This basically means you have DDOS Cpu protection enabled.   There should also be what type of ACL is being created in the log.  

example----

11/04/2019 14:32:34.15 <Info:DOSProt.AddACLOK> MSM-A: Added an ACL to port 1:5, srcIP 172.16.150.61 to destIP 0.0.0.0, protocol udp
11/04/2019 14:32:34.04 <Info:DOSProt.PktCntExcd> MSM-A: Notify-threshold for L3 Protect packet count of 3500 reached 

 

This means that more than 3500 PPS hit the cpu and the system wrote an ACL to slow this down and protect the CPU of the switch.   If this is happening a lot then you need to figure out what is causing so much traffic to your CPU… 

 

Here is info about what hits cpu … https://extremeportal.force.com/ExtrArticleDetail?n=000015071&q=what%20patckets%20on%20XOS%20switches%20hit%20the%20CPU

Is there any other way to observe what type of traffic is causing the overload?
