The issue can occur due to Spanning Tree Protocol (STP) loops in the network that cause packet drops from the specific host. In addition to packet drops, STP loops lead to several other symptoms, which are listed here:
Loss of connectivity to, from, and through affected network regions.
High link utilization (often 100 percent).
High switch backplane utilization (compared to the baseline utilization).
Syslog messages that indicate packet looping in the network (for example, HSRP duplicate IP address messages).
Syslog messages that indicate constant address relearning or MAC address flapping messages.
An increase in the number of output drops on many interfaces.

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
