Usage Guidelines

The maximum committed rate refers to the maximum number of DNS reply packets that the FW can resolve per second. For the DNS reply packets that exceeds the maximum committed rate, the FW permits the packets without recording the domain name-IP address mapping.

In some scenarios that have high requirements on performance, you can tune this value accordingly.

Example

# Set the maximum committed rate for analyzing DNS reply packets to 60000.

<sysname> system-view
[sysname] dns analyze maximum-rate 60000
