How do I add a label to the #> command prompt?

Question

I have a number of PortServer TS3 M units and I'd like to add a label to the #> prompt for each location they're in such as:
#LOCATION1>
#LOCATOIN2>
and so on.
So anyone logging in will know which site they're connected to.
I've gone through the docs and things I've tried have not worked...

Answer 1

Try set netlogins:

#> set netlogins cmdprompt=(new_prompt)

If you are setting this on a port rather than a network login:

#> set login cmdprompt=(new_prompt) range=(port_number)

Answer 2

I've tried a number of commands and the command prompt doesn't change.. see below:

#> set netlogins rootprompt="1632 Central"
#> set netlogins cmdprompt="1632 Central"
#> set netlogins premessage="1632 Central"
#>
Prompt didn't change

#> set netlogins cmdprompt="1632 Central"
#>
Prompt didn't change
