no debug igmp {all | decode | encode | events | fsm | tib}
all
Debug all information of IGMP.
decode IGMP decode.
encode IGMP encode.
events Debug events of IGMP.
fsm IGMP FSM.
tib IGMP Tree-Info-Base (TIB).
Command Mode
Privileged EXEC
Usage
This command helps discover whether the IGMP processes are functioning. In general, if IGMP is not
working, the process never discovers that another host is on the network that is configured to receive
multicast packets. In sparse mode, packets will never be delivered.
Use this command in conjunction with the debug pim commands to observe additional multicast
activity and to learn the status of the multicast routing process, or why packets are forwarded out of
particular interfaces.
Examples
The following is sample output from the debug ip igmp command:
Switch# debug ip igmp
