When you enable the Enable Q in Q Untagged Sap parameter, the NFM-P allows the creation of the following two default SAP types:
The SAP type *.null functions as a default SAP for single-tagged frames on a Q in Q port. This SAP accepts single tags in the range 0 to 4095 as well as untagged traffic.
The SAP type *.* functions as a default SAP for double-tagged frames in a Q on Q port. This SAP accepts untagged, single-tagged, and double-tagged frames with tags in the range 0 to 4095.
