A medium-size enterprise runs a vSphere 7.0 cluster with two hosts (HostA and HostB) for production VMs. Each host has two 10GbE uplinks (vmnic0 and vmnic1) connected to separate physical switches (SW1 and SW2) for redundancy. A single vSphere standard switch (vSwitch0) uses both uplinks with teaming policy set to 'Route based on originating virtual port ID,' 'Network failure detection: Link status only,' and 'Notify switches: Yes.' Lately, several VMs running on HostA experience intermittent network disconnections lasting 20–30 seconds, while VMs on HostB are unaffected. The administrator checks vCenter events and sees repeated messages: 'Lost uplink redundancy on vSwitch0. vmnic0 is down.' followed seconds later by 'Uplink redundancy restored. vmnic0 is up.' The physical switch SW1's log shows the port for vmnic0 transitions through spanning-tree listening and learning states each time this occurs, taking about 15 seconds. The link is a trunk allowing all necessary VLANs, with no errors or security violations. The network team has already swapped the fiber cable and SFP+ transceiver for vmnic0 without improvement. The VMs affected are those whose virtual ports are pinned to vmnic0 by the load-balancing policy; VMs pinned to vmnic1 never experience disconnections.
