IP Cameras

[zh11]

so we recently upgraded to all cisco 9200 L2 switches and 9300s for our cores and we have been in testing with adding cameras and replacing cameras is where we stumbled onto an issue where when trying to replace a cameras with a different camera but the same IP address the switch would not allow the camera to be seen on our video monitoring software because the switch is still holding on to the former IP address

Only clear mac and arp table. 

Or connect PC to subnet of camera and ping to broadcast of subnet, this force all camera to reply and update arp and Mac table

Clear ARP in 9300 (if your L3 is configured there), it should work.

clear ip arp <camera ip>
