Here are my queries -
1.Could the tunneling protocols...DLSw, STUN , BSTUN
be used to tunnel just any protocol, or is it specific to IBM SNA , NetBIOS?
we are interested in connecting NCR mainframe systems over IP.These NCR systems talk NCR proprietary protocol, and connect by a Serial Async interface.
2. Assuming that the tunneling protocol can tunnel
even the NCR proprietary protocol (like it does SNA),
should only STUN / BSTUN be used since a serial
interface is involved...and not DLSw which would run
only with Ethernet / token ring in the LAN ?
If someone has worked on this..or has any idea on how
things work...please do let me know.
Thanks in advance,
Shilpa.

Hi,
the question is what exactly is the protocol you are talking about?
We do have some support for async generic in bstun.
Stun basic transports virtualy everything but it needs a synchron protocol, basicaly 7E's to identify the start of frame and end of frame. It does not deal with async protocols.
Dlsw does only do sdlc and qllc on the serial
connected interfaces.
I would advice to open a case with cisco tac, the ibm team, please mention you want to use bstun to tunnel a async protocol, and then determine what exact protocol you are dealing with. Based on the outcome of this we can determine futher if there is support for this protocol or not.

Thanks for that.
I needed to know if DLSw was tunneling protocol specific to IBM SNA. Looks like it is.
So now, like you said I would need to find out the protocol which NCR Mainframe (which need to be connected in my set up) talk.
Thanks again.
Shilpa.
