Enabling IGMP Filtering
To enable IGMP filtering for a port, a configured IGMP profile needs to be applied to the
port.
To apply an IGMP profile to ports to enable IGMP filtering, use the following command.
Command
ip igmp filter port PORTS profile
<1-2147483647>
no ip igmp filter port PORTS
Before enabling IGMP filtering, please keep in mind the following restrictions.
Plural IGMP profiles cannot be applied to a single port.
•
IGMP snooping must be enabled before enabling IGMP filtering.
•
To delete a created IGMP profile, all ports where the profile applied must be released.
•
IGMP filtering only supports IGMPv2.
•
By the following command, this switch can permit or deny the IGMP packets by referring
to its DHCP snooping binding table. This reference enables the system to permit IGMP
messages only when the source IP address and MAC address of host have identified
from the DHCP snooping binding table.
To permit/discard IGMP packets for the hosts authorized by the DHCP snooping, use the
following command.
Command
ip igmp filter port PORTS permit
dhcp-snoop-binding
no ip igmp filter port PORTS
permit dhcp-snoop-binding
To allow or discard IGMP messages by message type on a port, use the following com-
mand.
Command

–type { reportv1 | reportv2 | re-
portv3 | query | leave | all }
no ip igmp filter port PORTS
