Environment

Aria Operations for Networks 6.13.0
Aria Operations for Networks 6.13.0
Aria Operations for Networks 6.14.1 

Cause

The issue was seen after NSXV to NSX T migration.

Default layer 2 rule on NSXV was superseding all the defined rules.

 

Resolution

Firewall rules needs to be reconfigured as per recommendation in the Alert.

The rule created was on NSX V. Post migration reconfigurations of the firewall rule is needed.

Delete or Disable the default rule from the NSX  GUI to have the alert cleared from the Aria Operations for Networks.
