snaNodeAdminTable OBJECT-TYPE
SYNTAX SEQUENCE OF SnaNodeAdminEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table contains objects which describe the
configuration parameters for an SNA Node. Link
specific configuration objects are contained in
a separate MIB module (e.g., SNA DLC MIB)
corresponding to the link type.
The table snaNodeAdminLinkTable contains objects
which identify the relationship between node instances
and link instances.
The entries (i.e., rows) in this table can be created
by either an Agent or a Management Station.
The Management Station can do this through setting
the appropriate value in the snaNodeAdminRowStatus.
The snaNodeAdminRowStatus object describes the
status of an entry and is used to change the status
of an entry. The entry is deleted by an Agent based
on the value of the snaNodeAdminRowStatus.
The snaNodeAdminState object describes the desired
operational state of a Node and is used to change the
operational state of a Node. For example, such
information may be obtained from a configuration file.
How an Agent or a Management Station obtains the
initial value of each object at creation time is an
implementation specific issue.
For each entry in this table, there is a corresponding
entry in the snaNodeOperTable.
While the objects in this table describe the desired
or configured operational values of the SNA Node, the
actual runtime values are contained in
snaNodeOperTable."

not listed in this enumeration,
startup (2) - at SNA services' initialization time
(this is the default),
demand (3) - only when LU is requested by application,
or
onlyMS (4) - by a Management Station only.
A write operation to this object may immediately
change the operational value reflected
in snaNodeOperEnablingMethod depending
on the Agent implementation. If the Agent
implementation accepts immediate changes, then the
behavior of the Node changes immediately and not only
after the next system startup of the SNA services.
An immediate change may only apply when the
current value 'demand (3)' is changed to 'onlyMS (4)'
and vice versa."

snaNodeAdminLuTermDefault OBJECT-TYPE
SYNTAX INTEGER {
unbind (1),
termself (2),

}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The value indicates the desired default method
used to deactivate LUs for this Node
For LU6.2s, 'unbind(1)' is the only valid value.
unbind(1) - terminate the LU-LU session by sending
an SNA UNBIND request.
termself(2) - terminate the LU-LU session by sending
an SNA TERM-SELF (Terminate Self) request on
the SSCP-LU session. The SSCP will inform the
remote session LU partner to send an UNBIND
request to terminate the session.
rshutd(3) - terminate the LU-LU session by sending
an SNA RSHUTD (Request ShutDown) request to
the remote session LU partner. The remote LU
will then send an UNBIND request to terminate
the session.
poweroff(4) - terminate the LU-LU session by sending
either an SNA LUSTAT (LU Status) request on
the LU-LU session or an SNA NOTIFY request on
the SSCP-LU session indicating that the LU has
been powered off. Sending both is also
acceptable. The result should be that the
remote session LU partner will send an UNBIND
to terminate the session.
The default behavior indicated by the value of this
object may be overridden for an LU instance. The
override is performed by setting the snaLuAdminTerm
object instance in the snaLuAdminTable to the desired
value.
A write operation to this object may immediately
change the operational value reflected
in snaNodeOperLuTermDefault depending
on the Agent implementation."
::= { snaNodeAdminEntry 8 }
snaNodeAdminMaxLu OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The maximum number of LUs that may be
activated for this Node. For PU2.1, this object
refers to the number of dependent LUs.
A write operation to this object will
not change the operational value reflected

DESCRIPTION
"The value identifies the remote host associated
with this Node.
Since SSCP Id's may not be unique
across hosts, the host description
is required to uniquely identify the SSCP.
This object is only applicable to PU2.0 type
Nodes. If the remote host is unknown, then the
value is the null string.
A write operation to this object may immediately
change the operational value reflected
in snaNodeOperHostDescription depending
on the Agent implementation."

DESCRIPTION
"The value indicates the desired method to be used
by the Agent to stop a Node (i.e., change the Node's
operational state to inactive(1) ).
The values have the following meaning:
other (1) - used for proprietary
methods not listed in this enumeration.
normal(2) - deactivate only when there is no more
activity on this Node (i.e., all data flows
have been completed and all sessions
have been terminated).
immed(3) - deactivate immediately regardless of
current activities on this Node. Wait for
deactivation responses (from remote Node)
before changing the Node state to inactive.
force(4) - deactivate immediately regardless of
current activities on this Node. Do not wait
for deactivation responses (from remote Node)
before changing the Node state to inactive.

::= { snaNodeAdminEntry 11 }
snaNodeAdminState OBJECT-TYPE
SYNTAX INTEGER {
inactive (1),
active (2)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The value indicates the desired operational
state of the SNA Node. This object is used
by the Management Station to
activate or deactivate the Node.
If the current value in snaNodeOperState is
'active (2)', then setting this object to
'inactive (1)' will initiate the Node shutdown
process using the method indicated
by snaNodeOperStopMethod.
If the current value in snaNodeOperState is
'inactive (1)', then setting this object to
'active (2)' will initiate the
Node's activation.
A Management Station can always set this object to
'active (2)' irrespective of the value in the
snaOperEnablingMethod."
::= { snaNodeAdminEntry 12 }
snaNodeAdminRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object is used by a Management Station to
create or delete the row entry in the
snaNodeAdminTable following
the RowStatus textual convention.
Upon successful creation of
the row, an Agent automatically creates a
corresponding entry in the snaNodeOperTable with
snaNodeOperState equal to 'inactive (1)'.
Row deletion can be Management Station or Agent
initiated:
(a) The Management Station can set the value to
'destroy (6)' only when the value of
snaNodeOperState of this Node instance is
'inactive (1)'. The Agent will then delete the rows
corresponding to this Node instance from the
snaNodeAdminTable and the snaNodeOperTable.
(b) The Agent detects that a row is in the
'notReady (3)' state for greater than a
default period of 5 minutes.
(c) All rows with the snaNodeAdminRowStatus object's
value of 'notReady (3)' will be removed upon the
next initialization of the SNA services."

"The value indicates the timestamp
(e.g., the Agent's sysUpTime value) of the last
change made to any object in the snaNodeAdminTable,
including row deletions/additions (e.g., changes to
snaNodeAdminRowStatus values).
This object can be used to reduce frequent
retrievals of the snaNodeAdminTable by a Management
Station. It is expected that a Management Station
will periodically poll this object and compare its
current value with the previous one. A difference
indicates that some Node configuration information
has been changed. Only then will the Management

snaNodeLinkAdminTable OBJECT-TYPE
SYNTAX SEQUENCE OF SnaNodeLinkAdminEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table contains the references to link
specific tables. If a Node is configured for
multiple links, then the Node will have
multiple entries in this table.
The entries in this table can be generated
initially, after initialization of SNA service,
by the Agent which uses information from
Node configuration file.
Subsequent modifications of parameters,
creation of new Nodes link entries and deletion
of entries is possible.
The modification to this table can be
saved in the Node configuration file for the
next initialization of SNA service, but the mechanism
for this function is not defined here."
::= { snaNode 6 }
snaNodeLinkAdminEntry OBJECT-TYPE
SYNTAX SnaNodeLinkAdminEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Entry contains the configuration information that
associates a Node instance to one link instance.
The objects in the entry have read-create access.
Entry can be created, modified or deleted.
The object snaNodeLinkAdminRowStatus is used (set)
to create or delete an entry.
The object snaNodeLinkAdminSpecific can be set
later, after the entry has been created."

RowStatus
}
snaNodeLinkAdminIndex OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This value is used to index the instances of objects.
If an Agent creates the entry, then it will assign
this number otherwise a Management Station
generates a random number when it reserves the
entry for creation."
::= { snaNodeLinkAdminEntry 1 }
snaNodeLinkAdminSpecific OBJECT-TYPE
SYNTAX InstancePointer
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This value points to the row in the table
containing information on the link instance.
(e.g., the sdlcLSAdminTable of
the SNA DLC MIB module)."
::= { snaNodeLinkAdminEntry 2 }
snaNodeLinkAdminMaxPiu OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This value identifies the maximum number of octets
that can be exchanged by this Node in one
Path Information Unit (PIU)."
::= { snaNodeLinkAdminEntry 3 }
snaNodeLinkAdminRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object is used by a Management Station to
create or delete the row entry in the
snaNodeLinkAdminTable.
To activate a row, a Management Station sets the value
to 'active (1)' or 'notReady (3)'. Upon successful
creation of the row, the Agent automatically creates
a corresponding entry in the snaNodeLinkOperTable.
Row deletion can be Management Station or Agent
initiated:
(a) The Management Station can set the value to
'destroy (6)' only when the value of
snaNodeLinkOperState of this Link
instance is 'inactive (1)'. The Agent will then
delete the row corresponding to this Link
instance from snaNodeLinkOperTable and
from snaNodeLinkAdminTable.
(b) The Agent detects that a row is in the
'notReady (3)' state for greater than a
default period of 5 minutes.
(c) The Agent will not include a row with RowStatus=
'notReady (3)', after SNA system re-initialization
(e.g., reboot)."

snaNodeLinkAdminTableLastChange OBJECT-TYPE
SYNTAX TimeStamp
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The timestamp (e.g., the Agent's sysUpTime value)
at the last
change made to any object in the snaNodeLinkAdminTable,
including row deletions/additions (i.e., changes
to the snaNodeLinkAdminRowStatus object).
This object can be used to reduce frequent
retrievals of the snaNodeLinkAdminTable by a
Management Station. It is expected that a
Management Station will periodically poll this
object and compare its current value with the
previous one.
A difference indicates that some Node operational
information has been changed. Only then will the
Management Station retrieve the entire table."
