ER8411 - VLAN setting for WAN1 has lower performance than expected
UPDATE: The issue isn't with PPPoE, but with performance of VLAN handling by port WAN1. See replies.
Hello, I've found this bug around a month ago, I have a 10 Gbps Internet service (actually 8 Gbps) that requires PPPoE.
Previously I've been using my old ISP router (ZTE) as ONT, and it untagged the VLAN coming from the XGSPON fiber.
I got a TP-Link XGZ030 ONT and that's when I found the issue. Using the VLAN option in ER8411's WAN configuration disables PPPoE acceleration and the speed is limited to around 700/700 Mbps and 100% CPU utilization. Then I got a XGSPON SFP+ stick from FS-com and the same speed limitation happened.
When untagging the VLAN with an intermediate switch, speed recovers to 8/8 Gbps. I've tried FW versions 1.0.3 and 1.1.0 without success.
Let me sum up:
PPPoE HW acceleration works properly when:
- [XGSPON OLT] --- {VLAN20} --- [ONT ZTE 8648P (Untag VLAN20)] --- {NO VLAN} --- [ER8411 (SFP+ WAN1, PPPoE)]
- [XGSPON OLT] --- {VLAN20} --- [ONT XGZ030] --- {VLAN20} --- [Switch (Untag VLAN20)] --- {NO VLAN} --- [ER8411 (SFP+ WAN1, PPPoE)]
- [XGSPON OLT] --- {VLAN20} --- [ONT FS-com] --- {VLAN20} --- [Switch (Untag VLAN20)] --- {NO VLAN} --- [ER8411 (SFP+ WAN1, PPPoE)]
PPPoE HW acceleration seems disabled (100% CPU and limited to 700 Mbps) when:
- [XGSPON OLT] --- {VLAN20} --- [ONT ZTE 8648P (Untag VLAN20)] --- {NO VLAN} --- [Switch (Tag VLAN20)] --- {VLAN20} --- [ER8411 (SFP+ WAN1, VLAN20, PPPoE)]
- [XGSPON OLT] --- {VLAN20} --- [ONT XGZ030] --- {VLAN20} --- [ER8411 (SFP+ WAN1, VLAN20, PPPoE)]
- [XGSPON OLT] --- {VLAN20} --- [ONT FS-com] --- {VLAN20} --- [ER8411 (SFP+ WAN1, VLAN20, PPPoE)]
I'd like to use my FS-com XGSPON ONT and I cannot untag the VLAN with it, so I need the ER8411 to perform this task well. Feel free to ask any topology details.
Regards.
P.S. I would also like to be able to unset a VLAN ID for the WAN secondary IP address (192.168.100.2). This way I can route my Internet service with PPPoE through VLAN 20 and access my ONT config with static IP with no VLAN (192.168.100.1).
