1.3.6.1.2.1.34.8.1.2.1.4
This object allows entries to be created and deleted in the tn3270eSrvrPortTable. Entries may also be created and deleted as a result of implementation- dependent operations. Since this is the only accessible object in this table, a Management Station can create a conceptual row via a SET operation that specifies a value only for this object. An entry in this table is deleted by setting this object to destroy(6). Deletion of a tn3270eSrvrPortEntry has no effect on any other table entry defined by this MIB.
