show controllers VDSL - error counters

[JoeyJoe]

Hi guys,

I am performing the command "show controllers VDSL x/x/x" in an ISR4300 to verify CRC and Header error counts. I noticed the values increase but also decrease over time. What would be the reason for the error count to decrease?

Ps.: No type of clear counters has been performed.

Thanks in advance.

Hi balaji.bandi,

You're right. I do see the ADSL reset about 3 days ago. I assume the counters reset everytime that happens then.

Thanks a lot!
