Description
Enable or disable the function of dropping unknown multicast packets.
Unknown multicast data refer to multicast data for which no entries exist in the IGMP
snooping forwarding table.

With the function of dropping unknown multicast data enabled, the switch drops
all the unknown multicast data received.

With the function of dropping unknown multicast data disabled, the switch floods
unknown multicast data in the VLAN to which the unknown multicast data
belong.
Enable or disable the IGMP snooping querier function.
On a network without Layer 3 multicast devices, no IGMP querier-related function
can be implemented because a Layer 2 device does not support IGMP. To address
this issue, you can enable IGMP snooping querier on a Layer 2 device so that the
device can generate and maintain multicast forwarding entries at data link layer,
thereby implementing IGMP querier-related functions.
Configure the IGMP query interval.
Specify the source IP address of general queries. HP recommends you to configure a
non-all-zero IP address as the source IP address of IGMP queries.
Specify the source IP address of group-specific queries. HP recommends you to
configure a non-all-zero IP address as the source IP address of IGMP queries
list.
