clear ip igmp group [group-name | group-address | typenumber]
group-name (Optional) Name of the multicast group, as defined in the DNS hosts table or with the ip host command.
group-address (Optional) Address of the multicast group. This is a multicast IP address in four-part, dotted notation.

The IGMP cache contains a list of the multicast groups of which hosts on the directly connected LAN are members. If the router has joined a group, it is also listed in the cache.
To delete all entries from the IGMP cache, specify the clear ip igmp group command with no arguments.
The following example clears entries for the multicast group 224.0.255.1 from the IGMP cache:
clear ip igmp group 224.0.255.1
| Command | Description |
|---|---|
| ip host | Defines a static host name-to-address mapping in the host cache. |
| show ip igmp groups | Displays the multicast groups that are directly connected to the router and that were learned through IGMP. |
| show ip igmp interface | Displays multicast-related information about an interface. |
