The location of the contained service. The MIB defines the
following tables which may be pointed to by this column:
etsysFWServiceTable
Implementations should prevent recursion and return the
inconsistentName exception if the SnmpAdminString value
references an etsysFWServiceGroupTable row that already
contains the etsysFWServiceGroupName of this row.
If this column is set to a SnmpAdminString value which
references a non-existent row in an otherwise supported
table, the inconsistentName exception should be returned.
If the table or scalar pointed to by the SnmpAdminString is
not supported at all, then an inconsistentValue exception
should be returned.
