To enable a Q in Q untagged SAP on an NE

Note: The Enable Q in Q Untagged Sap parameter is not supported on the 7950 XRS as it is enabled by default.

Steps
 

On the equipment tree, right-click on an NE and choose Properties. The Network Element (Edit) form opens.


Click on the Globals tab, then on the Ethernet tab.


Enable the Enable Q in Q Untagged Sap parameter.

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.


Save your changes and close the form.
