Herminia,

In order for us to get an idea of what is going on can you provide the following
data for the x25 connection:

show sna cp serv t g XXXX all

show qllc link XXXX station * all

show lapb link * all

show lapb  port * all

show x25 access all

sho modem conn line * all

sho modem conn data port * all


Send a copy of the NCL startup script for Peer Server and X25.

---------------------------------------------------------------------
1) Is this a direct attach line ?

>>      Now the main question: who has to initiate the x25 call? If we are
>>	a secondary station, shouldn't we send a kind of Init self?

To answer your question, if I understand it correctly, you will not see
anything for the LU establishment until after you have the x25 link up
and running.  In other words, you are not at that point yet.

	Hi,

	before writing ncl output and configs, let me clarify one point:

	X.25 link is over a public PSDN and its working fine. I know it
	because when configuring qllc link station as negotiated, a call
	is established.

	Hope that following info is useful. Thanks,
	Herminia.

Herminia,

It looks like the qllc link station is waiting for a call from the
IBM side, but the link is configured so that only peer server can
initiate the call.

CHANGE YOUR USAGE CONFIGURATION ON :
	Node 0 QLLC Link QLLC-1 Station STN-1
FROM :
	Usage Type                        = Outgoing
TO :
	Usage Type                        = both (or incoming)

    Jim, thnks for your fast reply.
    
    Fortunately we have an x25 connection with customer and can do testing
    immediately. Now I have followed your indications and problem is
    exactly the same after start and stop Peer Server. I'll include ncl
    output at the end of this reply.
    
    Customer says that another node (Stratus) connected also as Secondary,
    sends an x25 call to host once enabled. Should be the normal behaviour
    also for our Peer Server? 
    
    One more thing: host isn't an IBM, it's a Bull emulating SNA...

    I think it is all set. Why not ask the Bull side to initiate a call
    to the Peer Server. As secondary the Peer Server will not call the
    Bull side. If you look at your earlier traces you'll notice that
    as negotiable the Peer Server called the Bull and the Bull hung up.
    
    The Peer Server is waiting to be contacted.
    
    Bill

    Bill, thanks for your reply.
    
    This is the key question I asked for in .0 : we can see that Peer
    Server is waiting for contact, but what I wanted to know is if this 
    is the normal behaviour in SNA protocol. I need to be sure about it to
    discuss with customer and Bull's communication specialist.
    
    One more question: is there any good Digital or IBM or whatever manual
    where SNA is explained in detail?
    
    Regards,
    Herminia

    re -.1
    
    >>>I wanted to know is if this is the normal behaviour in SNA protocol.
    
    This is not SNA protocol, it is QLLC data link over X.25. A Network
    Protocols Handbook will be helpful here.
    
    >>> ... where SNA is explained in detail?
    
    IBM has many books on SNA. There is also a good SNA book from
    J. Ranaude Series (Hope I spelled correctly). Check the local
    technical bookstore. In Burlington Mass., it's Softpro.
    
    Bill

    Thanks for your answers.
    
    It seems now that Bull assumes the problem and customer will change
    back to SDLC.
    
    Regards,
    Herminia
