nas table and virtual servers?

Does the nas table work with virtual servers? That is, what is the nas configuration equivalent of the following config? client my_switch { ipaddr = 192.168.201.154 secret = abc.123 virtual_server = my_virtual_server } On startup, freeradius reads from the nas table and loads the clients listed there. But, those clients don't know which virtual server to connect to. Thanks for any tips and insights.
