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.
Detailed Steps and Instructions
- 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
- Define a class map for voice traffic:
- 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.
- Bind the policy map to the router interface (e.g.,
- Verifying Configuration:
- Use the command
show policy-map interfaceto 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.
- Use the command
Observations During Verification
- 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.
