My WAN interface is via PPPOE to a Gbit fiber network. This weekend a hedge cutter shredded the line up the street so the fiber has been dead for a couple days. I see in the /var/log/messages that netifd sees that the interface is dead and keeps retrying to connect it. When pppd exits with a failure, it sleeps for 10 seconds, then netifd does an ifdown followed by an immediate ifup on the corresponding eth interface. It seems like this rapid down/up on the eth port eventually kills something on my br-lan because after a few hours of these retries, devices on my wifi network can no longer talk to devices on my wired LAN.
Right now I’ve manually done an “ifdown wan” to stop the endless retries, but I’d like some kind of retry so that eventually it can automatically bring itself back up. I just think I need a way to tell netifd to pause between issuing the ifdown and the ifup. Does anyone know of a way to configure it to do that?
Here’s what I’m seeing. Notice at 13:44:05 the wan interface is disabled and then immediately enabled again. And the same thing happens again multiple times:
