Usage Guidelines
• If the IGMP zapping is already enabled on the system, then the VLAN configuration will override the
system's configuration.
• IGMP zapping refers to processing membership, immediate source filter removals and will not wait for
the protocol's specified time period. This mode facilitates IP TV applications looking for quick changes
between IP multicast groups.
• You can also restore the IGMP querying to its default (i.e., disabled) setting on the system if no VLAN
is specified, by using only ip multicast zapping (e.g., ip multicast zapping).
• You can also restore the IGMP querying to its default (i.e., disabled) setting on the specified VLAN,
by using only ip multicast vlan vid zapping (e.g., ip multicast vlan 2 zapping).
Examples
