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 Mode Description
ip igmp filter port PORTS profile
<1-2147483647>
Global
Applies an IGMP profile to ports
PORTS: port number (1/1, 1/2, 2/1, …)
1-2147483647: IGMP profile number
no ip igmp filter port PORTS Releases an applied IGMP profile.
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, V8102 can permit or deny the IGMP packets by referring to its
DHCP snooping binding table. This reference enables the system to permit IGMP mes-
sages 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 Mode Description
ip igmp filter port PORTS permit
dhcp-snoop-binding

on the DHCP snooping binding table.
no ip igmp filter port PORTS

Adds the entry to IGMP snooping table irrespective of
DHCP snooping binding table.

mand.
