The mapping facility also has the ability to exclude certain devices from being mapped. These rules are also the same syntax as the mapping rules, but are less complex. They do not require a destination, since they specify an exclusion. Here are some examples.

Exclude all devices from the 172 network

.*   IP 

Exclude all hosts going from Smarts Manager to Network Configuration Manager

.*   DeviceType   Host

Exclude any device whose name matches the regular expression “edge.*” coming NetworkA.

NetworkA   Name   edge.*

Exclusion rules only require an origin and a filter, and still follow the syntax for mapping rules previously detailed.
