SA Accessed Using GMPs

Other entities access the SA database using GMPs (refer to Table 33-1 on this page) with the Management Class field set to SubnAdm, and using one of the SA methods (see Table 33-3 on page 925) to act upon one or more SA attributes (see Table 33-4 on page 927). Table 33-2 on page 920 provides a description of each of the MAD fields in an SA GMP.
