At the same time, you should pay attention to the configuration of Unicast
Routing Protocol, assure that each device can communicate with each other in the
network layer, and be able to implement dynamic routing update in virtue of Unicast
Routing Protocol.
16.2.5 PIM-DM Troubleshooting
In configuring and using PIM-DM Protocol, PIM-DM Protocol might not operate
normally caused by physical connection or incorrect configuration. Therefore, the user
should pay attention to the following issues:
z To assure that physical connection is correct.
z To assure the Protocol of Interface and Link is UP (use show interface command);
z To assure PIM Protocol is enabled in Global Mode (use ipv6 pim multicast-routing )
z Enable PIM-DM Protocol on the interface (use ipv6 pim dense-mode command)
z Multicast Protocol requires RPF Check using Unicast routing; therefore the
correctness of Unicast routing must be assured beforehand.
If all attempts including Check are made but the problems on PIM-DM can’t be
solved yet, then use debug commands such as debug pim please, and then copy
DEBUG information in 3 minutes and send to Technology Service Center.
16.2.5.1 commands for Monitor and debug
16.2.5.1.1 debug pim timer sat
Command: debug pim timer sat
no debug pim timer sat
Function: Enable debug switch of PIM-DM source activity timer information in detail; the
“no debug pim timer sat” command disenables the debug switch.
Parameter: None.
Default: Disabled.
Command Mode: Admin Mode.
Usage Guide:
Enable the switch, and display source activity timer information in detail.
Example:
Switch # debug ip pim timer sat
Remark: Other debug switches in PIM-DM are common in PIM-SM, including debug pim
