I’m trying to understand when my router discards packets (e.g. the output interfaces cannot handle more traffic).
As you can see in the attachment, I was sending 25Mbps from ether1 inside the router, that was expected to be routed out on pppoe-dati (that it’s attached on wlan1).
Unfortunately wlan1 can handle just ~10Mbps, and as you can see in the attached picture, the router is blackholing ~14Mbps of traffic.
I was expecting the counters rx/tx-drop to increase on one of the interfaces involved but nothing happened .
Do someone know where are the counters that I’m looking for?
As the OP says pppoe-dait uses wlan1 as transport interface, it doesn’t seem plausible unless there was some mysteriously efficient compression. Is compression set to yes in the ppp profile?
It’s simply the interface wlan1 that it’s not able to dequeue from the interface queue as fast as pppoe-dati is fillling it
I will double check the configuration of the pppoe but I doubt that compression is enabled.
Just to be clear, my laptop was connected to ether1 and was generating traffic towards a destination reachable via pppoe-dati (that is attached to wlan1)
