Failed to connect instrument to NI-MAX

[Heyi]

Hi, 

I am trying to connect my FieldFox N9926A from Agilent Technolies to NI-MAX. I directly connect the FiledFox to my laptop using an ethernet cable. I have already detected it on my laptop using Keysight Connection Expert (shown in the second figure). The issue is that when I tried to add it to NI-MAX: "Network Devices" - "Add network devices" - "VISA TCP/IP resource", it is shown that "No VXI-11 LAN/LXI instruments were found on the pocal subnet".

Thanks a lot!
