DEC3920 Quick Review

[dirtyfreebooter]

yea i did upgrade the i226 firmware on my VP2440 to 2.32. i would not upgrade the DEC3920 without Deciso blessing or if i decide to keep the hardware. i am currently trying to run a bunch of iperf3 / packet-sender tests in an isolated setup, see if i can reproduce or if its only the ONT connection.

i put the VP2440 back in use sunday night and of course it has worked flawlessly since then. 100% uptime on connection and ONT, etc

Is the issue reproducible on other ports?

Can you swap igc0 with another port to see if the same drops happen?

If you can confirm the issue on two ports then the next step I'd try after confirming with Deciso would be to update the firmware on one of the ports to 2.31 which is the latest we have publicly available and see if the issue persists.

yea, in my latest tests, i am trying WAN on igc0 and igc1

lol, i226 is such hot garbage, and even more so in freebsd

Another thing I didn't see mentioned here:

Did you try disabling the auto negotiation on the ports ?

What switch is it connected to then?

igc (on other hardware) and Netgear was a bad mix on my end and we replaced the switch with a Cisco for that reason.

On my end I have two DEC750 with igc connected to a Netgear MS510TXPP stack and its rock solid, even with auto negotiation (2.5gig is negotiated).

Router is a Fritzbox and both igc are also directly connected there, no link drops.

I guess it really depends...

it was connected directly to my Calix 711 GE ONT. which is the same setup i have had for > 5 years. and other igc based firewalls, odroid h4 ultra, aliexpress mini pcs, protectli vp2440, etc. but of course DEC3920 is different and has a different i226 firmware then all the others.

so i put the DEC3920 back in lab mode, isolated with a linux server on both sides. i put over 10TB of traffic through, and not a single issue. i even put a 1gbe switch on the WAN side so that the 2.5g wan would autonegotiate @ 1 gbps.

so last night i pulled the power from the ONT for 5 minutes, i know, its dumb. put the DEC3920 back, powered back the ONT. going to see if that helps, as i was not able to reproduce the behavior. if it goes out again, i will try putting that dumb switch in between the ONT and WAN.
