Re: help in reducing cpu when using NAT & Policy map

Hi

so, how many nat translations does this one user has?

I ve seen one user using 4000+ nat translations, which caused the cpu of a small router to go to 99%

show ip nat trans

show ip nat stats

that way you can see how many translations the user has.

If you want to restrict i

ip nat translation max-entries host

Like  f.i.

ip nat translation max-entries host 10.1.1.1 500. This user can now have 500 nat translations
