Re: How to understand the fabriclog output

Hi,

As you don't state a reason why you what to know or what we are looking at...

Are you looking for general info on how to read this, if so I can also suggest the TS300 course.

Or is there something specific in this logs you want to know, looks like port14 is flapping, what is connected to that port and how is that device affected?

Re: How to understand the fabriclog output

yes port was gone offline for 4 days and 5th day it was came online with out any issues...also after online cleared the errors using statsclear and startedmonitoring that port.However did not see any errors or any flapping..I also checked with my vendor he said haven't done any changes. I am also sure that haven't done any changes.

Here very much interested to know what happend and how the device got affected & how it came online automatically.

Re: How to understand the fabriclog output

How you're devices were affected is easy, you lost an ISL and therefor reduced bandwidth/availability.

The how it come online automatically, there is no such thing that I'm aware of.

Most likely something changed on yours or theirs end and then changed back or there was a fiber cut somewhere and restored. Even if they state nothing changed doesn't mean that they are talking the truth (or know it).
