This is the MIB module for objects used to manage
network devices with DLUR capabilities.  This MIB
contains information that is useful for managing an APPN
product that implements a DLUR (Dependent Logical Unit



Requester).  The DLUR product has a client/server
relationship with an APPN product that implements a DLUS
(Dependent Logical Unit Server).    

Administratively assigned network name for the APPN node where
this DLUR implementation resides.  If this object has the same
value as the appnNodeCpName object in the APPN MIB, then the
two objects are referring to the same APPN node.    

The DLUR release level of this implementation.  This is the
value that is encoded in the DLUR/DLUS Capabilites (CV 51).
To insure consistent display, this one-byte value is encoded
here as two displayable characters that are equivalent to a
hexadecimal display.  For example, if the one-byte value as

encoded in CV51 is X'01', this object will contain the
displayable string '01'.    

Possible values are:


continueOrStop, stopOnly
                

Automatic Network Shutdown (ANS) capability of this node.

-  'continueOrStop' indicates that the DLUR implementation
supports either ANS value (continue or stop) as
specified by the DLUS on ACTPU for each PU.

-  'stopOnly' indicates that the DLUR implementation only
supports the ANS value of stop.

ANS = continue means that the DLUR node will keep LU-LU
sessions active even if SSCP-PU and SSCP-LU control sessions
are interrupted.

ANS = stop means that LU-LU sessions will be interrupted when
the SSCP-PU and SSCP-LU sessions are interrupted.    

Indication of whether this DLUR implementation can support
CPSVRMGR sessions that cross NetId boundaries.    

The SNA name of the defined default primary DLUS for all of
the PUs served by this DLUR.  This can be overridden for a

particular PU by a defined primary DLUS for that PU,
represented by the dlurPuDefPrimDlusName object.    

Indication of whether this DLUR implementation supports
forwarding of Network Name control vectors on ACTPUs and
ACTLUs to DLUR-served PUs and their associated LUs.

This object corresponds to byte 9. bit 3 of cv51.    

Indication of whether this DLUR implementation supports
nondisruptive deactivation of its DLUR-DLUS sessions.
Upon receiving from a DLUS an UNBIND for the CPSVRMGR pipe
with sense data X'08A0 000B', a DLUR that supports this
option immediately begins attempting to activate a CPSVRMGR
pipe with a DLUS other than the one that sent the UNBIND.

This object corresponds to byte 9. bit 4 of cv51.    

This table contains an ordered list of defined backup DLUSs
for all of the PUs served by this DLUR.  These can be
overridden for a particular PU by a list of defined backup
DLUSs for that PU, represented by the
dlurPuDefBackupDlusNameTable.  Entries in this table are

ordered from most preferred default backup DLUS to least
preferred.    

This table is indexed by an integer-valued index, which
orders the entries from most preferred default backup DLUS
to least preferred.    

Index for this table.  The index values start at 1,
which identifies the most preferred default backup DLUS.    

Fully qualified name of a default backup DLUS for PUs served
by this DLUR.    

Information about the PUs supported by this DLUR.    

Entry in a table of PU information, indexed by PU name.    

The SNA name of the PU.  This value is supplied to a PU by the
SSCP that activated it.  If a value has not been supplied, a
zero-length string is returned.    

Possible values are:


reset, pendReqActpuRsp, pendActpu, 
pendActpuRsp, active, pendLinkact, 
pendDactpuRsp, pendInop, pendInopActpu

Status of the DLUR-supported PU.  The following values are
defined:

reset(1)           -  reset
pendReqActpuRsp(2) -  pending a response from the DLUS
to a Request ACTPU
pendActpu(3)       -  pending an ACTPU from the DLUS
pendActpuRsp(4)    -  pending an ACTPU response from the PU
active(5)          -  active
pendLinkact(6)     -  pending activation of the link to a
downstream PU
pendDactpuRsp(7)   -  pending a DACTPU response from the PU
pendInop(8)        -  the CPSVRMGR pipe became inoperative
while the DLUR was pending an ACTPU
response from the PU
pendInopActpu(9)   -  when the DLUR was in the pendInop
state, a CPSVRMGR pipe became active
and a new ACTPU was received over it,
before a response to the previous
ACTPU was received from the PU.    

Possible values are:


continue, stop
                

The Automatic Network Shutdown (ANS) support configured for
this PU.  This value (as configured by the network
administrator) is sent by DLUS with ACTPU for each PU.

-  'continue' means that the DLUR node will attempt to keep
LU-LU sessions active even if SSCP-PU and SSCP-LU
control sessions are interrupted.

-  'stop' means that LU-LU sessions will be interrupted
when the SSCP-PU and SSCP-LU sessions are interrupted.    

Possible values are:


internal, downstream
                

Location of the DLUR-support PU:
internal(1)   - internal to the APPN node itself (no link)
downstream(2) - downstream of the APPN node (connected via
a link).    

Administratively assigned name of the link station through
which a downstream PU is connected to this DLUR.  A zero-length
string is returned for internal PUs.  If this object has the
same value as the appnLsName object in the APPN MIB, then the
two are identifying the same link station.    

Possible values are:


reset, pendingActive, active, 
pendingInactive
                

Status of the control session to the DLUS identified in
dlurPuActiveDlusName.  This is a combination of the separate
states for the contention-winner and contention-loser sessions:

reset(1)           - none of the cases below
pendingActive(2)   - either contention-winner session or
contention-loser session is pending active
active(3)          - contention-winner and contention-loser
sessions are both active
pendingInactive(4) - either contention-winner session or
contention-loser session is pending
inactive - this test is made AFTER the
'pendingActive' test.

The following matrix provides a different representation of
how the values of this object are related to the individual
states of the contention-winner and contention-loser sessions:

Conwinner

C ++++++++++++++++++++++++++++++++++
o pA | 2  |  2 | 2 | 2

r X  | 2  |  4 | 1 | 1
++++++++++++++++++++++++++++++++++

The SNA name of the active DLUS for this PU.  If its length
is not zero, this name follows the SnaControlPointName textual

convention.  A zero-length string indicates that the PU does
not currently have an active DLUS.    

The SNA name of the defined primary DLUS for this PU, if one
has been defined.  If present, this name follows the
SnaControlPointName textual convention.  A zero-length string
indicates that no primary DLUS has been defined for this PU, in
which case the global default represented by the
dlurDefaultDefPrimDlusName object is used.    

This table contains an ordered list of defined backup DLUSs
for those PUs served by this DLUR that have their own defined
backup DLUSs.  PUs that have no entries in this table use the
global default backup DLUSs for the DLUR, represented by the
dlurDefaultDefBackupDlusNameTable.  Entries in this table are
ordered from most preferred backup DLUS to least preferred for
each PU.    

This table is indexed by PU name and by an integer-valued
index, which orders the entries from most preferred backup DLUS
for the PU to least preferred.    

Locally administered name of the PU.  If this object has the
same value as the dlurPuName object, then the two are
identifying the same PU.    

Secondary index for this table.  The index values start at 1,
which identifies the most preferred backup DLUS for the PU.    

Fully qualified name of a backup DLUS for this PU.    

This entry is indexed by the name of the DLUS.    

The SNA name of a DLUS with which this DLUR currently has a
CPSVRMGR pipe established.    

Possible values are:


reset, pendingActive, active, 
pendingInactive
                

Status of the CPSVRMGR pipe between the DLUR and this DLUS.
This is a combination of the separate states for the
contention-winner and contention-loser sessions:

reset(1)           - none of the cases below
pendingActive(2)   - either contention-winner session or
contention-loser session is pending active
active(3)          - contention-winner and contention-loser
sessions are both active
pendingInactive(4) - either contention-winner session or
contention-loser session is pending
inactive - this test is made AFTER the
'pendingActive' test.
