Hardware and Performance / Best way to connect 10GBase-T to DEC740

« on: June 19, 2024, 05:41:04 am »

Tl;DR is, my ISP's "handoff" involves an XGSPON box that only has an "RJ45" jack that is wired for 10GbE. Idk what is the best way to connect. So far my options are:

• 10GBASE-T SFP+ module: I tried the 10gtek one with really bad results (unreliable speeds in one direction - it would go down to double digit Mbps). I'm also worried about heat and power usage as the DEC740 is an embedded appliance and is fanless.
• Media converter
• Unmanaged switch: qnap qsw-308-1c includes a 10gb combo port.
• Managed switch: by far the most expensive option

I like the SFP+ module option, as an extra switch and/or converter is one more point of possible failure, but I'm worried about the heat and power usage on an appliance device like DEC740.

I would like, if possible to get reliable speeds with as low latency as possible. The RJ45 cable I'll be using is cat6 of about 13m.

Hardware and Performance / DEC740 Slow upload speeds on ax1

« on: June 14, 2024, 05:30:41 am »

 First off, my internet speed is 4Gbps both ways and i have a DEC740 (the older model)

For a start here's what my network diagram looks like:

XGSPON <---Cat5/5e cable (yea i know)---> QNAP QSW308-1c <---10Gtek DAC cable --> ax1 port on DEC740

ax0 port on DEC740 <---10gtek SFP+ module---- fs.com OM3 cable--- 10gtek sfp+ module---> miktrotik crs305 <--- Intel x520 card  on desktop.

I upgraded to multi-gig and thus connected ax1 for the first time yesterday. Once I had everything connected, in fact I can get 3800/3800 or more, and have gotten it more than once. However, the issue is, more often than not, the upload speed for speedtest goes down to 200Mbps or even lower. If i do 10 tests 1 or 2 will give 3500+ each way the other will give like 3700/150. I initally had RSS enabled which was causing other issues so I have since removed that.

As for settings, except for an extra vlans on LAN side and adguard, both of which i've been using from the get go without any issues: everything else is standard DEC740 config.

Some notes:

• prior to upgrading to 4Gbps i had a 1Gbps plan, at that point i was using the cat5 cable directly connected to a 1Gbe port on the DEC740 and could consistently get 950+ both ways. This all started yesterday when I connected the ax1 port for the first time (prior to this I had never used that port).
  
• i have tested with iperf3 from the router to my desktop and I do in fact get 9Gbps one way and 6Gbps the other way - I suspect the issue with that latter is because the router isn't able to write to disk fast enough to download over 6Gbps to the disk, which is fine and both are over the 4Gb i'm expecting, at any rate
• I had tested a 10Gbase-T module on ax1, and ended up having the same issues, without changing anything else my upload speeds were suddenly very slow.
• i have connected cable directly from XGSPON to my computer, entirely  bypassing the DEC740 with absolutely no issues.

 so far I've settled on ax1 being broken, possibly. Because everything else seems to work, and I have no other explanation.

ETA: I finally figured out how to physically  connect the router directly to my PC via the problematic ax1 port, and assign it to LAN. I did an iperf test to the router (router is iperf server), I generally don't expect to see more than 6Gbps. The big issue was traffic coming out of ax1 rather than going in, which should be the reverse option (ie my computer recving data) right? i was able to get 6Gbit, or more, which is far more than the <200Mbps i see in that direction to the internet.

So, i have no idea what's going on.

General Discussion / Vlan01: untagged or tagged

« on: October 11, 2023, 12:48:08 am »

When I first ventured into vlans, obviously I didn't know much and was experimenting (I still am very new). I just created vlan03 for my iot stuff. It's worked fine so far. My question is, the switch and my WiFi AP expects vlan01 to be tagged as such but In opnsense, there is no vlan01. The port on the switch to opnsense just tags untagged incoming as vlan01, IE opnsense is on a hybrid access/trunk port. Two questions:

1. Should I change this. Is there any good reason to do so?
2. Regardless of the above answer, what's the best way if I wanted to anyway? The vlan01 IP addresses are already assigned to the parent interface, so I can't just put them on vlan01 and turn it on, so I'd have to connect via serial and then disable the DHCP on parent then turn on vlan01? Or assign another temp address etc.
3. Is there an easy way to copy all nat and firewall rules over from parent?

I have just the defaults. drill and drill -T gives the correct responses when used vvia command line for e.g. facebook.com results in a response of 0.0.0.0
