Issue

In a MetroCluster configuration, a data LIF may be replicated to a port with a different VLAN during switchover or switchback. This can cause client outages. ONTAP now checks for VLAN mismatches during the validation phase of switchover and switchback and displays a soft veto when a mismatch is detected. The check returns immediately during an unplanned switchover.
