Which command do you use to check the VLAN membership of an interface on a switch?

To determine the VLAN membership of an interface on a switch, the command that is commonly used is to show the details of the specific interface. This command provides comprehensive information, including the assigned VLANs, status of the interface, and other relevant configurations.

When you use the command associated with the interface (for example, show interfaces ge-0/0/1), it returns details about that interface, including which VLANs are associated with it. This is essential when troubleshooting connectivity issues or when configuring VLANs to ensure that the correct ports are assigned to the desired VLANs.

Other options do not provide a direct answer to checking an interface's VLAN membership in the same manner. For instance, while the command to show VLAN membership might suggest it could directly address the inquiry, it doesn't specify which interface is being checked. Commands that focus on general details or statuses may provide helpful information, but they won't hone in on the direct VLAN membership associated with a specific interface. Thus, showing the details of an interface directly is the most effective method.
