    standby adapter

    sadom Novice

      esxi 6.5 u2 vSwitch configured as 1 active uplink and 1 standby uplink. I didnt understand why the standby adapter in which scenarios. I wonder why and in what scenarios it is used

          All traffic is currently passing between your vSwitch and your physical network through vmnic0 (as it is active).

           

          Should anything fail causing that NIC port in your server to lose link status, all traffic would pass through vmnic1 instead (as it is the standby).

           

          Rather than having both adapters as active, you have a hot standby - meaning that performance in the event of a failover will be predictable (assuming vmnic0 and vmnic1 can offer the same throughput).

            You have asked a related question before, I recommend taking a look back at the replies in that thread as well as the links in those replies.

                I answered that above:
