WAN "loss" question
-
Got it. Thanks!
-
One more thing, so the "member down" setting would be the most preferred from the 4 choices if all is well in my Internet connection?
-
This is where I'm unsure. :-
My guess is that "member down" is most fault tolerant, it will continue to use a slightly flaky connection.
If you have some application that is very sensitive to latency or packetloss, like VOIP for example, you might want to have connections excluded from a group at the first sign of a problem. In that case you would use one of the other settings.Steve

RRD Graphs and ther ethe tab "quality" will help you know, how high the latency and the poacket loss was when the gateway went down.
so you can adjust the low and high watermark. -
Using "member down" would only stop using a WAN if the link is lost on the port.
Most WAN failures do not result in a loss of link on the physical port - the loss is upstream somewhere (like on the other end of your modem/CPE). You want "Packet Loss or High Latency" in almost all cases.
If your WAN tends to be a bit lossy, as my Cable line is, even when it works fine, you can adjust the parameters that trigger the alarm under the individual gateway. So go to System > Routing, edit the gateway for WAN, and in the Advanced settings, increase the Packet Loss thresholds. For my Cable interface I have to use 20/35 or so.

But in that case, high latency would be a problem for me since the latency increases when I download using Newsgroups. Is there a way to change the latency threshold as well?

Yes, the setting is in the same place. Edit the gateway, under the advanced settings there are tweaks there for the latency, loss, etc.

What is the default value for "Down" ?
Could it be possible to enter the default values in the description for future snapshots ? -
I don't recall the defaults, you can check /var/etc/apinger.conf to see what's there.
Having them in the description would be handy.

Thanks for the info.
