[c-nsp] LS1010 stop passing traffic between ATM interfaces

[Francisco Rivas]

Hi all,

I have a LS1010 (running ls1010-wp-mz.120-28.W5.32a.bin), and I'm having 
some problems with it. Basically, I'm just using it to switch some ATM 
PVC's from one side to another, and suddenly the LS1010 stops passing 
traffic.
The LS1010 isn't part of any ATM network, as far as I know. The PNNI 
stuff is there from several years ago, I just started working here and 
I'm trying to fix all the issues now. The LS1010  were running an IOS 
from the year 1996, so I did an upgrade a couple of days ago, to try to 
fix the problem. When I see that the LS1010 stop passing traffic between 
the ATM interfaces, I do a reload, and the LS1010 starts working again. 
Sometimes, I can even delete the PVC's and put them again on the config, 
and that's enough to fix the issue, but this doesn't work all the time. 
Only the reload works every time.
 The LS1010 is passing little traffic (under 10Mb at peak hours), and 
the config is very simple, so I don't know where to start looking for 
problems. On both ATM interfaces (the ones that I'm using) I see 
incoming traffic, but zero output traffic when this problem arises. The 
Ethernet interface is just being used for admin, not to pass traffic.

This is the config:
