VLAN Troubleshooting
XYZ Company is a very large retail chain in the Midwest United States. This company operates with a single corporate campus location and 25 regional distribution centers that support 3,000 retail locations. XYZ Company recently deployed a new switching environment using Virtual Local Area Network (VLAN) and Spanning Tree technology. The new switching environment includes redundant connections between each switch and includes the HR and Finance VLANs as shown below. Devices plugged into the HR VLAN on any switch require access to the HR VLANs across all switches. Devices plugged into the Finance VLAN require access to the Finance VLANs across all switches.
There have been multiple problems reported with the VLAN and Spanning Tree switching environment.
The new switching environment has exhibited the following problems:
Switch 1 HR VLAN communication cannot take place with Switch 2 HR VLAN
Switch 2 Finance VLAN cannot communicate with Switch 4 Finance VLAN
Switch 4 has both trunk ports to switch 3 continuously going from blocking to forwarding
