Why is my throughput intermittently slow on a dual NIC Linux system?

A. If your Linux MIMIC system has multiple active network interfaces connected to the same LAN, and you are experiencing drops in PDU throughput while polling MIMIC agents, it may be due to one network interface running slower than the other. Linux will route traffic through the NIC according to the arp tables regardless of the interface an agent IP address is assigned to.
