i have installed routeros 2.9.46 on a Supermicro P4SCi based router and have problems with any NIC i put into the system. the 2 onboard ethernet controllers work fine. they are Intel 82541 GI/PI. i have them also working on an identical board in a different router since about 7 month without any problem. only NIC’s which i put into the PCI slots make trouble. all of them respond to the outside world for about 10-20 minutes. after that i cant talk to them anymore. the router can still see the interfaces and ping them. with winbox i cant see those interfaces either. i can only see the mac addresses of the 2 onboard intel controllers. the link status on the switch is still up and routeros is telling me “link ok”.
i have tried the following NIC’s
RouterBoard 44
D-Link DFE-570TX (I have read about issues with that one)
Compaq NC3131 (Intel SB82558B)
all of above work fine for about 10-20 minuses. all cards have been proven to work on linux on the same hardware and the same switch attached to them. the switch is a catalyst 3500XL. anybody any ideas ?
i would accept a hardware issue if i would have problems on linux (debian) as well. but it works just fine. the d-link card is not ideal, i know. but i used it only to make sure i have tried everything i can. the time after any connection attempt fails is actually not even 10 minutes. i have reproduced the problem numerous times now in a way that any connection attempt fails after just 2 minutes. i will now try single port cards like 3com 905 and realtek cards just to see if it would be a problem of multi port interface cards.
I have had problems with p4sct similar with cards not working in pci slots or just plain stopped forwarding packets. I finally had to stop using on of the cards . We had 2 identical machines and many lan cards (pro 1000/mt dual port) and have seen this happen on both machines , changing cards and everything. It is something internal to MT , Mt could not help me out with it.
