Lab 8-4 Testing Mode: Overview
Lab 8-4 testing mode is a powerful tool used in network analysis and troubleshooting. It allows network administrators to examine and identify network traffic in detail, enabling them to diagnose and resolve network issues efficiently.
To enter testing mode, type “lab 8-4” at the command prompt. To exit testing mode, type “exit”.
Identifying TCP-IP Protocols
Lab 8-4 testing mode supports the identification of a wide range of TCP-IP protocols, including:
- HTTP (Hypertext Transfer Protocol)
- HTTPS (Secure Hypertext Transfer Protocol)
- FTP (File Transfer Protocol)
- SSH (Secure Shell)
- Telnet (Remote Login Protocol)
- SMTP (Simple Mail Transfer Protocol)
- DNS (Domain Name System)
- ICMP (Internet Control Message Protocol)
Each protocol serves a specific purpose and has its own unique characteristics.
Port Number Analysis
Lab 8-4 testing mode also allows for the analysis of port numbers. Port numbers are used to identify the specific service or application that is using a particular TCP or UDP port.
| Protocol | Port Number | Service |
|---|---|---|
| TCP | 21 | FTP |
| TCP | 22 | SSH |
| TCP | 80 | HTTP |
| UDP | 53 | DNS |
Well-known port numbers are assigned to commonly used services, such as web servers (port 80) and email servers (port 25). Dynamic and private port numbers are assigned dynamically by the operating system or used by applications for specific purposes.
Network Troubleshooting using Lab 8-4
Lab 8-4 testing mode can be used to troubleshoot a variety of network issues, including:
- Identifying network connectivity problems
- Diagnosing routing issues
- Troubleshooting application-specific network problems
