what is the command to enable the web browser connection to a switch?

[Bernard_Morel]

I have one switch that I'm able to connect to web browser and others that I can't.

I'm looking for the command that should run in the others switch to enable the Browser connection.

Thanks

but not working for Summit 200-24, do you know the command for this model?
