We are getting this issue always ARP Cache Poisoning attack and TCP Port Scanning attack  please check the below error check what is solution

[Marcos 5,733]

ARP cache poisoning may occur if a computer has more network adapters sharing the same IP address for load balancing or if there are devices with identical IP addresses in the network. If you trust the device, create an IDS exception for the detection. The same applies to the TCP port scanning attack detection; if it originates from a trusted devices and you know that it can scan remote ports for legitimate purposes, create an IDS exception.
