DLSw support for SNA

Alejandro Rosales — Tue, 14 Jan 2003 14:14:21 GMT

How do I "support DLSw on a HP 9000 class D"?

I was recently asked this from IBM, because they are replacing hardware, and to increase reliability for SNA over our WAN.

As far as I know DLSw can be encapsulated inside tcp/ip, to avoid the LLC timeouts that slow SNA over a WAN, and is meant to replace SRB, but I don't quite understand how should my HP 9000 D class must "support it". Is this acomplished by installing new drivers? or a kernel parameter?

Can anyone shed a bit of light on this please?

I guess this is what they think you might have:

Normally your friendly router would take over the chore of stripping off the DLSw encapsulation and returning it to raw SNA. Apparently there are products which can eliminate the router.

I think it's a technology that HP picked up from Compaq since when you search for HP NonStop you get:

Don't see any indication that it has been ported to the 9000.
