Please use the below SQL query to unmonitor the physical ports for Juniper devices.
Update p Set IsMonitored=0 From UDT_Port p Innerjoin Nodes n on n.NodeID= P.NodeID
where n.Vendor like'Juniper Networks%'andcharindex('.',p.Name,1)=0
If Ports are rediscovered, then physical ports will be monitored. So please rerun the above SQL query to unmonitor the physical ports again.
