Hello,
hope this is not too offtopic but with more and more cheap (non-cisco)
atm gear popping up on ebay mayebe this issue could be of interest to
this community.
Has anybody gotten atm pvc autodiscovery to work with Marconi
(former FORE Systems) ATM switches? I am having a hard time here
to get it done. ILMI is working fine and a debug "atm pvcd" tells
me that it has discovered 8 PVCs on the link. But the PVCs never
show up in 'show atm pvc' - just the ILMI PVC is showing up.
The PVC itself is working fine when manually configured. Classical
IPoverATM with ARP-Server is also working fine.
ATM switch is a Marconi/FORE Systems ASX-200BX running FT6.2 Software.
If anyone of you got it working, what Software version was running
on the ATM Switch ?
Is 'atm pvc autodiscovery' a cisco proprietary functionality only
working with cisco atm switches? I've included a few debugs that
show that the Router is querying ATM switch for its PVC tables and
the PVC numbers actually show up in the responses from the atm
switch.
Thanks a lot !
Reinhold
The setup is as follows:
