Okay.
So in this lab, we need to implement quality of service.
Let's have a look at rather one.
En route one Interpol sort of Cisco tops show run.
We can see some configuration on the router, but there is no quality of service configuration on the
router.
So as an example, on this interface, no service policy has been applied.
We don't see any class maps.
We don't see any policy maps on the router.
So confetti.
We told that we need to match a voice traffic using bar and specifically HTTP.
Let's create a class map.
And I'll use the name of voice.
Now you can specify match all or match any.
I'm not going to do that here.
But notice by default, match all is used.
In this example, we've only got a single match statement, so that won't make any difference.
So what are we going to match?
In this example, we want to match.
A protocol.
The protocol that we want to match is RTP.
So we want to match real time protocol.
By doing that, we are leveraging network based application recognition or NPR on the broader.
We now need to match HTTP traffic using end bar and we're going to set the DCP to a F 31.
Let's create another class map.
In this case, I'm going to match HTTP.
And again, I'm going to say match protocol http.
Next step is to match ICMP traffic using end bar.
So class map, ICMP, you could use any names here, but I'm simply going to match based on the protocol.
So I'm going to make the class the same as the protocol.
So as an example, I've created an HTTP class that's matching HTTP.
I've created an ICMP class that's matching ICMP, but I've used the word voice to match RTP.
You could use any descriptive name that you like for your class map.
Okay, so once we've created our class maps, the next thing we need to do is create a policy map,
and you need to give it a name.
I'm going to call this Mark in the exam.
Follow the names that you told to use.
But here we can use really any name that we want to.
We then need to match a class that exists so we can't just specify something like test.
The class map test doesn't exist.
We need to specify a class that we've created such as voice, and then we need to decide what to do
with the voice traffic that's matched.
We're told to set the DHCP to f, so set ip dhcp and notice.
Here's a list of dhcp values.
This is very nice because we can see both the name.
As well as the binary representation of the DHCP value we've been told to set a voice traffic to f,
so I'm going to specify f.
We also told to provide a priority notice the keyword priority bandwidth of 100 kilobits per second.
So in the class, that's part of the policy, I'm going to specify a priority bandwidth of 100 kilobits
per second.
So what have we created thus far?
We've got our class maps, we've created this policy, we matching the voice class, which is matching
real time protocol traffic.
In other words, voice traffic.
We're setting the DHCP to F.
And we providing a priority bandwidth of 100 kilobits per second.
So continuing policy, Marc Klaas, HDPE set DSP or in this case, IP, DCP to AF 31.
The minimum bandwidth that we're going to provide to HTTP is 50 kilobits per second.
We then need to specify our third class, which is ICMP.
Set IP DHCP to AF 11 bandwidth that will be allocated is 25 kilobits per second.
So we've created.
Our class maps.
We've created our policy.
The next step is to bind the policy on the interface.
So interface serial 010.
Service policy direction is output.
Policy name is Mark.
And there you go.
We've got our.
Closest configured.
We've got our policy map configured and we've bound the service policy outbound on serial 010.
I'll save the right of configuration.
So that's the configuration of right of one.
We now need to do something similar on router two.
