Viewing the current PIM status and global configuration

Syntax:

show ip pim

Displays PIM status and global parameters.

PIM Status Shows either Enabled or Disabled.

State Refresh Interval

(sec)

Applies only to PIM-DM operation.

Join/Prune Interval Indicates the frequency with which the router

transmits join and prune messages for the multicast

groups the router is forwarding.

SPT Threshold When Enabled, indicates that, for a given receiver joining

a multicast group, an edge router changes from the RPT to

the SPT after receiving the first packet of a multicast flow

intended for a receiver connected to the router.

When Disabled, indicates that the no spt-threshold

command has been used to disable SPT operation. (See

“Changing the shortest-path tree (SPT) operation” (page 76).

Traps Enables the following SNMP traps:

neighbor-loss Sends a trap if a neighbor router is lost.

hardware-mrt-full Sends a trap if the hardware multicast router table

(MRT) is full (2048 active flows.)

software-mrt-full: Sends a trap if the software multicast router table

(MRT) is full (2048 active flows.) This can occur only

if the hardware MRT is also full.

all Enables all of the above traps.

none No traps are set.
