Netgate SG-3100 LEDs

dpasadis

Thanks msf2000. I appreciate your contribution.

I like your first suggestion (and your second for different reasons).

I've done a lot of work on operating systems, including Unix/Linux, so I might be able to figure out #1 without spending a crazy amount of time on it. If I get a good result, I'll share it here.

Cool thread!

I wrote some more comprehensive documentation on my blog, which explains the timings in more depth. https://www.zacharyschneider.ca/blog/post/2019/12/customizing-leds-netgate-sg-3100

Hope it helps!

I took some of the information in this article and wrote a script that sets the LED colors based on network interface state and bandwidth usage.

@jchonchi Sounds useful. Does the script work as intended?

I'm a complete moron when it comes to coding, so my risk tolerance is near zero.

@jchonchi i am using the script, works like charm. Thanks

Very helpful thread.

I re-wrote msf2000s script as a sh script and generalized it a bit.

I use the left (circult) and middle (square) LEDs to monitor my two WAN connections.

I also toned it down a bit so I don't need sunblock.

@msf2000 This was working for a long time in 2.4.5 -- but doesn't seem to anymore in 21.02.

@bldnightowl said in Netgate SG-3100 LEDs:

@msf2000 This was working for a long time in 2.4.5 -- but doesn't seem to anymore in 21.02.

After reading the release notes I’m guessing this is the reason-


Several abandoned and deprecated packages have been removed, including:

OpenBGPD (use FRR instead)
Quagga OSPF (use FRR instead)
routed
blinkled
gwled

@bldnightowl
What the crap is NetGate doing with version numbers? Breaking their own products? I don't plan to update past 2.4.5. Guess I'll read up on what's going on later.

As for my script, sorry, you are probably on your own if you upgrade to v21.

@bldnightowl Check that you're using the right GPIO device:

sysctl dev.gpio | grep .led.

When I upgraded to 21.02/2.5, the GPIO device changed from 0 to 2 on my SG-3100.

@wgstarks The blinkled and gwled packages aren't needed for the SG-3100 LED driver, those are for controlling the LEDs on ALIX and WRAP platforms.

jchonig

@z4xh What is the relationship between the output of that command to the numbers I provide to gpioctl? I'll update my script to make use of that and test it on 2.4.5 while they figure out the issues with 21.02.

Thanks.

@jchonig This github commit explains it best: https://github.com/justdaniel-gh/sg3100customleds/commit/ddbf412cb1cf3ba32160972e2177c356611ff57f

The probe order of the GPIO devices changed in the newer version of FreeBSD since more of the on-board devices are supported now. It wasn't intentionally moved or anything.

Yes, it looks like the script doesn't set the gpio device so it defaults to using device 0 which is no longer valid. You need to set gpioctl to use /dev/gpioc2, for example:

/usr/sbin/gpioctl -f /dev/gpioc2 6 duty 0

I've updated my script and put it in a git repo. I'm still only running it on 2.4.5 until 21.02 is stable on the SG-3100.

jchonig

I've updated my script for the gatewaystatus returned by pfSense+ 21.05 and to allow the specification of the gateways to monitor on the command line. It's no longer necessary to edit the script.

In my case the cron command looks like:

/root/gw_leds -v -a WAN_OTTC_DHCP -b WAN_EA_DHCP

Which means that LED a (left-most) monitors WAN_OTTC_DHCP gateway and LED b (middle) monitor WAN_EA_DHCP gateway.

jchonig

I bit more hacking on the script today.

I made it more modular.

I disable PWM mode on any LEDs we are using which disables the slow blink. Maybe I should make that configurable.

I also added -A, -B and -C options to set a fixed color for a given LED give a list of 3 comma-separated numbers. Mostly for testing.

Off to do non-computer stuff on a Saturday.

wgstarks

New script worked great. I only have one gateway so I used

/root/gw_leds -b WAN_DHCP -A 0,0,16 -C 0,0,16

This gave me light blue (undetermined) for first and last led and current status on the center led.

The only issue I had was that I couldn't remember how to upload a file to root.

SFTP of course. I just don't do it very often.

jchonig

@wgstarks I decided not to be too clear on that to make sure people knew enough of what they were doing to figure that out.
