What is mean about the following alert information?

cisco-3560-GigabitEthernet0/33 - Gi0/33 User defined Receive Bandwidth changed from 10000000 to 1000000000 bps
cisco-4507-GigabitEthernet7/36 - Gi7/36- Configured Interface Speed changed from 1000000000 to 100000000 bps

I did not make any configuration changes,but my alert information inside contains a lot of this information.

Looks like the devices connected to those ports are auto negotiating. You may want to try to hard code both the device to 100/full or gig/full.

Thank you for your answer. Do you know what the situation may have caused the port speed change?

no, too many factors involved. but best practice is to just set both the switchport and the device that is connected to the switch port to one of the following: 10/half, 100/half, 100/full, or 1000/full.

looking back at your original post, the User defined Receive message indicates that someone changed the speed of the port in orion.
