Jetson agx orin: pcie i210 network link lost

HI, We design the AGX ORIN carrier board , use the pcie switch PI7C9X2G1616PR to trans one 1x8 pcie channel to 8x1 pcie channels, and use 5x1 pcie channels translate to 5 ethernet through intel I210AT.
and we meet a problem. when the network running mable 1 day or several days ,the net link would ocassionally lost, we connect one net RJ45 of five. in different network but meet the same problem, the net link would lost afer several days working. but we use LSPCIE to check the hardware information , the ethernet pci device is OK.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Can this issue be reproduced with AGX Orin devkit?
Which JetPack SW is using?
