SNASWITCHING call-out

[msartorel]

SNASWITCHING is able to call-out a remote SNA PU if it receives an order from VTAM Host. VTAM host uses DLCADDR parameters to send orders to SNASW. I am not able to find how to code the DLCADDR parameters in the way SNASW understand them.

From reading the SNASw source code I see that we require a dlc type "TR", but I think it may work for X.25 via VDLC as long as you code TR. If anyone has found otherwise please post it.

You would need to code in the name of the port configured with the "snasw port" config command, that SNASw will use for the downstream dial out connection. You will also need to code the virtual mac address. This information is all to tell SNASw which port to establish the link over, and which address to connect out to. The media translation should convert this virtual mac address to the x.25 address as per the rest of your router configuration.

So Bob,

let me summarize to see if I understood this correctly. I should code:

PATH DLURNAME=

DLCADDR=(1,C,TR),

DLCADDR=(2,C,VDLC0001), (8 characters to avoid the

DLCADDR=(3,X,04),

DLCADDR=(4,X,4000.0000.0002 )

(the above were taken from the first answer to this post).

What do you think? (sorry for insisting so much on this "how to" but I could not find any documentation that covers this end to end, not even in ibm).

[rclousto]

Yes, that is correct except that IBM does not use the dotted format that Cisco uses for mac addrs. Code it as

DLCADDR=(4,X,400000000002)

I am going to try to find a good place to document this in the IOS guides. Because there are some SNASw specific requirements for the fields we should probably cover this in our documentation. Thanks for raising this point.

Regards,

Bob
