Exclude Criteria Filter to Monitor Firewall Device Configuration


Firewall Analyzer offers another value added feature to filter out device configuration changes from monitoring. While generating change report between any two configuration versions, there might be requirements to exclude certain specific lines or text of configuration. For example, lines containing Cryptochecksum information, speed token, NTP clock-period should be ignored when the difference is considered. While Firewall Analyzer itself takes care of excluding information like the ones above, you can specify exclude criteria based on specific needs. Once the criteria is specified, Firewall Analyzer will exclude the lines matching the specified criteria for all devices belonging to which the exclude criteria template is created and applied. To cutail this, Firewall Analyzer offers Exclude Criteria filter. This will exclude the configurations with the selected criteria to be filtered out from monitoring.
