SDLC PU 2.0 and SNAsw

[edaguet]

Hi all,

I would like to connect a 3174 controller on my roouter as follows:

3174---[SDLC on serial]---RTR---[SNAsw using HPR/IP]---OSA on MVS.

i have 3 questions:

1/ the 3174 use LLC2. So do i use sdllc command instead of sdlc command ?

2/ do i implement sdlc/sdllc xid C1 <IDBLK_IDNUM>?

2/ my MVS engineer said me that EE do not understand that SNA over LLC2 using SNAsw from router?

If it is possible, what is the VTAM configuration...

Thanks for answers

I think you can configure this with vdlc. See the following link "SNASw Using Local Switching with SDLC Configuration Example ":

http://cio.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fibm_c/bcfpart2/bcfsnasw.htm#wp1003110

It should not matter that the host connection is EE.

I hope this helps.

Regards,

Bob

The SNAsw router wait DACTPU command to desactivate the 3174 sessions. How can i parameters the DACTPU timeout on the SNAsw router to reset the 3174 status on SDLC links ?

Hi Silvere,

How are you simulating the VTAM crash? It looks like VTAM may still be sending out a DACTPU, which we send downstream, and need a response to. I don't know that SNASw would send out a DACTPU on its own on a pipe failure. Do you have a DLC trace? What is the status of the PU on the host? Do you know any reason why the 3174 is not responding to the DACTPU?

Is there a Service Request open for this? This sounds very much like SR 601565131. In that case we suggested removing ANS=CONT from the PU definition. How is this PU defined?

There is no timeout option for DACTPU rsp. SNASw either needs a response from downstream, or somehow change the behaviour of the flow sequence.

Regards,

Bob
