This happens when you enable iSCSI session monitoring after the iSCSI session starts. The information learned about iSCSI sessions on VLT LAGs synchronizes with the VLT peers. iSCSI session synchronization happens based on various scenarios: • If the iSCSI login request is received on an interface that belongs to a VLT LAG, the information synchronizes with VLT peer and the connection associates with the interface. • Any updates to connections, including aging updates that are learned on VLT LAG members synchronizes with the VLT peer. • If the iSCSI login request is received on a non-VLT interface, followed by a response from a VLT interface, the connection is associated with the VLT LAG interface and the information about the session synchronizes with the VLT peer.
