ISR4321 VDSL couldn't detect when configure mode auto

Looi Siew Key

Hi,

 

We have 1 router ISR 4321 which add ATM module into it.

Deploy with "controller vdsl 0/2/0" as virtual DSL interface referring to dialer 1 (to ISP).

 

When configure "operating mode auto" inside "controller vdsl 0/2/0" interface, it doesn't able to detect which ISP protocol is using.

Whenever configured using manual way can work, example like "operating mode adsl2+"

 

Only 1 of the branch causing this issue and temporary running using manual protocol configured. Other branch using auto mode works fine.

 

 

Configuration syntax in ISR 4321;

controller vdsl 0/2/0

     operating mode auto (this command will not appear after configured)

 

Firmware:

IOS XE v03.16.05.S - extended support release

Hello,

if only one site experiences that problem, the issue could be the DSLAM of your ISP. Compare the output of 'show controller vdsl 0/2/0' of the site with the problem, and one site where operating mode auto is working. 

Or post the output here...

Hello,

Is any of the above output belongs to non-working site?

HTH

-Amit

Nope, attached above output with Working & Non-Working site.

ADSL2+ = manual mode configure (non-working)

AUTO = auto mode (working)

Hello,

try and check with the ISP what DSLAM they use at both sites.

Hi Georg,

DSLAM is checked from ISP site? Can we detect it from router ATM interface itself?
