Port up and down

[akhon0001]

 I have a switch 3560g that has cameras connected to the ports.
Hikvision camera model.
and ports are constantly changed state to down and up.
How can I find out the reason?
The cameras work correctly.

Post the complete output to the command "sh interface G0/10 controll".

Nothing wrong with Layer 1.
The camera going down and up could mean a hardware issue.

[akhon0001]

Thank you,

but checking showed that there are no problems with the camera.
Please tell me, maybe it’s such that some packets come in from the camera, in which there is a message about the disconnection. Is it possible to somehow check which packets are interrupted by communication, for example, using debug?
I need to understand why this is happening, because I already have 7 such cameras, and the messages in the logs already reach 16,000. Each port to which the camera is connected sends messages to the logs

Hi,

    Is the camera using PoE from the switch (from the log message, looks like not, but just to be sure). I see way too many multicast/broadcast packets from the camera, can you configure it and and disable those services doing this? Your camera is supposed to send the footage via unicast, right? 

Regards,

Cristian Matei.

Adding to other mates comments.

Do you have any auto discovery running in the network, i have seen some issue around the cameras

Some how when the scanner try to scan the device IP address, it drops and reboot some how (may be not the same case with you)

[akhon0001]

I don't have any auto discovery running in the network ...

[Leo Laohoo]

Is the camera getting a valid IP address?

[akhon0001]

The camera has a static address, everything works correctly.

good afternoon

The cameras are powered exclusively by the switch
(Most likely, many multicast / broadcast packets come from the camera) - how does this affect the drop in interface? No storm-control policies are configured on the interface.

When the interface drops the power does not drop exactly. Notice the time interval when the interface changes from down to UP, 3 seconds. I do not understand what it means.
