Hi Members,
This is happening on my Cisco switch, and I have no idea why this is happening.
Anybody had the same issue? If so, how did you all fix this, please? Your help suggestion and idea would be highly appreciated.

I am not seeing anything wrong here.
What, exactly, is the problem?
05-02-2024 07:05 PM
This interface automatically goes down and comes back again after few second. this occurs every after few minutes.
05-02-2024 07:45 PM
But look at the time of those interfaces going down/up. This is happening outside office hours.
05-02-2024 12:39 AM
is the port going up and down is the issue - this is normal when the device leave the network (or is this automatically going up and down is the issue ?)
or mac flapping as per the logs ?
what IOS XE code running, try upgrading the latest Code IOS XE - 17.3.6 or higher ?

Hello,
what devices (e.g. Windows 11 client machines) are connected to these ports ?
