Problem with IRF link detection
Hi
I deployed an IRF topology between two datacentrer over two dwdm fiber links 40gb qsfp+ interfaces. When I configured it, the topology works fine for many month but in a moment I lost one of the links between the datacenters. When the link was repaird the interface didn´t recovery automaticaly. To recover both IRF links, I musted shutdown the interface and undo shut and it allowed to the IRF comes UP with both interfaces again. I have both switches with the last firmware version that I finded

Re: Problem with IRF link detection
Hello,
Is there MAD configured?
Can you please share 'display log reverse' output?
Please mention the time of issue as well.
Thanks!

Re: Problem with IRF link detection
Hi akg7
Thanks for your answer
I didn't config MAD yet
Right now the IRF is working because both links are ok
<IRF212CPACPO>display irf topology
Topology Info
-------------------------------------------------------------------------
IRF-Port1 IRF-Port2
MemberID Link neighbor Link neighbor Belong To
2 UP 1 UP 1 00e0-fc0f-8c03
1 UP 2 UP 2 00e0-fc0f-8c03
I don´t have an evidence right now about the problem because in this moment it is working and i haven´t the log of the moment when it has happened.
Until this moment the IRF have never fail, in amoment only one of the links has fail and went it was fixed then this link did not converge automatically to the IRF again until I restart the physical interface.
Maybe we needing to wait until it happens again and capture the log.
Thanks in advance

Re: Problem with IRF link detection
It seems whole stack didn't have issue. Only one of the irf slot had issue so logs will be present in switch, can you run 'display logbuffer reverse' and see if you are able find logs and if not then collect logfile.log file from flash of the slots.
You can see logfile folder under >dir /all-filesystems.
Go to logfile folder and extract logfile.log file.
Thanks!

Re: Problem with IRF link detection
Hello @Vincent-uy ,
There can be multiple reasons but tts difficult to say the exact root casue of the issue without proper logs and sometime logs also dont have proper data.
Thanks!
