Deleting and Resetting IP Multicast Settings

To return IP multicast routing settings to their defaults and disable IP multicast routing functions, use 
the commands listed in Table 64.

show ipmc cache {detail} {<group>} {<source> 
<netmask>}}

Displays the IP multicast forwarding cache.

Table 64: IP Multicast Routing Reset and Disable Commands

clear igmp snooping {vlan <name>}

Removes one or all IGMP snooping entries.

clear ipmc cache {<group> {<source> 
<netmask>}}

Resets the IP multicast cache table. If no options 
are specified, all IP multicast cache entries are 
flushed.

disable igmp {vlan <name>}

Disables the router-side IGMP processing on a 
router interface. No IGMP query is generated, but 
the switch continues to respond to IGMP queries 
received from other devices. If no VLAN is 
specified, IGMP is disabled on all router 
interfaces.

disable igmp snooping

Disables IGMP snooping. IGMP snooping can be 
disabled only if IP multicast routing is not being 
used. Disabling IGMP snooping allows all IGMP 
and IP multicast traffic to flood within a given 
VLAN.

disable ipmcforwarding {vlan <name>}

Disables IP multicast forwarding.

unconfig igmp

Resets all IGMP settings to their default values 
and clears the IGMP group table.
