Hello, I am trying to integrate USRP-X410 with XL710 intel PCIe NIC card through QSFP ports.
LED on both sides is off and I cannot ping USRP (192.168.10.2 and 192.168.20.2) through XL710. PCI card ports can be ping successfully, as IP addresses configured in the same subnetwork. Therefore, it seems link cannot establish between USRP-X410 and XL710 NIC. I think, it may because of rate mismatch between USRP-X410 and XL710 NIC card. (While USRP X410 with QSFP28 supports 10GE and 100GE, XL710 with QSFP+ only supports 40GE). Is there any way of auto-negotiating for speed in USRP, or other solution to help overcome this issue. Thank you. Here is my hardware setup. \- Ubuntu 22.04 \- USRP X410 \- UHD v4.4.0.0 \- GNU radio v3.10.5.1 \- Dual Port 40G QSFP+ NIC - Intel XL710 \- 40G QSFP+ DAC Cable - 40GBASE-CR4 Passive Direct Attach Copper Twinax QSFP Cable (from 10Gtek) BTW, I tried both X4_200 (10GE) and CG_400 (100GE) FPGA flavors, but still same problem.
