Multiple NICs, same subnet

[philbilly]

I am building a test device requiring 6 IP addresses on the same subnet, unique 4th octets (xxx.xxx.xxx.101,102,103,...).  I am using 6 pxi 8231 NICs., 8108 controller, and 1045 PXI chaasis.  MAX will allow the target to configure 3 channels with an odd 4th octet, using 255.255.255.254.  The even IP addresses are disabled with the message one device per subnet.  The mask 255.255.255.255 is defined as an invalid mask by MAX.  Are there any suggestions to resolve this?  Can it be done using a hub or switch and a single card  (NIC)by tricking up the mask (255.255.255.0)?  I have also attempted this programmatically but could not confirm the IP addresses that have been set on the NICS

Thanks,

Phil.

Hi Phil,

Is there a reason why you have chosen 255.255.255.254 as a subnet? I would suggest using a lower value for the 4th octet.

The use of the 255.255.255.254 was recommended by the NI engineer who is attempting to help me resolve this problem.  I have attempted to use several masks without success.  I understand the mask is currently inhibiting my ability to load the even ip addresses.
