Hi everyone.
Please consider following scenario:
VM----PG-A---vSW---vmnic1-------f1-Physical SW
|-----vmic2------f2
PG A has following NIC teaming policy:
vmnic1 active
vmnic2 standby.
Let say physical SW transmits a ARP for VM's IP on f2. What will VSW do next? Will it discard this ARP because it is received on standby vmnic2? Or will it transmit it to VM ?
Thanks and have a good day!!
With the mentioned settings (even with default failover&teaming), a VM's virtual network adapter will be mapped to a vmnic at power on, and will only send/receive traffic through that vmnic.

Thanks for your response!!
But I see different behavior:
Test set up:
ESXI 6.5
VMNIC2 is active, VMNIC 3 is stand by.
VMNIC2--------gig0/13 Physical SW
VMNIC3--------gig0/14
Physiacl sw set up:
int gig 0/14
switchport mode trunk
switch trunk encapsulation dot1q
switch trunk allowed vlan 24
int vlan 24
ip address 24.24.24.1/24
Ubuntu wire shark machine:
24.24.24.24.24
Ping issued to 24.24.24.24 from physical SW, is send out of gig 0/14, connected standby port VMNIC3.
Ubuntu does see arp packet from physical switch
So we do see traffic received on standby uplink is forwarded to attached VM. Is this expected behavior ?
Do you see mac address of vmnic3 in the capture
can u use esxtop and type n to see to which network card vm is mapped to
