Yes the second. So it only works with SNA .
ACK
I don't think DLSw being SNA only is a problem. I say this because I think DLSw
requires TCP/IP connectivity. Thus you already have TCP/IP connectivity to the
mainframe.
Yes its DLSw.
Was demonstrated at the recent DEC Legacy event..

Is it proper to say that SNA is the protocol that is carried across the DLSw over
IP? Is it also what's carried over the SDLC?
No, I was thinking if you had an older mid-range
box with no TCPIP...
Okay.... I'm lost.
If there's no Cisco box with Twinax and the host doesn't have TCP/IP, how are
you going to connect things?
SNA across Token Ring and / or Ethernet?
#confused
Real SDLC from the CISCO
