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.
Interfaces field descriptions
Use the data in the following table to use the Interfaces tab.
| Name | Description | 
|---|---|
| IfIndex | Shows the interface Index. This variable is a read-only field. | 
| Address | Shows the IP address of the PIM interface. This variable is a read-only field. | 
| NetMask | Shows the network mask for the IP address of the PIM interface. This variable is a read-only field. | 
| Mode | Shows the configured mode of this interface. The valid modes are SSM and sparse. This variable is a read-only field. | 
| InterfaceType | Specifies if the interface is active or passive. | 
| DR | Shows the router with the highest IP address on a LAN designated to perform these tasks. | 
| HelloInterval | Specifies how long to wait (in seconds) before the PIM router sends out the next hello message to neighboring switches. The default is 30 seconds. | 
| JoinPruneInterval | Specifies how long to wait (in seconds) before the PIM router sends out the next join or prune message to its upstream neighbors. The default is 60 seconds. | 
| CBSRPreference | Configures the preference for this local interface to become a C-BSR. The C-BSR with the highest BSR priority and address is the preferred BSR. The default is –1, which indicates that the current interface is not a C-BSR. | 
| OperState | Indicates the status of PIM on this interface: Up or Down. |
