# Configuring PIM-SM or PIM-SSM VLAN properties from the IP Routing menu

After you have enabled PIM on a VLAN, use the following procedure to view and edit PIM VLAN parameters from the PIM Interfaces tab accessible under the IP Routing menu. This procedure does not provide more configuration options than are available under the VLAN menu, but it does allow you to view some additional PIM parameters (such as DR) and also to view the configuration for multiple VLANs at once.

## Prerequisites

- You must enable PIM-SM globally.

- You must enable PIM-SM on a VLAN.

- Before you change the state (active or passive) of a PIM interface using the Interface Type field, first disable PIM to prevent instability in the PIM operations, especially when neighbors are present or when streams are received.

## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click PIM.

3. In the work area, click the Interfaces tab.

4. In the table, double-click the cell under the column heading for the parameter you want to change.

5. Select a parameter or value from the drop-down list.

6. Repeat the previous two steps until you have amended all of the parameters you want to change.

7. In the toolbar, click Apply.

## Variable definitions

The following table describes the fields of the Interfaces tab.

Field | Description
--- | ---
IfIndex | Specifies the VLANs configured for PIM-SM.
Address | Specifies the IP address of the PIM-SM VLAN.
NetMask | Specifies the network mask for the PIM-SM VLAN.
Enable | Specifies the status of PIM-SM on the VLAN: enabled (true) or disabled (false).
Mode | Specifies the PIM mode: sparse mode or source specific multicast mode.
DesignatedRouter | Specifies the router with the highest IP address on a LAN designated to perform the DR tasks.
HelloInterval | Specifies the interval (in seconds) the switch waits between sending hello message to neighboring switches. The default is 30 seconds.
JoinPruneInterval | Specifies the interval (in seconds) the switch waits between sending join/prune message to its upstream neighbors. The default is 60 seconds.
CBSRPreference | Specifies 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.
InterfaceType | Specifies the type of interface: active or passive.
OperState | Indicates the operating status of PIM-SM on this interface: up or down.
