Hi all... (Posted on both the Linux-390 and IBMVM lists.)
I have a client who is putting up a SNA terminal server on Linux (tn3270 via TCP/IP to the terminal server which then connects it to VTAM via SNA out out the other side... The TCP/IP traffic in is easy via an existing vswitch. I'm considering options for the "best" way to route the SNA traffic... Several will (should) work, but I'm wondering if anyone has done it and if one way is better than another... - They have a vswitch today, but it's layer 3. And because of other production traffic on it, we can't knock things down, redefine it and restart. So that choice is out... - We could set up a new vswitch as layer 2, but is it worth it to set up a vswitch for one userid? - We could also dedicate an OSA attachment (just 3 unused device addresses, not the whole OSA) to the userid and let it just run that connection direct to the OSA and let Linux activate the layer 2 support. - Also is there any benefit to using a particular OSA card? Is it better to send the SNA traffic over the OSA that is used by VTAM (will the OSA route the packets directly to VTAM without going out on the net like it does with IP packets)? (If I use the same, doesn't that mean the MAC address of the sender and receiver will be the same?) - And lastly, since this is MAC address to MAC address, will the default MAC address VM gives me work, or do I have to build one of my own? Thanks for any suggestions...
