Using PIM Debugging Commands

Use Protocol Independent Multicast (PIM) traces to aid in PIM troubleshooting.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Start debug trace message output:

debug ip pim pimdbgtrace
Stop debug trace message output:

no debug ip pim pimdbgtrace

default debug ip pim pimdbgtrace
Configure the system to display trace messages forwarded by the device:

debug ip pim send-dbg-trace
Stop the system from displaying trace messages forwarded by the device:

no debug ip pim send-dbg-trace

default debug ip pim send-dbg-trace
Configure the system to display trace messages received by the device:

debug ip pim rcv-dbg-trace
Stop the system from displaying trace messages received by the device:

no debug ip pim rcv-dbg-trace

default debug ip pim rcv-dbg-trace
Configure the system to display hello messages forwarded or received by the device:

debug ip pim hello
Stop the system from displaying hello messages forwarded or received by the device:

no debug ip pim hello

default debug ip pim hello
Configure the system to display and log debug trace messages:

debug ip pim pimdbglog
Stop the system from displaying and logging debug trace messages:

no debug ip pim pimdbglog

default debug ip pim pimdbglog
Configure the system to display register messages forwarded or received by the device:

debug ip pim register
Stop the system from displaying register messages forwarded or received by the device:

no debug ip pim register

default debug ip pim register
Configure the system to display debug trace messages after an enabled message type, for example, hello or register, is received from a specific sender IP address:

debug ip pim source {A.B.C.D}
