Ying,
Please post your topology. Do you have access to move cables around? and also l
et me know if you have one switch.
thanx,
chris hugo

Have you tried dspu on serial line? I could not get the dspu to go across
the DLSW cloud when I replace R1-R2 and R3-R4 link with serial lines. I have
no problems to set up dspu just between R1-R2 with either FR or X.25 (dspu
does not support HDLC, but it does support X.25). When I added the DLSW into
the picture, the dspu would just stay inactive. I also tried to put serial
line and the ethernet in the same bridge group and start dspu from the
ethernet, but got the same result. Please let me know if you have different
results. I'm assuming there will be a FR cloud in the core and psdu host/pu
to dlsw router can be anything.
Thanks,
Chang
