I did some more debugging with the following findings on Friday:
- PPPoE client PADI packets send out the network are no longer received from PPPoE server
- changing SFP module brand does not resolve this issue
- unplug / re-plug SFP modules does not resolve this issue
- soft-reboot WS-250-AC does not resolve this issue
- hard-reboot WS-250-AC does not resolve this issue
- increasing the port MTU from 1528 to 1556 does not resolve this issue
- disable "Storm Control": Broadcast, Multicast, Unicast filters to "None" does not resolve this issue
- disable Discovery protocols does not resolve this issue
Downgrading to v1.5.16 does immediately resolve the issue.
If you have PPPoE discovery working on latest v1.5.22 via SFP links please share details on your setup.
Sounds like in my troubleshooting its related to the SFP, is there an option for you to use ethernet directly to the switch and see if the issue goes away?
