Displaying PIM-Specific Data
The commands in this section display PIM-specific multicast routing informa
tion for IP multicast groups detected by the router.
Displaying 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.
Refer to "Displaying PIM Status" on page 3-28.
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. (Refer to "Changing the
Shortest-Path Tree (SPT) Operation" on page 4-42.)
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 (MRT) table is full (2048 active flows).
software-mrt-full: Sends a trap if the software multicast
router (MRT) table is full (2048 active flows). This can
occur only if the hardware MRT is also full.
all: Enables all of the above traps.
