Hello friends
I have the following problem, some CPE when I enable to do PPPoE in the vlan it simply connects but loses constant packets, giving a rate of up to 85% of loss, exchanging the CPE for another new one of the same model starts to work correctly.
Solution attempts:
* Different firmware versions.
* Most cases being from Disc Lite batch 822 but I've had cases with other models.
* Configured Vlan's in bridge, in trunk the same problem occurs.
* In access same thing.
* Bridge configured without vlan filters.
* Mtu of the PPPoE concentrator.
All these attempts were failures.
Remembering that if you do the routing directly on the equipment that the CPE connects to, the problem disappears, the problem only occurs when it is in vlan.
If anyone can help me, I will be very grateful.
