Hi. We recently configured LACP with 4 interfaces in our dual controller FAS2240-4. We are running ONTAP 8.1.1. Recently we have started facing an issue where the vif interface is losing network connectivity but gets restored after a few minutes. We use PRTG to monitor our networks and it shows the vif interface as down during this period. The FAS is connected to Avaya ERS 5500 switches and are configured with LACP. Is there a configuration issue?
