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.
The procedures to manage and create the Exclude Criteria are given below.
The Template table contains the following columns.
Columns | Description |
---|---|
Template Name | Name of the Exclude Criteria template |
Device Type | Name of the devices the exclude criteria template is applied |
Status | Enable/Disable - Toggle the slider to enable or disable the Exclude Criteria template |
While generating configuration difference between any two configuration file versions, there might be requirements to exclude certain specific lines or text. For example, lines containing Cryptochecksum information, speed token, NTP clock-period should be ignored while taking the difference. While Firewall Analyzer takes care of excluding information like the ones above, users 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 the device template for which the exclude criteria is created.
You may make use of Regular Expressions while specifying the Exclude Criteria. For instance, if you wish to exclude the lines containing the text "logging" followed by an IP address, you may specify the criteria as 'logging.*'
