[c-nsp] ASR9K VSM

[Mohammad Khalil]

Dears
I have installed VSM on ASR9K for NAT44 CGN
I can see a lot of drops in the output of show cgn nat44 nat1 statistics 
RP/0/RSP0/CPU0:NAT1#show cgn nat44 nat1 statistics



Statistics summary of NAT44 instance: 'nat1'

Number of active translations: 4079397

Inside to outside drops port limit exceeded: 155093

No translation entry drops: 1617189

I have some questions regarding this if you can assist 

One of the experts told me that number of active translations are 4M (it can be shown from the above output that the number is like that) , is this number per module ? per service ? can I configure extra to isolate this?
inside to outside drops ?
portlimit drops ? I have configured it to be 2048 , should I increase it ? 2048 means for each private IP address there is 2048 available ?

Thanks in advance
