Hello Ruben,

Is the CGN NAT configured and running already? License will be allocated and active once the feature is configured and running. Not sure with CGN NAT, but should be the same behavior I think.

Hi Rivalino, I test with you say, but no see change in show.

my test.

ping from Edge to Internet (Edge-Core-Crs) ---->

the NAT is ok, the linecard generate the NAT. OK

But I don`t see that Licence is Active. same result that first show.

At present, CGN s/w does not grab the license.

As long as you've installed the license, you're fine.

Hi Somnath, I understand you request, if I have Licence for 5MM of traslation why I don`t Active Licence. how I safe me this operation is ok and not have  a problem in production.

Thank.

Hi Ruben,

You should not have any issue in production related to CGN/CGv6 license (CLI may not show the status correctly because of the reason I indicated earlier).

regards,

Somnath.

Hi Somnath, I have in production my CGN but yet I don't see that license be  active with traffic, you have some idea because  this.

Hi Ruben,

CGN licenses will not be shown as active for now. So, you can ignore the license state for now as long as you've installed the required licenses. It should not cause any issue on traffic.

Somnath.
