OSI Layer Management
Each of the OSI layers has a layer management entity (LME) that:
is responsible for specific layer management information
can pass that management information to the Network Management
Agent (NMA) via each layer’s attributes (see Appendix D for details on
layer attributes).
You can view only the following type of attributes:
attributes that can be retrieved and set
the events (if any) that can be detected by a LME
the actions (if any) that can take place within a layer
In the following tables:
all listed attributes are readable (you can retrieve with a GET operation)
we abbreviate ‘‘attribute I.D.” as Attrid
a ‘‘yes” in the settable column indicate you can write to that attribute,
and a dash (
____)
in that column indicates you cannot write to it
if you can write to an attribute, the Set value or range column indicates
the range of values to which you can set that attribute
For more information on specific Layer Management Attributes, refer to
the MAP 3.0 specifications.
The following table lists the ACSE attributes.
