While working in a corporate environment as a network administrator, you notice that several devices are unable to communicate with each other despite being connected to what you believe is the same VLAN. What command can you execute to verify VLAN assignments and troubleshoot the issue?
The 'show vlan' command is used on network switches to display VLAN configurations and assignments. It helps in verifying which ports are assigned to specific VLANs, essential for troubleshooting connectivity issues between devices. The command outputs the VLAN IDs, names, and associated ports, providing a clear view of the VLAN landscape to determine if devices are correctly categorized.
