RE: SNA over TCP/IP

["Carl Galgano" <cgalgano2@xxxxxxxxxxxxxxxxx>]

Keep in mind, that what I am suggesting is SNA (or SNADS) over ethernet, not
over IP.  The later suggests that you are encapsulating the SNA data within
IP packets (which is what Anynet does).  You can do SNA over ethernet if
there are no routers between your 2 AS400s.  Are they on the same LAN?  The
LAN does not care if you mix SNA and IP traffic over it (and IPX for that
matter).  The key here is that both boxes are on the same LAN.

Carl,

If I understood your comment correctly, SNADS can be setted up and used
without any changes in the TCP/IP line configuration. I didn't know that!
This is a great reason for a further use of SNADS. In our case it's more a
philosophic question than an actual question of transfer speed. Our customer
refuses the configuration of "old SNA stuff"
and SNADS unfortunately sounds like this.    
Thanks also to all the others for their response. DDM is obviously the
mostly used method. Regards, Werner Noll -----Ursprüngliche Nachricht-----

Werner:
You do not need to configure anynet to use SNADS over Ethernet.  If your
AS400s are on the same LAN, then you just configure the APPC controller
(type *LAN).  SNA over Ethernet requires you use the MAC address of the
Ethernet card.  That is how the addressing is done.  

If it is over a WAN and you are using CISCO routers, you can use dlsw to
route the SNA over the IP network.  Again, ANYNET is not required.

Hi All,

I'll have a discussion with a customer about the best methods of data
transfer between two iSeries systems. The systems are already connected by
TCP/IP. The issue is to transfer periodically files from one system to the
other. In the past we already used SNADS functions as well as FTP. I
personally prefer SNADS, which would require the Anynet-Support. In previous
postings I read something about a slow down when Anynet is used (in
comparison with pure SNA or pure TCP/IP). Would this be remarkable? Does
Anynet realy slow down also the interactive traffic on a TCP/IP line? Many
thanks for any arguments pros and cons.
