i think i found it, but its kinda misleading the way it is named by Interface Type and this may be because of some RFC. i guess i'll live with it unless someone at Solarwinds speaks out about this. it involves switch modules with port names GigabitEthernet and/or Port.
Solarwinds calls a GigabitEthernet switch-port as ethernetCsmacd and a Port switch-port as gigabitEthernet.
Here's a basic report to catch this and i'm using a NODE Custom Property named Device.Type.
Interfaces.Caption AS Interface_Caption, Interfaces.FullName AS Full_Name, Interfaces.InterfaceTypeName AS Interface_Type_Name, Interfaces.InterfaceSpeed AS Interface_Speed, Interfaces.InterfaceTypeDescription AS Interface_Type_Description
Nodes INNER JOIN Interfaces ON (Nodes.NodeID = Interfaces.NodeID)
(Nodes.Device_Type = 'switch') AND
(Interfaces.InterfaceTypeName LIKE '%gigabitethernet%') OR
(Interfaces.Caption LIKE '%gigabitethernet%'))
ORDER BY 1 ASC
