How to make a native vlan?
The report indicates a native VLAN mismatch on port 0/1 (number 99) and port 0/2 (number 1). It seems the configuration might not be aligning correctly.
In Cisco Packet Tracer the native VLAN was set but a mismatch error appeared. The system reported a CDP-4-NATIVE_VLAN_MISMATCH on port 0/3 and port 0/2. I resolved it using the commands: enable conf t interface vlan 99 ip address no shut exit interface FastEthernet 0/1 switchport trunk native vlan 99 no shut show interface trunk
Ensure the VLAN is configured correctly. You don’t have to establish an SVI on either side.
It means you need to configure something on both ends. You don’t have to set up a separate SVI on each side. The issue might be related to the native VLAN setup, even though you understand its purpose for network security. I sent over a job involving Cisco Packet Tracer where I configured VLANs and VTP on switches. I used a server switch and addressed other clients except switch 3. I followed the instructions but still faced problems. The native VLAN is meant to secure the network by preventing default VLAN 1, but I’m unsure why it isn’t working properly.
