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...

Nope, attached above output with Working & Non-Working site.
ADSL2+ = manual mode configure (non-working)
AUTO = auto mode (working)
05-25-2017 11:50 PM
Hello,
try and check with the ISP what DSLAM they use at both sites.
05-26-2017 12:14 AM
Hi Georg,
DSLAM is checked from ISP site? Can we detect it from router ATM interface itself?
05-22-2017 06:10 PM
Anyone having similar issue which solved?
Please assists, thanks alot.
