You can control the thresholds NetMRI uses on certain devices and interface-related issues. Through the use of Device Groups and Interface Groups, you can modify the thresholds for any one of these issues to control when the issue is raised. This capability means that the same issue can be raised for different devices, but each device can have a different threshold for the issue.

Specific Issue types can be set to fire only on specific device groups and on specific interface groups.

Set thresholds using the Criteria property available on the **Settings** icon > **Issue** **Analysis** > **Issue** **Group** **Settings **>** Device** **Groups** side tab and **Interface** **Groups** side tab.  
Click the *Comprehensive* *Issue* *List* under Additional Documentation in Online Help for more detailed Issue listings to assist in decisions on which issues to isolate to specific device groups or interface groups.
