IGMP snooping debugging commands
The MCS module name is identified as "multicast" in debugging messages.
The output description tables in this document only contain fields and messages that require an
explanation.
Some information in this chapter is device type specific. This document categorizes devices depending
on their IRF capability and support for interface cards that use independent processors for forwarding
traffic, as shown in Table 1.

debugging igmp-snooping
Use debugging igmp-snooping to enable IGMP snooping debugging.
Use undo debugging igmp-snooping to disable IGMP snooping debugging.
Syntax
Centralized devices:
debugging igmp-snooping { abnormal | all | driver | event | group | packet [ vlan vlan-id ] [ port
interface-type interface-number ] | timer }
undo debugging igmp-snooping { abnormal | all | driver | event | group | packet | timer }
Distributed devices/centralized IRF devices/distributed IRF devices:
debugging igmp-snooping { abnormal | all | driver | event | group | ipc { receive | send } | packet
[ vlan vlan-id ] [ port interface-type interface-number ] | timer }
undo debugging igmp-snooping { abnormal | all | driver | event | group | ipc { receive | send } |
packet | timer }
