# Configuring global PIM-SM status and properties using EDM

Use the following procedure to configure PIM-SM status and properties globally.

## Prerequisites

- You must enable PIM-SM globally.

## Procedure steps

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

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

3. In the Globals tab, select the Enable check box to enable PIM-SM.

4. Configure the other parameters as required.

5. In the toolbar, click Apply.

## Variable definitions

Field | Description
--- | ---
Mode | Displays the PIM mode on the switch: sparse mode or source specific multicast mode.
Enable | Enables or disables PIM globally.
JoinPruneInterval | Specifies how long (in seconds) the PIM router waits between sending join/prune messages to its upstream neighbors. The range is 1–18724, and the default is 60 seconds.
RegisterSuppTimer | Specifies how long (in seconds) the DR suppresses sending register messages to the RP after the DR receives a register-stop message from the RP. The range is 5–65535, and the default is 60 seconds.
UniRouteChgTimeOut | Specifies how often (in seconds) the switch polls the routing table manager (RTM) for unicast routing information updates to be used by PIM. The range is 2–65535, and the default is 5 seconds. Important Lowering this value increases how often the switch polls the RTM. This can affect the performance of the switch, especially when a high volume of traffic is flowing through the switch.
DiscardDataTimeOut | After the router forwards the first source packet to the RP, this value specifies how long (in seconds) the router discards subsequent source data while waiting for a join from the RP. An IPMC discard record is created and deleted after the timer expires or after a join is received. The range is 5–65535, and the default is 60 seconds.
CRPADVTimeOut | Specifies how often (in seconds) routers that are configured as candidate RPs send candidate rendezvous point (C-RP) advertisement messages. After this timer expires, the C-RP sends an advertisement message to the elected BSR. The range is 5–26214, and the default is 60 seconds.
BootStrapPeriod | Specifies the interval (in seconds) that the elected BSR waits between originating bootstrap messages. The range is 5–32757, and the default is 60 seconds.
StaticRP | Enables or disables the static RP feature. Static RP permits communication with routers from other vendors that do not use the BSR mechanism. By default, static RP is disabled.
FwdCacheTimeOut | Specifies the PIM forward cache expiry value in seconds. This value is used in aging PIM mroutes in seconds. The range is 10–86400, and the default is 210.
