Summary of Cisco CCNA Packet Tracer Ultimate labs: Quality of Service (QoS) Lab. Answers Part 1

Main Ideas and Concepts

The video focuses on implementing Quality of Service (QoS) using Cisco's Packet Tracer, specifically within a lab environment. The speaker demonstrates how to configure QoS on routers to prioritize different types of traffic, such as voice, HTTP, and ICMP. The key concepts include:

• Quality of Service (QoS): A mechanism to manage network resources by prioritizing certain types of traffic over others.
• Class Maps: Used to define traffic types that need to be matched (e.g., voice, HTTP, ICMP).
• Policy Maps: Used to specify actions to be taken on the matched traffic classes.
• Differentiated Services Code Point (DSCP): A field in the IP header used for classifying and managing network traffic.

Methodology and Instructions

1. Check Current Configuration:
   • Access the router and use the command show run to view the current configuration.
2. Create Class Maps:
   • For voice traffic (RTP):
     • Command: class-map voice
     • Match protocol: RTP using n-bar.
   • For HTTP traffic:
     • Command: class-map HTTP
     • Match protocol: HTTP using n-bar.
   • For ICMP traffic:
     • Command: class-map ICMP
     • Match protocol: ICMP using n-bar.
3. Create Policy Maps:
   • Command: policy-map Mark
   • For voice traffic:
     • Match class: voice
     • Set DSCP: set ip dscp EF
     • Set priority bandwidth: priority 100 kbps.
   • For HTTP traffic:
     • Match class: HTTP
     • Set DSCP: set ip dscp AF 31
     • Minimum bandwidth: 50 kbps.
   • For ICMP traffic:
     • Match class: ICMP
     • Set DSCP: set ip dscp AF 11
     • Minimum bandwidth: 25 kbps.
4. Bind Policy to Interface:
   • Command: interface serial 0/1/0
   • Apply service policy: service-policy output Mark.
5. Save Configuration:
   • Ensure to save the router configuration after completing the setup.
