --> 00:01:42,333
We can assign policies to an entire group,
maybe allowing them

31
00:01:42,333 --> 00:01:44,266
or denying them access to something.

32
00:01:44,266 --> 00:01:46,700
We can do IP based access control.

33
00:01:46,700 --> 00:01:49,700
And one of my favorites
is QoS quality of service.

34
00:01:49,866 --> 00:01:52,800
For example,
we can set up a queuing profile to say

35
00:01:52,800 --> 00:01:55,800
what bandwidth amounts
are given to different applications.

36
00:01:56,100 --> 00:01:59,333
We can also do provisioning
with Cisco Catalyst Center.

37
00:01:59,566 --> 00:02:02,266
We can essentially do plug and play
for a new device.

38
00:02:02,266 --> 00:02:06,366
For example, we could have a new network
device sent to whatever location

39
00:02:06,366 --> 00:02:09,366
that it's going to be installed,
have somebody plug it in,

40
00:02:09,633 --> 00:02:13,133
and when that device boots up,
it can go out and get some IP address

41
00:02:13,133 --> 00:02:17,866
information from a Dhcp server,
including DNS server information.

42
00:02:18,166 --> 00:02:22,266
And it's going to resolve the IP address
of a Cisco Catalyst Center server.

43
00:02:22,566 --> 00:02:26,100
And from that server,
based on the device's serial number,

44
00:02:26,200 --> 00:02:29,000
it's going to be able
to download its configuration.

45
00:02:29,000 --> 00:02:32,200
Sometimes you hear that
called zero touch provisioning.

46
00:02:32,233 --> 00:02:36,300
We just set up a profile for that device
within Cisco Catalyst Center,

47
00:02:36,566 --> 00:02:39,600
and somebody has to plug it in
and it installs itself.

48
00:02:39,900 --> 00:02:42,933
Another big part of Cisco
Catalyst Center is assurance.

49
00:02:43,200 --> 00:02:46,000
This is where we can monitor
the health of a network.

50
00:02:46,000 --> 00:02:49,133
And it's going to help us tremendously
when it comes to troubleshooting.

51
00:02:49,333 --> 00:02:52,733
As one example, we can do something
called network time travel.

52
00:02:52,900 --> 00:02:56,500
So if there was some sort of an issue
that came up at maybe 2 a.m.

53
00:02:56,500 --> 00:02:59,600
last night,
we could go back in time virtually

54
00:02:59,700 --> 00:03:03,100
to see what was going on in the network
at that particular time.

55
00:03:03,366 --> 00:03:06,366
And one of the most powerful things
about Cisco Catalyst Center

56
00:03:06,633 --> 00:03:09,933
is its ability
to act as a programing platform.

57
00:03:10,100 --> 00:03:15,000
It comes with a huge collection
of APIs, application programing interfaces

58
00:03:15,200 --> 00:03:18,000
that allow us to program
a certain configuration

59
00:03:18,000 --> 00:03:20,933
instead of doing it
manually through a graphical interface.

60
00:03:20,933 --> 00:03:22,500
We can do it programmatically.

61
00:03:22,500 --> 00:03:24,700
For example,
if we want to do provisioning,

62
00:03:24,700 --> 00:03:28,766
we can do that with a Python script
using some of these APIs.

63
00:03:29,166 --> 00:03:33,066
Obviously Cisco Catalyst Center,
it is a very robust platform,

64
00:03:33,233 --> 00:03:36,966
and you could go through weeks of training
just on Cisco Catalyst Center.

65
00:03:37,333 --> 00:03:38,866
But just to give you a sense for it,

66
00:03:38,866 --> 00:03:41,866
let's go out to a live interface
and look through a few of the menus.

67
00:03:42,166 --> 00:03:46,266
And by the way, as a comparison,
you might have heard of Cisco Epic.

68
00:03:46,500 --> 00:03:49,700
That's an application policy
infrastructure controller.

69
00:03:49,933 --> 00:03:54,766
And the Cisco Epic is Cisco's management
platform for data centers.

70
00:03:54,933 --> 00:03:57,400
Well, think of Cisco Catalyst Center

71
00:03:57,400 --> 00:04:00,766
as Cisco's management
platform for enterprise networks.

72
00:04:00,966 --> 00:04:03,900
So again, think Apic for the data center

73
00:04:03,900 --> 00:04:06,900
and think Cisco Catalyst Center
for the enterprise.

74
00:04:07,200 --> 00:04:10,033
Now let's take a look
at Cisco Catalyst Center in action.

75
00:04:10,033 --> 00:04:11,900
Let's go ahead and get logged in.

76
00:04:11,900 --> 00:04:15,733
And notice that the branding
is still shows as Cisco DNA center.

77
00:04:16,233 --> 00:04:20,100
And now that we're logged in
let's go up to our little hamburger menu.

78
00:04:20,100 --> 00:04:22,800
And we notice we've got those areas
that we talked about earlier.

79
00:04:22,800 --> 00:04:27,066
We've got design policy provision
assurance platform.

80
00:04:27,333 --> 00:04:30,433
Let's go under design
and take a look at this existing

81
00:04:30,433 --> 00:04:34,166
network hierarchy in this sample
Cisco Catalyst Center server.

82
00:04:34,333 --> 00:04:36,600
And notice
we're looking at a map of San Jose.

83
00:04:36,600 --> 00:04:38,600
And we can see Cisco's headquarters.

84
00:04:38,600 --> 00:04:41,333
And we can zoom
in on a particular building.

85
00:04:41,333 --> 00:04:44,100
And I can say I want to view
devices within that building.

86
00:04:45,700 --> 00:04:48,166
Let's click on unassigned devices.

87
00:04:48,166 --> 00:04:51,166
We could go in to switch to.

88
00:04:52,333 --> 00:04:55,333
And here we can see information
about our Ethernet port states.

89
00:04:55,633 --> 00:04:58,300
And one of my favorite things
is configuration.

90
00:04:58,300 --> 00:05:02,100
You can actually see the Cisco
iOS configuration for this switch.

91
00:05:03,266 --> 00:05:05,100
Now let's take a look under policy.

92
00:05:05,100 --> 00:05:08,100
We'll open up
that new and go under policy.

93
00:05:08,500 --> 00:05:11,800
This time let's say application
shows for quality of service.

94
00:05:12,066 --> 00:05:13,766
And let's go into queuing profiles.

95
00:05:13,766 --> 00:05:15,800
This is what I was discussing earlier.

96
00:05:15,800 --> 00:05:18,666
And notice that we have different
bandwidth percentages

97
00:05:18,666 --> 00:05:21,300
that have been allocated
for different classes of traffic.

98
00:05:21,300 --> 00:05:24,133
Multimedia streaming for example
that gets 10%

99
00:05:24,133 --> 00:05:27,133
real time interactive gets 13%, and so on.

100
00:05:27,366 --> 00:05:30,366
And that's an overview of Cisco Catalyst
Center.

101
00:05:30,400 --> 00:05:34,100
Cisco's graphical management interface
for enterprise networks

102
00:05:34,400 --> 00:05:35,833
and not just graphical.

103
00:05:35,833 --> 00:05:39,266
It can also be used
to program with those APIs.
