Editing PIM interface parameters
Edit PIM parameters for an interface to customize the PIM configuration.
Before you begin
Before you change the state (active or passive) of a PIM interface, first disable PIM to prevent instability in the PIM operations, especially when neighbors exist or when the interface receives streams.
Procedure
- In the navigation pane, expand the following folders: .
 - Click PIM.
 - Click the Interfaces tab.
 - Edit the fields by double-clicking on them, and then select or type the new value.
 - Click Apply.
