                         APPN REFERENCE SIG
                    AIW 10 - San Jose, California
_______________________________________________________________________

The SIG was chaired by Gary Schultz (IBM) in the absence of the regular
Chair, Ralph Case, who was unable to attend for family (enlargement)
reasons.

Gary and Bob Moore (IBM) announced the planned availability of SNA
Formats as two books, probably in June from Mechanicsburg.  Essentially,
the plan is to split off the Network Management formats into their own
book.  We'll be notifying the AIW of specific ordering information
when the books are known to Mechanicsburg.

After reviewing changes reaching approval status since AIW-9,
the meeting proceeded with the current items.

Gary Schultz pointed out a minor fix to the SNA Formats book
to bring it in line with correct information in the APPN Architecture
Reference regarding sense data values 0809 0045/6.

Bob Moore reported on MIB SIG work affecting the Architecture Reference.

Gary Schultz filled in for the absent Ed Tremblay by presenting and
leading the discussion on Ed's DLUR items.  Approval was agreed upon
for the items clarifying sense data used for "surprise" CP-SVR pipe
activations and changing formats for APPN frame relay and V.25 bis
signaling information.  Assignment of option set number 1116 was
clarified (it was inadvertently used for two option sets); the DLUR
usage will prevail, while the other option set will be known as 1117.
Two other items related to DLUR strategy for DLUS searches and redriving
SSCP-PU activation after receiving DACTPU will be combined into a
single item and reported on again.  The proposal on DLUR handling of
Locates with OCR=1 while the LU or DLUR-DLUS connection is inactive
will be resubmitted to accommodate minor comments.

Bob Moore discussed the use of information in CV40 for network
management purposes.

Roy Brabson (IBM) led a discussion of how TRS compares characteristics
in received and stored TDUs.  The SIG consensus was that the APPN
Architecture Reference should clarify this point explicitly along
the lines described by Roy.

A fruitful discussion ensued on how to get VTAM PU and LU names to
type 2.0 nodes, or to nodes representing them.  Two proposals, one
from Dave Bryant (3Com) and one from Jim Cobban (Nortel) were
discussed.  Jim Fletcher (IBM, VTAM) led the way to a synthesis
of the proposals that the interested parties found acceptable.
Details will be generated for AIW perusal and approval (if
any architecture hits result) for the next meeting.

Two items were added at the meeting to the agenda, both at the
request of Cisco representatives.  Dave McCowan presented a proposal
for an extension allowing vendor-specific control vectors on the
CP Capabilities GDS variable.  This resulted in a spirited debate
over the goals themselves rather than the formats, and no consensus
was reached.  To preserve the AIW's customary collegiality, the
group heeded Jim Fletcher's advice to pursue the point further
using this electronic channel.  Dario Calia presented a proposal
for a DLUR extension that was generally well received.  He is planning
to publish his refined proposal electronically on this channel.

The meeting adjourned amicably with a sense of having accomplished
useful work and exchange of information.
