[comp.sys.dec] Need help with DECnet-RSX link level packets

jsamail@gibbon.inel.gov (Jim Albano) (08/03/90)

We are upgrading a distributed data acquisition system, replacing
PDP-11 to VAX dataflow via DECdataway with link level IEEE 802.3
packets to the same VAX and added UNIX workstations.  In addition,
we would like to manage and control the PDP-11s from the VAX using
DECnet.

We found it necessary to change ethernet line ownership on the PDP-11s
to DLX to broadcast the link level packets.  This configuration change,
unfortunately, disables DECnet.

Has anyone managed to  broadcast and receive IEEE 802.3 link level
packets using DECnet-RSX while leaving DECnet operational?  If so,
have you any idea where we may have gone wrong?  We are using
DECnet-11M-PLUS Version 4.0.

Thanks in advance.  Please respond via EMAIL to jsa@inel.gov

like to avoid wasting more time if this dual usage is not available.

If we can broadcast these packets while also using DECnet,
have you any ideas, guesses, etc. where we may have gone wrong?
We are using DECnet-11M-PLUS Version 4.0.  Any suggestions would be
greatly appreciated!
