  1. Performing a read of the SA's ClassPortInfo attribute by issuing a SubnAdm Get(ClassPortInfo) GMP to the port specified by the issuing port's PortInfo.MasterSMLID attribute element. The GMP must have the following characteristics:

    - The SL used must be the one specified in the PortInfo.MasterSMSL attribute element.

    - The packet's SLID must be set to the base LID ...
