how to config class

[Julie Xu]

Hi, 

have tested put class vlan418RIS class below MicrsoftRIS not work.
have tested put the class vlan418RIS in subnet and not work also.

is possible I can modify the class MicrosoftRIS to achive:
    if vendor-class-identifier "PXEClient"
         then
              if relay agent ip address 10.2.2.1
               then
                   server-identifier 10.2.2.10
               else
                   server-identifier 10.1.1.10
                fi
           fi

please advice
