I have a vSwitch VS1 with two port groups PG1 and PG2:
VS1: Promiscuous mode:Reject
PG2: Promiscuous mode:Accept
Both PG1 and PG2 are configured as same VLAN.
I put a Linux VM under PG2, configured as Promiscuous enabled, then I found when I run tcpdump, it capthced traffics for VMs on both PG1 and PG2 group.
I thought it should only capture the traffic on PG2 group? Anybody can confirm if this also happen on your ESX environment?
My ESX server is 4.0 U2.
