(ENI) 155 Mbits/s PCI bus ATM NICs. I have installed 2 ENI PCI Bus 155 Mbits/s ATM NICs per router. I have 2 ALTQ shadow PVC interfaces (pvcsif) namely pvc0, pvc1 configured per machine. Over a time (say a few days) I find that typicaly one of the pvcsif becomes unserviceable, I cannot ping A->B or B->A from either end of the pvc. ping reports 100 % packet loss. The receive lights on the ATM NICs show as green and therefore seem to be receiving cells ok. I am running GateD 4.06 configured to run RIPv2. When I check the routing tables at A and B with netstat -rn, the point to point route entries seem correct. So don't think its a routing problem. I have returned eight ENI cards (multimode fibre type) to ENI following such problems. ENI tested all eight cards and they tested as OK. I have swapped over to UTP5 cable based cards but the "unserviceable" pvc problem still occurs. Has anyone seen/heard of reliability problems using BSDATM in conjunction with ENI ATM NICs or more specifically using ENI cards with ALTQ pvcsifs ?
