Hello all,
As per my understanding enabling fail-over will create the secondary virtual path, which gives me the failover of vNIC automatically with the secondary virtual path that got created & the traffic will be routed towards another FI.
While creating the vNIC templates & in most of the deployments i have seen.
No one is considering the enable failover checkbox & I would like to know the pro's & corn's.
In which situation do i need consider it ? What is the recommended practice?
Looking forward for the suggestions.
Regards,

Hi Gopi
This failover flag made a lot of sense in the past, e.g. when Window server only supported one vnic.
For VMware ESXi whether its vswitch, DVS, N1000v, it is recommended to not use this hardware failover flag, and let the OS switch handle it.
see eg
