WiNG AP adoption over PON network

leoslav — Thu, 09 Jan 2020 03:38:17 GMT

hi,

Does anybody had experience any MiNT communication issue behind a PON network?
Our customer is implementing a Passive LAN solution (Enterprise) and wants to have WiNG APs connected at their ONTs.

We found that those ONTs are unable to handle MiNT Level-1 traffic between RFD APs - Level 2 communication between RFDM & Controller is ok (Layer 3)

Any clue? Any workaround?

PON vendor is working to solve broadcast & level-1 behavion inside PON environment.

We are seeking for workaround solution to have the APs adopted.

Cheers,

Leonardo

leoslav,

Ensure that ether-type 0x8783 is allowed on the PON.

What is the MTU value on the PON?

Hi Chris,

At OLT side (PON) MTU is set to 1500.

We're investigating with PON vendor about ether-type filtering at OLT box (we suspect that this device may be filtering Level-1 frames).

All Level-2 frames (UDP) are being properly forwarded between RFDM & Controller.
The issue is persistent only at Level-1 environment.

Now I'm looking for any other workaround solution (perhaps L2TP?) to "bypass" Ethernet switching over PON environment, to speed up AP adoption.

Important that we need MINT level-1 communication between the APs from same RF-D.

Cheers, Leonardo

So, you’re level-2 MINT frames are going to be IP based. Level-1 MINT is possibly layer-2...which is where the need for allowing ether-type 0x8783 traffic comes in.

All APs have an IP address on a common management interface?

And yes, since it sounds like you’re setup with a Distributed topology with multiple RF-Domains (not controller managed) then you need MINT level-1 communications to work between the APs within an RFDomain….otherwise things won’t work so well. 🙂

Perfect, as we are looking forward. PON vendor is investigating to find out a solution to allow 0x8783 traffic in layer-2 perspective.

I'm looking forward a "Plan-B" in case they are not able to find out a solution to allow Level-1 & MLCP traffic…

Yes, all APs has IP addresses & connectivity to the controller (customer has a VX9000)

Tks 🙂

hi all,

Just to close this thread: PON vendor has issued a patch to allow packet forwarding for MINT/MLCP.

We guided them to use Ether-type 0x8783 (Layer-2 packets) or UDP 24576 (Layer-3 packets) as triggers to match as MINT flow.

After that, we had successful MINT L1 neighbor formation, MINT links & adoption.

Smart-RF and another features based on MINT/MLCP also are working successfully.

Great feedback, leoslav!

That’s excellent news. Glad you were able to get that patch and have it working now.
