Hi Everyone,

Actually i have a doubt about what that’s exactly means the following entry on my ACOS system:

Dec 07 2017 14:26:28 Warning [ACOS] Obtaining Address/Port from NAT Pool Nat-137 failed due to  
Honor Misses  
Dec 07 2017 14:24:01 Warning [ACOS] Obtaining Address/Port from NAT Pool Nat-Uss-2 failed due to  
Honor Misses  
Dec 07 2017 14:22:39 Warning [ACOS] Obtaining Address/Port from NAT Pool Nat-168 failed due to  
Honor Misses  
Dec 07 2017 14:17:42 Warning [ACOS] Obtaining Address/Port from NAT Pool Nat-169 failed due to  
Honor Misses

I think thats is because the port address translation are fully applied or leaving the nat port without translation applicable.

Regards!

Hello,

You might want to share more about the version of ACOS you are using and what kind of setup.

You might want to check “show slb l4” to see how often and what kind of NAT issue you have.  
Or: “show ip nat pool statistics” / “show slb server auto-nat-stats”

To see if it has to do with the pools.

I would expect the logging for a nat pool running out of available ports to be more descriptive… “NAT port ussage exceeded” but maybe you are combining auto-nat with pooll nat?  
For situations like this it is most advisable to open a support case.
