MLD 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. Devices in this chapter are categorized
depending on their IRF capability and support for interface cards that use independent processors for
forwarding traffic, as shown in Table 1.

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