For a specific device type, you can map multiple parser variables of the same type to retrieve data for different models or OS versions, and then prioritize them.
Example: Prioritize two CLI parsers for Cisco Router: apply the parser "BGP Summary" for model 6500, and apply the parser "BGP Neighbor" for others.
Note: The priority setting is synchronized across domains under one tenant.
1.Click the start menu
and select Variable Mapping.
2.In the Variable Mapping page, select BGP Summary as the reference parser.
3.In the table header Cisco Router, click the
icon. The mapped two parsers for are auto-populated. By default, newly mapped parsers have higher priority.

4.Adjust the order by sorting filter criteria of parsers, and click Save.
Note: Parsers with Filter Criteria configured are recommended to have higher priority.
a)When a device matches the filter criteria of the first-priority parser, this parser will be applied on the device. If this parser covers all variables, then lower-priority parsers will not be applied to this device.
b)When a device doesn’t match the filter criteria of the first-priority parser, it will poll lower ones until it has a match. Then Rule a) is applied.
