Re: 887VA VDSL2 configuration

cg1network · ‎10-12-2013

Hi

I have a Cisco 887VA router that I'm trying to connect to a VDSL2 service.

I'm getting this error when the VDSL2 service is plugged in:

%VDSL_DAEMON-4-TRAINMODE_NOT_SUPPORTED: ATM transport mode is not supported on VDSL2.

Here is the controller details:

Interface can't train up, try another router for verification or check with telco.

I don't have another cisco router with a vdsl interface, i have tested the basic router that was provided by my ISP and that connects fine.

paolo bevilacqua · ‎10-14-2013

That's what I meant, try updating IOS and/or VDSL firmware. Worst case you have to use ISP router in bridge mode and cisco PPPoE on Vlan interface.

FWIW...

I have an 887VA and VDSL2 (PTM) from an ISP working.

They don't use PPPoE so I'm not sure this will help any that require it.

All I had to stop using ATM interfaces and use interface E0

(no subinterface as recommended elsewhere) and then

controller vdsl 0

operating mode vdls2

James Neilson · ‎10-14-2013

Try:

conf t

wan mode ethernet

exit

controller vdsl operating mode auto

cg1network · ‎10-14-2013

I have updated the VDSL firmware and am now getting

%VDSL_DAEMON-4-TRAINMODE_NOT_SUPPORTED: UNKNOWN transport mode is not supported on VDSL2.

I have changed the vdsl operating mode to auto, but the "wan mode ethernet" isn't a recognized command

paolo bevilacqua · ‎10-14-2013

That is not an error just a warning and is not related to the problem.

Unless you can get Cisco Tac into looking why the router doesn;t sync with the particular ISP DLSAM, you will need to use the ISP router as mentioned above.

I had the same err-message this morning, in my case i did the following and fixed.

(config)#controller vdSL 0

(config-controller)#operating MOde adsl2+

there are other options under this tab, apply the one fits your SP line or try all 1 by 1 till its up-up

adsl1 ITU G.992.1
adsl2 ITU G.992.3
adsl2+ ITU G.992.5
ansi ANSI T1.413
auto auto detect mode
vdsl2 ITU G.993.2

I have finally got it working, my ISP sent an engineer and he fixed it in 2 minutes.

My ISP uses VDSL2 over PPPoA and apart from the cheap router they supply no other router supports this, they changed my line to PPPoE from the MSAN and it connected.
