Why doesn't my VLAN IP Address work when I apply it to my Real-Time Target?Primary Software: LabVIEW Modules>>Real-Time ModulePrimary Software Version: 8.6.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I have a set of IP Addresses that are restricted into a VLAN. When I use one of the IP Address in that range as the IP Address of my Real-Time (RT) Target, I cannot ping or otherwise use the target. When I use another IP Address for this setting, everything works fine. Why is this? Solution: VLAN is currently (8.6.1) not supported by the Real-Time ethernet drivers that come with the RT Target. Troubleshooting steps to take in this case are to verify that the IP addresses were configured correctly (normally this is done by a company's in-house IT department) by assigning one of the addresses to a static computer and then try to ping it. If the ping returns ok, then the IP address is ok but it is restricted by the VLAN and the RT Target ethernet drivers are the issue. There is currently no known work around for this issue to be able to still use the VLAN IP addresses. The best course of action would be to use a less restricted IP address for the Network Settings of the RT Target. VLAN IP address ranges are normally used to have a secure section of IP addresses that other people on the network can't access (say if you wanted to assign these to a bank of targets and you don't want these targets available to other users on the network). An easier way than setting up a VLAN (and is also fully supported) is to set up a Subnet for the range of IP addresses you want. These IP addresses will only be available for the users that are on the same subnet so you can explictly select who can view the target IP addresses.
