Connectivity issues when using nic teaming

$

Hello!

There're three host computers in my test lab - Host1, Host2 and Host3.

Host3 has three physical nics, two of them are used for Hyper-V - there's a virtual machine namedFW with the nic = 10.10.0.101 (connected to the production network) and nic2 =20.1.1.1 - this nic2 is a default gateway for the test network 20.1.1.0/24 (consisting of several virtual machines hosted on Host1/Host2/Host3).

Host1 has three physical nics, the two of them are members of the team (VM-TEAM):


Virtual machine DC (hosted on Host1) uses the VM-TEAM as its network adapter with the ip = 20.1.1.2

Vm FW and vm DC are connected to the same 5-port 1Gb switch:FW is connected by the single utp5 cable, DC - by the two cables.

The problem: when coping any data from DC to FW (or vice versa) copy process stops after several seconds, then after ~10-60 seconds proceeds, then stops again and etc...


This problem has never arisen when I was using a SINGLE nic for the Hyper-V, NOT teamed adapters.

Are there any settings/known issues for the nic teaming that could lead to such problem?

Thank you in advance,

Michael
