Configuring Basic Functions Of Igmp Snooping; Configuration Prerequisites; Enabling Igmp Snooping - HP A5500 SI Switch Series Configuration Manual

Task
NOTE:
In IGMP snooping view, configurations that you make are effective on all VLANs. In VLAN view,
configurations that you make are effective on only the ports that belong to the current VLAN. For a
given VLAN, a configuration that you make in IGMP snooping view is effective only if you do not
make the same configuration in VLAN view.
In IGMP snooping view, configurations that you make are effective on all ports. In Ethernet interface
view or Layer 2 aggregate interface view, configurations that you make are effective only on the
current port. In port group view, configurations that you make are effective on all ports in the current
port group. For a given port, a configuration that you make in IGMP snooping view is effective only if
you do not make the same configuration in Ethernet interface view, Layer 2 aggregate interface view,
or port group view.
For IGMP snooping, configurations that you make on a Layer 2 aggregate interface do not interfere
with configurations that you make on its member ports, nor do they participate in aggregation
calculations. Configurations that you make on a member port of an aggregate group do not take
effect until it leaves the aggregate group.
