C H A P T E R 1 2 IP Multicast Routing
Deleting and Resetting IP Multicast Settings
To return IP multicast routing settings to their defaults and disable IP
multicast routing, use the command listed in Table 60.
Table 60: IP Multicast Routing Reset and Disable Commands
Command Description
disable dvmrp Disables DVMRP on the system.
disable ipmcforwarding {vlan
<name>} Disables IP multicast forwarding.
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 pim Disables PIM-DM on the system.
unconfig dvmrp {vlan <name>} Resets the DVMRP timers to their default settings. If
no VLAN is specified, all interfaces are reset.
unconfig igmp Resets all IGMP settings to their default values and
clears the IGMP group table.
unconfig pim {vlan <name>} Resets all PIM-DM settings to their default values.
clear igmp snooping {vlan <name>} Removes one or all IGMP snooping entries.
clear ipmc cache {<group>
{<src_ipaddress> <mask>}} Resets the IP multicast cache table. If no options are
specified, all IP multicast cache entries are flushed.
