1
00:00:01,580 --> 00:00:03,510
He could also match on other values.

2
00:00:03,510 --> 00:00:14,400
So notice you could match on IP precedents and specify values such as 0 1 2 3 4 5 6 or 7.

3
00:00:14,450 --> 00:00:16,640
These values also have names.

4
00:00:16,730 --> 00:00:25,990
So as an example if I specify three here and then type two show run notice it shows up as three.

5
00:00:26,210 --> 00:00:29,180
But I could also specify flash.

6
00:00:29,750 --> 00:00:33,710
That's also a valid way to match.

7
00:00:33,710 --> 00:00:42,590
That's very similar to using port twenty three or the word telnet in an access list so you can either

8
00:00:42,590 --> 00:00:48,280
use the word or the number to specify the traffic that you're going to match on

9
00:00:52,240 --> 00:00:58,330
notice we also have a cause value that we can match on so we could specify a car's value of five.

10
00:00:58,330 --> 00:01:00,040
There are many other options available here.

11
00:01:00,040 --> 00:01:05,020
So match and let's say application.

12
00:01:05,020 --> 00:01:10,160
And here we can match on specific applications such as RTP or H3 2 3.

13
00:01:10,450 --> 00:01:18,570
We can use network based application recognition to match on higher level protocols so rather than just

14
00:01:18,570 --> 00:01:24,780
matching on layer two or layer three we could match on higher layers of the OSA model.

15
00:01:24,780 --> 00:01:32,840
We can also match NPL s values so we can match experimental values in the range 0 to 7.

16
00:01:33,470 --> 00:01:38,180
So as an example we could match experimental value 5.

17
00:01:38,200 --> 00:01:41,860
Now once you've matched on traffic you need to do something with it.

18
00:01:41,960 --> 00:01:50,400
So you either need to privatize it or rate limited or queue it or delay it or drop it as an example.

19
00:01:50,450 --> 00:01:54,840
And that's what some of the other mechanisms do on rudders and switches.

20
00:01:54,950 --> 00:02:01,370
Once you've classified or matched on traffic What are you going to do with that traffic as an example

21
00:02:01,370 --> 00:02:06,740
if you've got a first class boarding ticket you may go to the left door but if you've got an economy

22
00:02:06,740 --> 00:02:12,020
class ticket you go to the right door and you get a different quality of service and a different experience

23
00:02:12,500 --> 00:02:14,180
based on the ticket that you hold.
