Port flapping has many causes...what devices are connected on flapping ports (I see many ports actually flapping)?
What is the output of show power brief ethernet x (where x is the port's number) related to flapping port?
What software version is running your Aruba 2920?
Admin edge generally would be set on any port connected to access device (such as an host) with the command spanning-tree ethernet x admin-edge-port but, nevertheless, you should investigate first why a port flaps while another doesn't...that's because the admin edge option just sets the involved port into immediate forwarding state (shortening the typical Blocking -> Listening -> Learning -> Forwarding spanning tree phases).
Eventually you would provide sanitized running configuration to help diagnosing what is going on...
