hi guys

I have a Blade chassis with 3 PowerEdge M910, this chassis has 8 Physical NICs connnected and each ESX 4.1 sees 10 vmnics, according to my networking guy these 8 NICs are using Etherchannels and all these Etherchannel have access to al VLANs in my case VLANs 40 - 50 - 700 - 800.

OK, I have 4 vmnics, vmnic6 to vmnic9, even when my Net guys says and show me that all the physical NICs have access to all VLANs, vmnic6 and vmnic8 have no access to VLAN_50 and this causes me that when vmotion VMs some VMs suddenly loss network connectivity.... on the other hand vmnic 7 and vmnic 9 listen in all VLANs.

someone else deployed this environment  but I had to do some migration to version 5 and I found out this issue..... so my question is since physical NICs are listining in all VLANs is there something I have to check at Dell level?

thanks a lot
