In the package tracer lab.
You need to configure quality of service or quads or chaos.
In this lab, we're going to cover quality of service topics such as matching traffic, marking traffic,
doing something with the traffic, such as providing a minimum bandwidth guarantee.
Now, in the real world, you would follow a quality of service policy document.
In other words, you would decide which traffic types are important in your network and then allocate
bandwidth accordingly, or implement quality of service mechanisms such as policing, shaping, queuing
and others.
Based on your quality of service policy document in this lab, we're going to implement a basic quality
of service policy so that you can get familiar with class maps, policy maps, service policies and
other commands used for quality of service in Cisco environments.
On another one, you're going to match traffic using end bar or network based application recognition,
and then you're going to mark the traffic with DHCP values or differentiated services code point values.
In addition, you're going to use queuing on the egress interface.
In other words, on Serial 010 to prioritize voice traffic over other traffic types, voice traffic
will be in a priority queue.
HTTP and ICMP traffic will be given a minimum bandwidth guarantee.
You need to do configuration on both router one and rider two on router one.
You firstly need to match a traffic.
You need to match a voice traffic using end bar and specifically RTP traffic or real time protocol.
You need to set the DHCP to F for matched packets so you're going to match a voice traffic using end
bar and then mark the packets using DHCP and set the marking to expedite it forwarding.
Or if you need to match HTTP traffic using end bar and set the DHCP to AF 31 or should forwarding class
AF 31 ICMP traffic should be matched using end bar and you need to set the DHCP to AF 11.
When traffic leaves the router, you need to prioritize voice traffic, so you need to create an egress
or outbound quality of service policy on serial 010 that prioritizes voice traffic.
So we're going to configure a priority queue of 100 kilobits per second.
But in addition, you need to provide a minimum bandwidth of 50 kilobits per second to HTTP and 25 kilobits
per second to ICMP.
In other words, on this interface you're going to implement low latency queuing or priority queue cross
based waited for queuing.
Now don't worry too much about the figures used here.
This is a lab.
In the real world.
You would allocate specific figures based on your traffic types and the bandwidth you have available.
So as an example, if you had a gigabit interface or 100 megabits per second interface, you would adjust
a values accordingly.
In this lab, I simply want you to understand the mechanisms used for quality of service.
I want you to be able to configure and implement quality of service policies on routers and ensure that
you understand both the theory and practical side of quality of service.
Now on router to ingress or inbound on serial 020, you need to match voice traffic by matching dhcp
CEF and then you need to remark the traffic with an IP precedence of five.
You need to match HTTP traffic by matching DHCP 31 and then setting the IP precedence to three.
You should also match DHCP RF 11 and set the precedence to zero.
Again, see this as an exercise in learning how quality of service works and the mechanisms used for
best practices.
Have a look at Cisco documentation such as the quality of service solution Reference Network Design
Guide or R&D guide available on Cisco.
Com.
Again, you need to bind that policy inbound on serial 020 on router two now for verification.
Open up a browser on PC one and PC two and browse to Cisco dot com and Facebook.com.
In other words, on these PCs, browse to websites on the Internet and verify that you see matches in
your policy on both router one and router two.
Ping Cisco dot com from PC one and PC two and verify that you see matches in your policy.
Now, in this example, we haven't got an IP phone, so we won't be able to simulate IP traffic.
But by sending both HTTP and ICMP traffic, you'll be able to see matches in real time on your quality
of service policies.
Once you've done to that use simulation mode in packet tracer and send both ICMP and HTTP traffic into
the network and verify that you see the markings on the packets on both the serial interface as well
as the interface.
In other words, you should see that your HTTP traffic has a DHCP of a 31 on the serial interface and
IP precedence three on this Ethernet interface.
So can you complete this lab?
Download the attached packet, trace a file and see if you can complete the lab yourself.
Otherwise, watch the next video where I complete the lab.
