Hi,
W have Cisco Nexus N3K-C3548P-10GX switches in the data center access. All ESXi hosts in VxRail infrastructure are generating this alarm on the vCenter:
high pNIC error rate being detected
Switch interfaces are all similar. There are output drops but other than that nothing significant. I am wondering what could be the reason.
