### Story Overview
In a typical enterprise network setup, switches are used to connect various devices and systems. The native VLAN plays a crucial role in ensuring that data is properly segmented and transmitted across the network. Understanding its function is vital for network administrators to maintain network security and efficiency.
### Plot Introduction
The story revolves around a network administrator, Alex, who is tasked with setting up a new network infrastructure. Alex must ensure that the native VLAN is correctly configured to prevent unauthorized data transmission and to maintain optimal network performance.
### Character Introduction
- **Alex**: A seasoned network administrator with extensive experience in network design and maintenance.
- **Sarah**: A junior network technician assisting Alex with the setup.
### Scene 1: Configuration Setup
Alex and Sarah begin by configuring the switch. They ensure that the native VLAN is set to VLAN 1, which is the default setting for most switches. They then proceed to configure the trunk ports to carry untagged traffic.
### Scene 2: Testing the Network
After the setup is complete, they perform a series of tests to verify that the native VLAN is functioning correctly. They use network monitoring tools to check for any unauthorized data transmission.
### Scene 3: Troubleshooting
In one of the tests, they discover that some untagged traffic is being sent to a non-native VLAN. Alex and Sarah trace the issue to a misconfiguration in the switch settings, and they correct it.
### Conclusion
The network is now set up with the native VLAN correctly configured. Alex and Sarah ensure that all untagged traffic is properly directed to the native VLAN, maintaining network security and performance.
