How to add vmnet10, 11, 12, 13...

Dear All,

I would like to configure a number of custom networks within VMware Server 2.0 and have noted that the VMware Server 2.0 User Guide states that up to 255 virtual switches can be added under Linux (p213). I take this to mean that I can have the standard vmnet0 to vmnet9 and vmnet10, 11, 12, 13, 14 etc. 

Firstly is this correct?

Secondly how can I create the additional virtual switches?

Thanks in advance.
