tx rx fp rx dropped pppoe account

Stop traffic on pppoe-out1 who stuck on be running but not transfer any traffic. Similar situation is at l2tp tunnels, after reboot the one direction is not work and tunnel must be re-enabled and this can be happend with low probably but I see this in few mth again for years.
.

The FP Tx = 0 ?

It’s symptom. Autor of post cannot write other difference on working and stuck connection without this Rx=0.
.

That’s normal.

On links who have small traffic yes but not if you have got constancy traffic. You mean main optic links in ocean have got sometimes Rx=0 ?
.

While connected to a router which is mostly idle, from outside.:
And after being connected also to a device behind it so the firewall has to forward a few packets:
No issue.
ppp-wan wasn’t reconnected since boot. (link downs = 0).

Congratulation. Not every ROS and RB works well, I hope your luck will be permanent.

Weird. I have not seen something like this with PPPoE and we mostly have PPPoE around here, almost all ISPs offer PPPoE connections.
A config export wouldn’t hurt, before digging more. As for the FP counter you’d have to be sure your fastracking rules are properly set and you don’t have your traffic bypassing it
So, yeah, not very reliable to script against it.
Also, your joke about the optical ocean link, RX no, it might not be 0. But he was talking I think of FP Rx (actually I’ve seen it’s FP Tx) which is not the same thing.
But, he didn’t give many details. And in the ones he gave I have not seen RX 0, or TX 0, only FP Tx 0 which as i’ve tested above, can happen in a normal use case.

YES, I agree.
Question please ask to Topic author about export, version his ROS and RB, I try do at all I could.
Topic autor not provide properly data to create right script then I give him my “better Netwatch solution” because he have only one wan interface and this is good way to solve his problem.

P.S. Maybe problem will be solve by upgrade and he have got mAP as main router but all this are “maybe”.

Alaqmar12121 · January 12, 2020, 5:46am

@Sib tested the code over three days. Please check attached screen. even with netwatch setting, the internet down and back with manual disable and enable the pppoe client account

Alaqmar12121 · January 12, 2020, 5:48am

Also i refer back to first suggestion by you @Sib
I add below hope it will disable and enable pppoe account once traffic went to 0

/interface set pppoe-out1 disabled=yes
:delay 25
/interface set pppoe-out1 disabled=no

What you think?

SiB · January 12, 2020, 12:17pm

First, If you have both netwatch with the same

host to check
comment

then this stops works because a down-script read and search a proper status since from only one netwatch with upper condition. Now he not work properly.
Please stay only one netwatch with this comment.
Netwatch haven’t created a schedulers after DOWN happend and not do a future fix work.
or change the DOWN-sctipt to this one who check additional the ENABLE netwatch:

About Rx=0 and action re-enable.
It was a first try but a “Traffic Monitor” detect you a “Rx=0 per 1 second” even when pppoe is working fine. This means this is not good way.
If TM have got option like… 20x happend = 20s with Rx=0 then run script - this will be your solution but TM not have build that counter.

If you fix comment in not active netwatch then you receive one of the best watchdog base on ping in this forum and realy you not must cheat with TM who cannot give you a state UP to reset or dec() external counter.

Alaqmar12121 · January 16, 2020, 5:26am

I have notice when script initiated, there is so many disconnect until authenticated and connected. Is it normal?

SiB · January 16, 2020, 8:53am

I am not using a PPPoE but with other VPN-s it’s common/often.

sopyan0807 · January 26, 2020, 3:45am

I think the Traffic Monitor Tool can do it

SiB · January 26, 2020, 2:51pm

sopyan0807

TM run’s every seconds and it not check past results like NetWatch.
This means your scripts with delay command can be run multiple times. I hope now you know that TM cannot have a any delay in his script. This should be commands who run finish before 1s time.

andyh747 · April 27, 2021, 1:35pm

I’m trying to use Sib’s script to monitor and then action disabling/enabling the LTE interface on a LHG LTE6 unit.

I’m not experienced with scripting but I simply copied and pasted his scripts. How can I post my config so you can check it?

andyh747 · April 28, 2021, 9:40am

OK I’ve posted my config below. If someone could have a look to see if the UP-script and Down-script is correct that would be appreciated.

I was getting script run errors with the log showing not enough permissions. I ticked the box not requiring permissions and the scripts are now running when the LTE connection goes down. Just need to fully test now on a live setup.

Thanks SiB for posting the scripts and all the work you’ve done on it.
