2.
Configure the settings as described in the following table.
Setting
Description
IGMP Snooping Status
Specify the IGMP snooping status:
Enable
. The smart switch snoops all IGMP packets that it receives to
determine which segments should receive packets directed to the group
address.
Disable
. The smart switch does not snoop IGMP packets. This is the
default setting.
Validate IGMP IP header
Specify whether the IGMP IP header is validated:
Enable
. The smart switch checks the IP header of all IGMP messages for
the Router Alert option, ToS, and TTL. If any of the options are not present
or set incorrectly, the packet is dropped.
Disable
. The smart switch does not check the IGMP IP header for the
Router Alert option, ToS, and TTL.
Block Unknown Multicast
Address
Specify whether unknown multicast addresses are blocked:
Enable
. The smart switch drops packets with an unknown multicast MAC
address in the destination field.
Disable
. The smart switch processes packets with an unknown multicast
MAC address in the destination field.

The following table describes the global IGMP snooping status and statistics fields that
are shown on the screen.
Field
Description
Multicast Control Frame
Count
