Startup Broker syntax : Require clarification

Hi Team
Understood from documents,that we use the below syntax for Broker start from command prompt
Windows/Unix – Broker\bin\broker_start –switch server[:port]

Can someone please help me in understanding each of these codea with an example
–switch
server
[:port]

Thanks in Advance

What is your wM version?

If you want to start broker server go to webMethods/Broker/bin. Run the below command giving your broker host and port details: We are calling a script (.sh) broker_start. To use this utility, the Broker Monitor must be running on the machine where the Broker Server resides.

broker_start hostName:portNum

Eg: broker_start localhost:6845

or

broker_start atlas.dev.mycompany.com:6845

Thanks for your response M@he$h
We are using the 7.1.2 version of webmethods

But I wanted to know the meaning of the syntax
–switch
server
[:port]

From which document did you find this command that uses -switch?

It was from a training documentation

so there is no such syntax?
