NAT logging to a local file

In this case, the destination of log-id 5 in the following example would be a local file instead of memory:

*A:left-a20>config>log# info  
---------------------------------------------- 
        file-id 5  
            description "nat logging" 
            location cf1:  
            rollover 15 retention 12  
        exit  
         
        log-id 5  
            filter 1  
            from main  
            to file 5 
        exit

The events are logged to a local file on the compact flash cf1 in a file under the /log directory.

Note: Logging to the compact flash (CF) represents a single point of failure. Performance (logs per second) of logging onto the CF is limited in comparison to other logging methods (RADIUS, Syslog, and IPFIX). Failure to generate logs because of a failed CF or performance limitation results in dropped NAT traffic. For this reason, local NAT logging in the SR OS is recommended only in a lab environment.
