This command isn’t going to tell you the current active VLANs on your switch or give you a deep dive into the whole spanning tree protocol configuration.

Just to clarify again, that’s not to say those other commands are useless—they just have different roles. They're about different functionalities, and understanding that spectrum is what will elevate you as a network pro!

While we’re on the subject, think about how you might approach troubleshooting. It’s like having a toolbox, isn’t it? You wouldn’t reach for a hammer if you need a screwdriver.
