Privilege Description
Admin EXEC When IGMP snooping and
MLD snooping are dis-
abled, router port actions
cannot be set.
Disabling IGMP snooping &
MLD snooping will flood
multicast traffic to all mem-
bers of the VLAN.
When the action is a router
port flood or drop, it will
delete the unknown multi-
cast group entry.
Admin EXEC "No IP IGMP snooping vlan
1 (last-member-query-count
| last-member-query-inter-
val | query-interval |
response-time | robustness-
variable)" will set the VLAN
parameters to default.
The CLI setting will change
the IP IGMP VLAN parame-
ters admin settings.
