Unable to log interface down in /var/log/messages – OSPF

[Kriti Goel]

Hi,

When I bring down an interface, the /var/log/messages file does not log that the interface is down. When I bring the interface back up, it shows the same timestamp for both when the link is not ready and when the link becomes ready.

Kindly let me know how to proceed further.

Attached screenshot for reference.

Hi Kriti,

By default, fablib marks the dataplane interfaces as unmanaged by NetworkManager. So NetworkManager is not logging the interface down operation. This was done deliberately as having an interface managed by NetworkManager kept overriding the IP address configuration applied by fablib. Please note this behavior is specific to rocky images which enables NetworkManager by default. Ubuntu doesn’t use NetworkManager by default.

We disable NetworkManager on rocky to be consistent with Ubuntu and leave it to the user to change this behavior as they see fit.

 

Thanks,

Komal
