Each conceptual row represents a static NAT mapping.
Entries in this table can be created or deleted via SNMP operations.
A corresponding conceptual row in the tmnxNatVrtrTable must exist
while creating a row in this table.
For every conceptual row in this table, a row can be found in the
tmnxNatMapLsnHostTable; the value of the object
tmnxNatMapLsnHostAdminState in that row specifies the administrative
state of all corresponding rows in this table.
