Hi All,

 

Can anyone explain what the meaning of below message in policy lookup.

 

Policy lookup matches the implicit deny policy. No explicit policy exists from source interface "switch_port5" to destination interface "port1" as determined by a route lookup to "142.250.67.174"

 

thanks

There is no policy configured that matched this traffic.

Hi,

 

Can you explain what the  implicit deny policy and explicit policy is.

Hi @Umesh 

Implicit deny policy is the "default policy" configured on the system by default. You cannot edit/modify this. This policy will drop the traffic that is not matching any other policies configured by you/firewall-admin.

 

All the firewall policies that are configured by you/firewall-admin called the explicit policy and they are placed above the implicit deny policy. Policy match happens from top to bottom in other words the explicit policies are checked first and if there are no match traffic will hit the implicit deny policy on the bottom.


I hope this helps.
