I've just bought this and testing it with ADSL.

The ATM side seems to come up (the light is solid green indicating SHOWTIME) but I can't get an IP on my CPE (which isn't a Mikrotik).

I've created a VLAN interface (VLAN 6 according the the ADSL fallback table in the doc that comes with it for VCI/VPI 0/100) and then configured a PPPoE client, but it doesn't seem to authenticate.

Has anyone used it with ADSL in NZ?

ADSL needs PPPoA, also no VLAN for ADSL

You may struggle if the Metanoia SFP-V5311-T-R doesn't support PPPoA

As I understand it, the module is an ethernet to ATM bridge. There is a VLAN to PVC mapping table included with the documentation provided with the module.

What you're saying applies to regular CPE which supports ADSL, not this specific module - I think I need someone who actually owns one.

Not correct. You need to address the module on a different VLAN depending on which ADSL config you are requiring.

@mabnz, you are correct, it is VLAN 6 for 0/100. The issue you are most likely having is it is using LLC encapsulation, not VC-MUX, which is almost certainly what you need.

Thanks! I know they aren't the same, but do our DSLAMs not support both?

Ideally there'd be a 0/110 VC-MUX config so you could drop a VLAN10/PPPoE client on it, but no...

If it does pppoe to pppoa translation thats pretty cool.

Otherwise I'd look to do 0/110 vlan 10 pppoe. Does depend on provider support though.

I dont recall 0/110 in the vlan configuration options sadly.

I don't believe these will work with ADSL unless you're with a provider who supports EUBA PPPoE on 0/110 rather than ATM.

I think @runningman might be correct in that it's not working cause of the missing VC-Mux config.

Hi I have played with one on VDSL, works fantastic, however all the research I have done indicates that the default map config as supplied will not work with ADSL on Chorus's setup.

It would be good to see if we could adjust that, have not had the time to sort out the requisite tool to adjust the current config map. Anyone who has the time to chase that through, I would be keen to hear of the outcome.

Hi, ok so this thread had prompted me to spend a few minutes, it appears from a thread on the Mikrotik forums back in 2017 that Procend who brand/sell this module in Europe that the table is not able to be modified................ but in typical Geek

fashion that should be a red flag to a bull, so someone will have found how to tweek it.

The official specs show this module as supporting ATM but's it's (thankfully) been years since I had anything to do with ADSL so I'm a bit out of date with the local specifics.

Something to keep in mind with the V5311 - you must set your SFP port as 1Gbps with auto-negotiation off.

I have one of these (using it right now) but have only used it with VDSL.

Hi Michael, you never mentioned how speedtests compared to your past solution.

I previously used a Cisco 887VA.

The VDSL speed test is lower by a few Mbps but I have gained a 3ms latency improvement.

If the OP wants a decent PPPoA solution I'd suggest they try a Cisco 857, 867, 877 or 887.

@mabnz

I have just gotten off the phone with an engineer who has knowledge of this product.

At present, the 5311 is only suitable for VDSL, however an upgrade is being developed which should hopefully enable it to work under New Zealand conditions for ADSL with PPPoE.

This is early information so no release date or confirmation of suitability for ADSL/PPPoE is available now. Whether any upgrade can be done DIY or the V5311 needs to be returned is not yet established either.

This module is not suited to ADSL with PPPoA and no upgrade is for this is planned.
