Summary of "Cisco CCNA Packet Tracer Ultimate labs: Quality of Service (QoS) Lab. Answers Part 2"

Main Ideas and Concepts

QoS Configuration: The video demonstrates how to configure QoS on a router interface, specifically focusing on classifying and remarking different types of traffic (voice, HTTP, ICMP).
Class Maps and Policy Maps: The use of Class Maps to identify traffic types and Policy Maps to define actions for those classes is emphasized.
Traffic Matching and Precedence: The importance of matching traffic types and setting IP precedence values is discussed, with specific values assigned to different classes of traffic.
Verification of Configuration: The video shows how to verify that the QoS Configuration is functioning correctly by checking the policy map statistics and observing traffic matches.

Creating Class Maps:
- Define a class map for voice traffic: match IP DCP EF
- Define a class map for HTTP traffic: match IP DCP AF 31
- Define a class map for ICMP traffic: match IP DCP AF 11
Creating a Policy Map:
- Create a policy map called "remark".
- Set the precedence for voice traffic to 5 (can use either "critical" or "5").
- Set the precedence for HTTP traffic to 3.
- Set the precedence for ICMP traffic to 0 (routine).
Binding the Policy Map:
- Bind the policy map to the router interface (e.g., interface serial 0/0).
- Use the command: service-policy input remark.
Verifying Configuration:
- Use the command show policy-map interface to check the statistics and matches for the configured classes.
- Generate traffic (e.g., browsing websites or pinging) to see the matches increase for HTTP and ICMP traffic.

Initially, there are no matches for voice, HTTP, or ICMP traffic.
After generating HTTP traffic by accessing websites, matches for HTTP traffic increase significantly.
ICMP traffic matches are also recorded after performing ping tests.

The video features a single speaker who walks through the configuration and verification process in a Cisco Packet Tracer environment.

This summary encapsulates the key points and methodologies presented in the video regarding QoS Configuration in Cisco routers.
