Titolo: AS/400 & Ethernet >> 2501 routers >> IBM 5494 controller & Ethernet: Newby needs help

We have an AS/400 E series running V4R2 and an Ethernet TCP/IP network at
the host location in Texas. The remote location in Indiana has an IBM 5494
remote controller (with Twinax & Ethernet cards) and an Ethernet TCP/IP
network.
AS/400 & Ethernet > 2501 > CSU > DDS > CSU > 2501 > IBM 5494 & Ethernet
Currently the AS/400 is connected via Black Box CSU/DSUs on a 56KB DDS line
to the 5494 remote controller. There is no TCP/IP connection between the
Ethernet networks.
AS/400 > CSU > DDS > CSU > IBM 5494 > Ethernet
The object is to use the Cisco 2501 routers we have to route TCP/IP traffic
and AS/400 traffic over the existing CSU/DSUs and DDS line. Eventually we
will add another DDS line so I do not want to use my spare serial port. The
TCP/IP portion is done and works great in our test environment.
How do I get the AS/400 to communicate with the 5494 remote controller? Not
having a spare to test with really presents a problem. I understand that the
5494 can be configured to use the Ethernet card to communicate with the
AS/400. It is unclear in the 5494 documentation whether it can use TCP/IP or
if I have to use SNA. From the third party books I have the closest example
for SNA says to use source route bridging (which it says is only good for
Token Ring) and encapsulated SDLC (which SDLC commands only work with S0 or
S1 which I will be using for the WAN connection).
I appreciate any help anyone can provide.
Charles

It is my understanding that 5494 controllers ONLY run SNA.  You will have to
bridge the traffic with the routers....
Please email me directly with specifics

I'm not certain about the IBM 5494, but I'm pretty sure it is incapable
of running TCP/IP connect to the 400.
However, I am certain that the Perle 494 can use the enet card for
uplink to the 400 via TCP/IP.
You end up with:

     up?
YES, but there are 8 or 9 of them including E0. Should there be 8 or 9 of
them? Is it by chance showing all mac addresses running SNA on the network?

The 5494 does have an 10BaseT interface card, but really doesn't like
receiving extra data generated by other protocols (Appletalk, IPX, etc.).
We've been battling with 4 5494 controllers that, when they fail, do so at
the same time.  We've replaced 1 with a Perle 494.  Two of the remaining
seem to not want to vary on with the AS/400.  And of course, IBM blames the
router...  We're using a 7204 at our remote site over a Frame T1 to a 4500.
Gotta love fighting with IBM!!!

Denise,
Have you experienced any problems like Wes Keller describes below with the
configuration you have been helping me with? Also is there anything that I
need to stay away from to avoid problems?

We had similar problems with a 5494 and 2501 routers. Tech support at cisco
talked me through setting up DLSW+ and that fixed the problem. If you are
already using DLSW+ then you can try increasing the timeout settings on the
5494.
