How can you verify the VLAN configuration on a switch?

Verifying the VLAN configuration on a switch is effectively accomplished by using the command "show vlan" in the switch CLI. This command provides a comprehensive overview of the VLANs configured on the switch, including details such as VLAN IDs, names, and ports assigned to each VLAN. It allows network administrators to quickly assess the VLAN setup and ensure that all configurations are correctly applied, which is essential for maintaining network segmentations and traffic management.

In contrast, displaying the switch's IP address configuration does not provide information related to VLANs; it focuses solely on the IP addressing scheme for management and routing, which is separate from VLAN assignments. Analyzing the switch's physical connections may offer insights into how devices are physically connected but does not detail the logical separation of traffic that VLANs provide. Similarly, reviewing the switch's performance metrics would yield data about traffic statistics and device performance rather than the specific VLAN configurations, leading to an incomplete understanding of the switch's VLAN setup.
